Document Summary

Ensures oxygen and nutrients are delivered to all of the cells in the body. Consists of: heart (which is a muscular pump) cardio , blood vessels (fuel line and transportation network) vascular . Do a lot more than just carry blood! Thick walled vessel (muscular layer because has to withstand pressure from blood pumping from heart, elastic layer so it can expand) Usually carries oxygen rich blood (there are exceptions opposite for pulmonary) Smaller branches are called arterioles: capillaries. Smallest vessels (1 endothelial cell in thickness) Carry oxygen/nutrient rich blood to body cells! Thins walls allow for passage of oxygen and nutrients into cells. Only point of exchange for oxygen and nutrients into body cells and waste filled blood with co2 and water coming from body cells flows back into heart through venules: veins. Thin walled vessels (thinner muscular wall because farther from heart than arteries) Usually carries oxygen poor blood (there are exceptions opposite for pulmonary)
