PRESENTATION OF THE LESSON Based on the video that we’ve watched and sing, what have you noticed? “Wow, Very Good!” For this morning our discussion will be circulatory system and the mechanism how the respiratory and circulatory systems work together. C. LESSON PROPER 1. Activity Instruct the learners to form 4 groups and each group will be given with specific task. Group 1 – Picture Analysis You are given with the following pictures and diagrams. Analyze each by answering the questions below. 1. The song is all about circulatory system, it's organs and functions. 2. In a circulatory system, there are mentioned parts. These are heart, blood, and blood vessels. Under heart there is atria ventricles. In vessels, there are arteries 3. Heart works by producing blood that circulates throughout the body. There is blood that is moving in or out of the heart. The blood vessels are the passage of the blood. Also, blood passes through the heart twice pumped from right side heart to the lungs sac and picks up oxygen. It returns to the left side, pumped and gives oxygen. Figure 1 http://www.mstworkbooks.co.za/natural-sciences/gr9/gr9-ll04.html Figure 2 https://www.khanacademy.org/science/health-andmedicine/circulatory-system/circulatory-system-introduction/v/flowthrough-the-heart Guide Questions 1. What are the three major organs of the circulatory system? Indicate their functions. 2. Explain the general flow of the blood in the body based on Figure 2. 1. The three major organs in circulatory system are Heart, blood vessels and blood. The Heart is muscular organ that pumps blood throughout your body. Meanwhile blood vessels, which include your arteries, veins and capillaries is responsible for to deliver blood to the organs and tissues in your body. Lastly, blood is made up of red and white blood cells, plasma and platelets that has a function of transporting oxygen and nutrients to the lungs and tissues. 2. As the heart beats, it pumps blood through a system of blood vessels, called the circulatory system. The vessels are elastic, muscular tubes that carry blood to every part of the body. In addition, blood is essential. In addition to carrying fresh oxygen from the lungs and nutrients to your body's tissues, it also takes the body's waste products, including carbon dioxide, away from the tissues. This is necessary to sustain life and promote the health of all the body's tissues. Group 2 – Video Analysis Watch the 6-minute video about circulatory system. Guide Questions 1. What is the function of the following: a. Heart b. Blood c. Blood Vessel 2. How does blood circulate on your body? Flowchart may be used. 3. Would there be a chance that the blood may flow faster than its normal flow? How does it affect pulse rate? (Your output in picture and video analysis will be assessed in accordance with the following rubric) Group 3 – Pulse Rate Activity Perform the procedure to determine the relationship between physical activity and pulse rate. 1. Count your pulses for 15 seconds. Multiply this by four to obtain your pulse rate per minute. (A person’s pulse rate is a direct measure of heart rate. Normal resting heart rate of an adult is 60 to 100 beats per minute.) 1. The heart pulls the blood into it and pushes it back again. This helps the blood to move enough to go through your whole body and back. The blood picks up and drop off things all the time in our body. While, the blood vessels are like tiny tunnels that run all through your body. They are made up of arteries that take oxygen to places in your body and veins that take carbon dioxide from your body to your lungs. 2. The blood coming from the body will enter the heart through the right atrium, while the blood coming from the lungs will enter the heart through left atrium. Then, it will exit from the heart and move into the body through left ventricle, while it will exit from the heart and move to the lungs through right ventricle. And, repeating the process which are called as cycle. 3. Yes, Sir/Ma'am. This is through physical activities such as running and walking, because it will result to a faster heartbeat. With this, the flow of our blood throughout our body will get faster than its normal rate. Thus, faster heartbeat is synonymous to faster pulse rate. 2. Do the ‘jumping jack’ activity for 16 counts. Try taking your pulse rate again. Count your pulse for 15 seconds and multiply it by 4. 3. Discuss in the group: a. Did you get the same number of pulse per minute? Why do you think so? 4. What is the relationship between the physical activity and pulse rate? Record the Data using the table below. Student Pulse Rate Resting After Exercising A B C Group 4 – Simulation Dramatization of the Blood's Trip Through the Heart (Science/Dramatics Connection) Objective: to describe the blood's trip through the body and the function of the heart Materials: diagram of circulatory system "oxygen" tags a. No, because the pulse rate depends on the physical activity. After undergoing a physical activity, the pulse rate is fast and after resting and counting it again, it is now different from the previous one. 4.The pulse rate following exercise is directly related to the intensity of the exercise and the resting rate. The rate of deceleration following exercise is directly related to the intensity of the exercise and the elevation of the pulse rate immediately after exercise. (Students will present their recorded data using the table) "carbon dioxide" tags Procedure: 1. Set up a large room sized diagram of the circulatory system. 