Presented by D/Suzan Moustafa Hazzaa Professor of medical physiology Menoufia university The circulatory system is made up of the cardiovascular system and the lymphatic system. 1- heart : is the organ which pumps the blood. It is formed of : right and left atria (single = atrium) ………… atrio right and left ventricles (single = ventricle)…..ventriculo  Atrio-ventricular valves tricuspid Tri = three + cuspid Valve on the right side bicuspid Bi = two + cuspid Valve on the left side (mitral)  Semilunar valves Pulmonary valves Control the flow of blood to lung Aortic valves Control the flow of blood to aorta  Layers of the heart Epicardium outer layer myocardium muscular middle layer Endocardium inner layer The circulatory system is made up of five types of blood vessels that transport blood throughout the entire body: carry oxygenated blood from the heart to the different Arteries body parts Arterioles small blood vessels that connect the arteries to the capillaries capillaries smallest blood vessels where oxygenation and nutrients occur Venules small blood vessels that connect the capillaries to the veins veins carry deoxygenated blood from the different parts of the body to the heart  Diseases and disorders Myocarditis: inflammation of the myocardium (heart muscle) Endocarditis: inflammation of the endocardium Pericarditis: inflammation of the pericardium  Diagnosis Electrocardiogram electr/o + cardi/o + -gram measures the electrical activity of the heart electrocardiography: a noninvasive procedure used to record electrical activity of the heart electrocardiograph: record of the heart’s electrical activity  Diagnosis Echocardiogram echo + cardi/o + -gram record of the heart’s sonogram echocardiography: the use of sound waves to produce live images of the heart Cardiac a procedure in which a catheter is moved through a catheterization blood vessel to the heart to diagnose heart disorders D. suzan Hazzaa
