BLOOD TYPES THE LYMPHATIC SYSTEM CIRCULATORY SYSTEM contd. MAJOR CONCEPTS 1. In human beings, the blood, kept in motion by the pumping of the heart circulates through the vessels. 2. The heart is actually a double pump: the right side pumps blood to the lungs and the left to the rest of the body CIRCULATION contd. 3.Body cells are nourished by the blood when exchange of molecules takes place across the thin walls of the capillaries. 4. While the circulatory system is very efficient, it is still subject to various degenerative illnesses, most of which can be prevented or alleviated by CIRCULATION contd. 5. Blood, which is composed of cells and a fluid matrix called plasma contains many organic and inorganic molecules. 6. Blood has three primary functions: (a) transport (b) clotting © fighting infection 7. Blood transports nutrients to and waste from the tissues. CIRCULATION contd. 8. The process of clotting requires a complicated series of reactions aided by the thrombocytes and normally preventing the loss of blood after injury. 9. White cells, some of which phagocytize invading microbes CIRCULATION contd. And gamma globulins which combine with foreign proteins (antigens) , in a specific manner, are the body’s defense against infection and disease. CIRCULATORY SYSTEM & VESSELS (NEXT SLIDE) CIRCULATION contd. SYSTEM AND VESSELS A. Circulatory System 1. Cardiovascular system (a) heart & blood vessels 2. Lymphatic system B. VESSELS 1. Veins (smallest-venules) blood to heart CIRCULATION contd. Arteries (smallest-arterioles) Capillaries (1 cell layer in thickness) VEINS & ARTERIES-3 tunics (innermost - endothelium) Arteries are “muscular” & elastic CIRCULATION contd. THE HEART A double pump with 4 chambers and 4 valves. The right & left sides of the heart are divided by the intraventricular septum. The valves prevent the blood from flowing backwards. Their opening and closing make the “lup a dup” sound during heart CIRCULATION contd. THE HEART (CONTD.) 1. Terms associated with the valves. 2. Primarily muscle (STRIATED MUSCLE) Myocardium 3Three Layered (pericardium; myocardium; endocardium Furnished with oxygen & nutrients by coronary artery CIRCULATION contd.