2. Students assume the roles of "body organs and parts." This should include heart, lungs, arms, legs, etc. 3. Other students act as the "blood." As the "blood" travels from the heart to the lungs, students simulating the blood should be given several tags labeled "oxygen." 4. The "blood" then travels back to the heart and to the other parts of the body. As the "blood" travels to each body part, it exchanges "oxygen tags" for tags labeled "carbon dioxide" and "other wastes." 5. When the oxygen is used up, the "blood" then must travel back to the heart and lungs to exchange the "carbon dioxide and waste" for new "oxygen." 6. Choose one documenter of the activity. After performing the simulation, share your experiences and ideas you have come up to the whole class. 2. Analysis What did you notice upon doing these activities? What strategy did you used in performing the simulation? Do you think it has a connection to our topic? How do you say so? (Students will share their experiences and ideas they have come up upon performing the simulation) Sir/Ma'am, in these activities I noticed the importance of our circulatory system. In which, the heart, the blood vessels and blood are the three components of circulatory systems. And, our pulse rate has something to do with our physical activities. Sir/Ma'am, we did the simulation in a systematic manner. Each of us played our roles as if we are the circulatory system. 3. Abstraction The circulatory system is the life support structure that nourishes your cells with Yes, Sir/Ma'am. Because, the activities showcase nutrients from the food you eat and oxygen what really happened in an actual circulatory system. from the air you breathe. Another name for the circulatory system is the cardiovascular system. The circulatory system functions with other body systems to deliver different materials in the body. It circulates vital elements such as oxygen and nutrients. At the same time, it also transports wastes away from the body. The following are the three major parts of the circulatory system, with their roles: 1. Heart – pumps the blood throughout the body 2. Blood vessel – carries the blood throughout the body a. Arteries - carry oxygenated blood away from the heart to the cells, tissues and organs of the body b. Veins - carry deoxygenated blood to the heart c. Capillaries - the smallest blood vessels in the body, connecting the smallest arteries to the smallest veins - the actual site where gases and nutrients are exchanged 3. Blood – carries the materials throughout the body The Human Heart Do you know how big your heart is? Take a look at your fist. The heart is a hollow muscle which is just as big as your fist. It has four chambers with specific tasks to do: two ventricles and two atria. The atria are the receiving chambers of the heart, accepting blood from the body (right atrium) and from the lungs (left atrium). The ventricles are the pumping chambers, moving blood to the lungs (right ventricle) and into the body (left ventricle). The Human Heart Major Division of Heart Mechanism of how the respiratory and circulatory systems work together The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air first enters your lungs and then into the left part of your heart. It is then driven by your heart into the bloodstream, all the way through your body. The heart pumps blood, which transports essential nutrients, oxygen, and other chemicals to every cell in your body. Once it reaches the cells; oxygen processes the nutrients to release energy. Carbon dioxide is given off during this process. The blood delivers carbon dioxide into the right portion of your heart, from which it is pumped to the lungs. Carbon dioxide leaves your body through the lungs when you exhale. 4. Application Perform the activity below to show and explain the mechanism of how the respiratory and circulatory systems work together Just Go with the Flow! Objectives: Describe blood flow and gas exchange within the heart, circulatory system, and lungs Explain the mechanism of how the respiratory and circulatory systems work together Materials: Paper strips Rope or ribbon Marking pen Chalk Procedure: 1. Perform the activity with your group mates (7-8 persons). 2. Assign and label different areas in the outdoor setting as: lungs, left atrium, left ventricle, arteries, capillary, veins, right ventricle, and right atrium. 