Have fun! JQ: Is an Avatar living or non-living? How do you construct an Avatar? “Good science is good observation!” What does that mean? Quick Dissection Activity and Data Collection In order to understand how we will survive space exploration, we must understand how our bodies are “put together” To review organ systems thru dissection video: http://www.youtube.com/user/LakelandBiology Levels of Organization Organism Organ System Organ Tissue Cell Organelle Macromolecule Molecule Atom Subatomic Particles How can I remember all eleven organ systems? C DR SMILE RUN Cardiovascular Digestive Respiratory Skeletal Muscular Integumentary Lymphatic Endocrine Reproductive Urinary Nervous Circulatory System Function – transports substances throughout the body using heart Organs – heart, arteries/veins & blood Digestive System Function – breaks down food into usable substances & absorption through intestines Organ – esophagus, stomach, and intestines Respiratory System Function – moves air in and out of lungs Organ – trachea, pharynx, bronchi and lungs (diaphragm helps) Skeletal System Function – provides support and structure to the body, site for blood production (red and white cells), Organ – Bones Muscular System Function – allows your body to move through contraction and relaxation Organs– muscles Integumentary System Function – serves as a barrier & protects against infection (1st line of defense) Organ – skin, nails, hair follicles, sweat glands Lymphatic System Function – defend against pathogen and disease with white blood cells (2nd line of defense) Organs –lymph nodes/lymph vessels Endocrine System Function – slowly relays messages that regulate the body (growth and development) Organs – glands Reproductive System Function – production of sperm & egg cells to create offspring. Organs – testes & penis; ovaries, fallopian tubes, uterus. Urinary System Function – filters & eliminates waste from the blood Organ – kidneys, bladder Nervous System Function – quickly relays messages to and from brain through cells called neurons that regulate behavior. Organs – brain, spinal cord, sense organs Journal Question: How can you learn about yourself by dissecting the fetal pig? Explain. What are all organ systems working toward? Homeostasis – process by which organisms keep internal conditions relatively constant despite changes in the external environment. Examples: temperature, heart rate, blood pressure, etc. Objectives: -Use technology appropriately in school -Visualize the 11 organ systems - Recognize that by studying the fetal pig you can understand how a human and is constructed. -Visualize and interconnectedness between organs and organ systems. -Develop basic dissecting skills. External Dissection 1. Determining the age of your pig. 2. Identifying the sex of the pig. External Dissection 1. Observing the Integumentary System. 2. Observing Muscular System. Male vs. Female Mouth Dissection A 1. B C Identifying the tongue, soft & hard pallet. 2. Opening of mouth to view epiglottis. D JQ: No Journal Question Today. Instead, put gloves on, your apron on, and have a seat in your desk. Your homework tonight is to complete the Dissection Lab Internal Dissection 1. Re-tie your pig to the dissecting tray. (tape?) 2. Make incisions to expose internal organs. 3. Identify all internal organs and show teacher. 4. When finished, work on Post-lab questions. Clean-up 1. Put the fetal pig into the bag provided. Label bag with you & your partners names. 2. With soap and water clean tools and tray, return to cart. 3. Wipe down table and sink with wet sponge. 4. Return to seat. Testing your skills – Name that Organ System 1. Serves as a barrier & protects against infection. 2. Quickly relays messages from one part of the body to another. 3. Breaks down food into simple molecules that can be used by cells. 4. Brings oxygen in and carbon dioxide out. 5. Filters and removes waste from the blood. 6. Produces gametes (sperm and egg) cells. 7. Provides support and is a site for blood cell formation. 8. Allows the body to move. 9. Transports substances throughout your body 10.Slowly regulates the body’s functions. 11. Protects the body from disease. Testing your skills – Name that Organ System Answers 1. Integumentary System 2. Nervous System 3. Digestive System 4. Respiratory System 5. Excretory or Urinary System 6. Reproductive System 7. Skeletal System 8. Muscular System 9.

JQ: Did the fetal pig dissection meet your expectations? Elaborate. Take out your lab. You need your textbook tomorrow. 1. Fontanelles are the “soft spots” on a young human, or pig’s skull. What would be the benefit of having spaces between the sections of the skull? Explain. 2. Humans, like the pig, have cartilidge rings holding their trachea (windpipe) open. Why do they need these rings? 1. When most organs/tissues swell, they grow bigger until the damage is fixed. What restricts the brain from swelling, and what could happen if the brain swells too much? 2. In many mammals, the lungs are late to develop. Why would they develop later than many other organs? Fetal Pig Dissection Write-up 1. What was the purpose of the fetal pig dissection? 2. Compare and contrast the organs/organ systems of the fetal pig and the avatar. 3. Why are the anatomy and physiology different between the fetal pig and the avatar? Explain JQ: What do you see? Welcome to Name that Image! How are these pictures possible?
