Circulatory system is closed system exept at cappilory level. Here fluid leks out at proximal end of capillaries. It carries with it oxygen and digested food materials, disolved in plasma except plasma proteins. They are supplied to tissue cells and in return you get the carbon bi oxide and wasre products of metabolism. They reenters the circulation at distal end of capillary. At proximal end of cappilary, you have about 30 mm of Mercury blood pressure and at distal end it is about 20 mm of mercury. Fluid is pulled back due to oncotic pressure of plasma proteins.

What functions do the capillaries do in the cardiovascular system?
They enable the exchange of water, oxygen, carbon dioxide, and many other nutrient and waste chemical substances and between blood and surrounding tissues.
Why must complex muticellular organisms have transport systems?
Large organisms need transport systems to supply all their cells with food, oxygen and other materials.Multi-cellular organisms are too big and not all of their cells have contact with the external environment. All organisms need to exchange substances with their environment - take in needed molecules and get rid of waste. A uni-cellular organism can use the processes of osmosis, diffusion and active transport to transport substances in and out of the organism, which is in this case just one cell. But as organisms increase in size, they need a specialized transport system to exchange substances between the internal environment and the external environment. Interestingly enough, osmosis and diffusion are still the important mechanisms at the cellular level.
What is the explanation for the process of capillary exchange?
Capillary exchange is the process by which substances, such as oxygen and nutrients, are exchanged between the blood in capillaries and the surrounding tissues. This occurs through diffusion, facilitated diffusion, and active transport. The exchange is driven by a concentration gradient and the movement of substances across the capillary wall is regulated by small pores called fenestrations and by the presence of transport proteins.
