Document Summary
Capillaries are so good at allowing the change for materials the reason is that is the morphology. The fact that they have very thin walls and packed close to the cells, they are trying to get the nutrients and gasses to. They are in the right location and they don"t offer a large barrier for diffusion. This graph shows what makes capillaries even more ideal for allowing exachange. It has to do with what happens to blood velovity aas the blood transit through the capailliares. The blood flow is not the same blood velocity. Blood flow= is volume per min or time (v/min) Velocity = is distance per time (distance/ time ) gives no concept of vol , only distance measurement. Since there are so many millions of capillaries, they represent a vast cross-sectional area in the circulatory system. The pic shows large aorta arteries to capillaries to the veins .
