Human Physiology Chap.10 Blood Vessels & Blood Pressure PAH 0 I. Introduction a) Blood F low, P ressure and R esistance b) F= ^P/R R -Factors i.e. - length of vessel, longer vessel adds more drag - diameter or Radius of vessel= r 4 - viscosity of blood, i.e. polycythemia. . II. Arteries =because of walls, act as pressure reservoirs a) Pressure i.e 120/80 mm Hg and other levels Say, 95/60= 138/90= 140/ or /90 150/90= b) M ean A rterial P ressure and its significance Pulse Pressure==>number Pressure Pulse--look strange? Factors1. 2. 3. III.Arterioles a) Site of Resistance/Control why ? 1. 2. 3. Other Interactions via arterioles 1. 2. 3. 4. b) Vessel Radius and Extrinsic Control (i.e. sympathetic NS) IV. Capillaries: handout - the numbers offered here are relative, but good for comparison work. Capillaries are sites of (real) exchange for tissues. a) Sites of Exchange b) Diffusion c) Bulk Flow d) Lymphatic System Link e) Edema--Possible causes
