The human heart contracts from the first moment of life until the last one. The contractions of the heart pump the blood through the arteries to all the parts of the body. Physiologists have determined that in the adult the heart makes from 60 to 72 beats per minute. In children the rate of heart beat is much higher. Research work has determined that rate of heart beat increases depending on different emotions. Each beat of the heart is followed by a period of rest. Each contraction and a period of rest compose a cardiac cycle. Each cardiac cycle consists of three phases: the first phase of short contraction - the atrial systole, the second phase of a more prolonged contraction - the ventricular systole. The period of rest is called the diastole. Research work of many physiologists has estimated the role of the ventricles as the main pump of the human heart. Task 3: The biggest and the smallest blood vessel in our body … ? The aorta is the largest blood vessel in the human body. It originates from the left ventricle of the heart and distributes blood to the rest of the body by ramifying itself in a masterful array of smaller arteries. The smallest blood vessels in the human body are capillaries, which connect arteries and veins. Capillaries can be as small as 5 micrometers wide. The average adult body has about 10 billion capillaries. Capillaries are part of the circulation system in the human body. They help move oxygen, water, carbon dioxide and other nutrients throughout the body. Arteries transfer blood out of the heart. Arteries narrow into capillaries, then widen into venules and veins. The veins transport blood back into the heart. Capillaries work as a group and not individually. During exercise, capillaries assist the lungs with meeting the need for increased blood flow. Task 4: What are the elements of blood and their functions? Red Blood Cells White Blood Cells Platelets •The red blood cells are also known as erythrocytes and these are the most predominant cells in the blood. They contain hemoglobin which is a protein that contains iron and are responsible for transporting oxygen and carbon dioxide which is dissolved extracellularly as a bicarbonate ion within the plasma. •The white blood cells, one of the 3 formed elements of blood, also known as leucocytes are tasked with defending the body against bacteria, viruses and parasites. These blood cells can fight disease in various ways. They could either produce antibodies that overpower germs or surround and devour any bacterial presence. •Platelets are colorless and shaped irregularly. Their surface is sticky in nature and this is what makes them the blood clotting element in the blood. The body naturally controls blood loss and it protects itself by sending the platelets to clot blood and consequently prevent hemorrhage. These platelets surround the wound with the help of vitamin K, calcium and fibrinogen which is a protein. Task 5: What kind of heart sounds do you know? When we listen to the heart we can hear two sounds. The third sound is also heard in some young persons before the age of 30. The first heart sound is the longest one. It is heard at the moment of contraction of the ventricles when the atrio-ventricular valves close. The second sound lasts for a shorter period of time. It is heard at the moment when the pulmonary and aortic semi lunar valves close. The third heart sound is heard when the blood is passing from the atria into the ventricles. Task 6: What is the average weight and size of the human lungs? Task 7: Describe the human respiratory system. Task 8: Describe the human brain anatomy. Task 9: Describe the classification of the reflexes. Task 10: Write the definitions to the following words: Blood, blood vessel, bloodstream, blood pressure, to pump, aorta, artery, pulmonary artery, veins, vena cava, capillary. Task 11: Write the types of Microorganisms. Task 12: The brief information about virology and its founder. Task 13: Write 3 essential events of your Country, using official data, facts and statistics. Task 14: Write your own opinion about “The role of family polyclinics in our life”. Task 15: What does an in-patient depart mean? And its function? Task 16: Write the information about the founder of the X-rays. Task 17: What kind of symptoms and causes of cholera bacterium do you know? Task 18: You are given 17 tasks above according to your lessons that you have learned. Write them correct answers by yourself, without “COPY and PASTE!!!” Thanks in advance. We wish you a good luck and health!
