Document Summary
Blood low is lowest in the capillaries (larger surface area) Total peripheral resistance resistance blood vessels give against low in cv system. In co2 and h+ ions (both blood low) Create more co2 to be able to decrease oxygen intake. Local factors determine if muscular bed is open or not. 15-20% of cardiac output goes to skeletal muscles at rest. During heavy exercise, capillary beds open up. Fireighter heaing up, can do less exercise. Best thing is to lower core temperature before exercising (for prolonging it) Set point criical temperature where exercise stops. 3 major physiological responses that occur when you go for a run sweat, hr , breathing becomes more laboured. 55% is plasma, 45% erythrocytes, <1% formed elements. If iron deicient, less binding sites for oxygen. For each mmhg of po2 0. 03ml of o2 dissolved/l blood (henry"s law) Total o2 per l of arterial blood = 217ml.