3. Using the marking pen, write down the word oxygen on as many paper strips as you can and place them in the lung area. The capillary area should have papers with carbon dioxide written on them. 4. Use the chalk to mark and define the different areas such as what is given in the diagram below. Assign some members of your group to stand still on the different marked areas. Illustration of the gas exchange activity 5. Choose two members from the group to take the trip around the different posts. Let the partners start the tour in the lung area and together pick up a paper labeled as oxygen from another member standing at his post. They should carry the strip of paper to the heart, passing through the left atrium, and then to the left ventricle. As the partners go to every station, they must leave a trail of rope or ribbon held by another member in a designated area, until the path of the journey is completely traced. 6. Partners must run along the chalk marks representing the arteries into the capillary area. 7. Tell the partners to exchange the strip of paper representing oxygen for a piece of paper representing carbon dioxide with a member in his designated area. 8. Make the partners run along the chalk marks representing the veins into the heart area, first to the right ventricle, then to the right atrium. 9. The partners must then run back into the lung area where the process begins again. When there are no more strips of paper, the activity is over. The leader may want to keep placing new papers into designated areas to keep the game going on longer. 10. After the activity, record your observations and answer the guide questions Guide Questions: 1. How do the heart and the lungs work together? 2. What takes place when you inhale and exhale? 3. What does blood deliver to every part of the body? 4. Why is oxygen important to your body? 5. How will you describe the sequence of oxygen, carbon dioxide, and blood flow in your own words? IV. EVALUATION Multiple Choice: Read and analyze each item carefully. Choose and encircle the letter of the best answer. Use the figure below to answer questions 1 and 2. 1. What important process happens in the netlike structure labeled A? A. Nitrogen and oxygen are exchanged. B. Carbon dioxide and oxygen are exchanged. C. Nitrogen and carbon dioxide remain constant. D. Carbon dioxide and oxygen diffuse into the blood. 2. What structure of the Respiratory System is labeled B in the diagram? A. Alveolus C. Bronchiole B. Bronchi D. Pharynx 1. they are partners working to make sure your entire body gets the oxygen needed. 2. Breathing (or ventilation) is the process of moving air into and from the lungs to facilitate gas exchange with the internal environment 3. Blood brings oxygen and nutrients to all the parts of the body so they can keep working. 4. Oxygen is important because it gives energy to our cells to work not only the cells but also the cell organelles. 5. Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and then exhaled. Then the blood is pumped through the pulmonary artery to the lungs, where it picks up oxygen and releases carbon dioxide. 3. Why is the lung considered as the primary organ of the respiratory system? A. Because it is the largest organ of the system. B. Because it has two parts: the right and left lungs. C. Because it is located near the middle of the chest cavity. D.

Work together only when we are active, and never when we are resting or sleeping. D. Work together to deliver oxygen to cells and remove carbon dioxide from the body. V. ASSIGNMENT Goal: Your objective is to present helpful information to the public about effective ways of taking care of the respiratory and circulatory systems based on gathered data. The challenge is how you will be able to lead the people to take action rather than merely accepting the presented information. There are obstacles to overcome such as the reluctance and preconceived notion of people against changing their lifestyle to promote health. Role: Suppose you work for an advertising company as a graphic artist and your job is to create public informational materials. You are asked to disseminate information to the public regarding a lifestyle that ensures healthy condition of the respiratory and circulatory systems. Audience: Your target individuals to receive the information that you will provide are the people in your school community including all students, teachers, and school officials. Parents and other persons who visit your school might also see your work. Therefore, it is important that you convince them to consider the ways of taking care of their bodies, specifically the circulatory and respiratory systems. Situation: Upon gathering information from the school or local health workers, you have found out that poor lifestyle affects the performance of the respiratory and circulatory systems. Many people are unaware of this, so they simply continue with their busy lifestyles, neglecting their health, and exploiting their bodies. The challenge involves dealing with this by creating a poster that will stir up the people’s consciousness in having a healthy lifestyle. Product: Design a wall poster or placard that will make members of your audience aware of how they can effectively take care of their respiratory and circulatory systems. You may use any medium for your artwork. Standards: You will be given three (3) days to conceptualize and execute your ideas through poster-making. Once the product is finished, post it in a conspicuous place such as the canteen where everyone can see it.
