Document Summary
Circulation and blood flow movement of fluid . How the fluids and nutrients get circulated within the body. Distribution of water between intracellular and extracellular compartments. Intake 1. 5l-2. 5l of water per day via gi tract (food + drink) The majority is absorbed into interstitial fluid (11-13l) Interstitial fluid can enter cells (intracellular) via pressure gradient (27-30l) Water is excreted by the kidneys (0. 6-1. 5l) Water is excreted by lungs in the form of humidity (0. 3-0. 4l) Water is excreted by the skin in the form of sweat (0. 2-1l) Water is excreted by gi tract in the form of feces (0. 1-0. 2l) Exchange takes place within the capillaries beds. Arteries and veins are almost always in proximity to one another. Skeletal muscle milks blood in veins toward the heart. The cardiovascular system has three types of blood vessels. Arteries (and arterioles) carry blood away from the heart, fed by the aorta. Capillaries where nutrient and gas exchange happens between plasma and ecf.
