3. List of Circulatory System

4. Pumping action of the heart The heart pumps blood to every organ in the body. The heart pumps oxygen-blood to the arteries to send it to the organs. The veins carry the used blood cells back to the heart.

5. How the blood flow works The heart pumps oxygen- blood to the arteries to send it to the organs. The veins carry the used blood cells back to the heart. Then the venous blood is sent to the lungs to fill up with oxygen. Then it repeats.

6. Two diseases of the Circulatory system Diseases of mitral valve: The mitral valve controls the flow of blood into the left ventricle. Normally, when the left ventricle contracts the mitral valve closes and the blood flows out through the aortic valve. In mitral valve prolapse, the shape or dimensions of the leaflets of the valve are not ideal they may be too large and fail to close properly or balloon out hence the term "prolapse." Diseases of aortic valve: The aortic valve is one of four valves that control the flow of blood into and out of the heart. In particular, the aortic valve controls the flow of oxygen made blood pumped out of the heart from the left ventricle into the aorta, the main artery leading to the rest of the body. If the valve is abnormally narrow, the heart must work harder for a sufficient amount of blood to be pumped with each beat.

8. Vocabulary Aorta: the main artery that carries blood away from the heart. vena cava: The large veins leading blue or unoxygenated blood into the right heart from the body. Atrium: One of the two upper chambers of the heart. The right atrium receives unoxygenated blood from the body. The left atrium receives oxygenated blood from the lungs. Valve: a structure in a hollow organ with a flap to insure one-way flow of fluid through it Ventricle. circulatory system: pertaining to the heart and blood vessels, and the circulation of blood. pulmonary circulation: that carrying the venous blood from the right ventricle to the lungs, and returning oxygenated blood to the left atrium of the heart; called also lesser c. systemic circulation: the general circulation, carrying oxygenated blood from the left ventricle to various tissues of the body, and returning the venous blood to the right atrium of the heart; called also greater c. coronary circulation: that within the coronary vessels of the heart. red blood cells: blood cells that carry oxygen from the lungs to the rest of the body. Hemoglobin: The substance inside red blood cells that carries oxygen molecules. white blood cells: Cells that circulate in the blood and lymphatic system and congregate in the lymph glands and spleen. (The lymphatic system consists of the tissues and organs, including the bone marrow, spleen, thymus, and lymph nodes that produce and store cells that fight infection and the network of vessels that carry a fluid called lymph). White blood cells are part of the immune system and are responsible for both directly and indirectly attacking foreign invaders of the body. Platelets: coagulating blood cells. Plasma: That 10 percent of the blood that contains nutrients, electrolytes (dissolved salts), gases, albumin, clotting factors, wastes, and hormones. Lymph: A transparent, slightly yellow fluid that carries lymphocytes. Lymph is derived from tissue fluids collected from all parts of the body and is returned to the blood via lymphatic vessels. deoxygenated blood: blood which contains very little oxygen.

9. circulatory questions 1)What is a heart attack? What causes it? 2)How is blood pressure measured? What is normal blood pressure? 3)What is hypertension? 1)A severe shortage of blood supply to the heart muscle. 2)You measured blood pressure with sphygmomanometer and normal blood pressure 120/80 mm Hg. 3)High blood pressure.
