Capillaries have thin walls so that oxygen, carbon dioxide, nutrients and waste can flow through the walls without difficulty.

Hope this helps!

Answer from: kevinbazalar

Capillaries need to be thin-walled to exchange the gases and nutrients in blood and tissue.

Further Explanation:

Capillaries are considered to be very small. They link the arteries and veins to transport essential nutrients and substances between the blood and tissues. The blood circulating through the capillaries get diffused into the tissues, due to their thin walls, and this fluid forms the interstitial fluid. The plasma proteins being heavier do not cross the membrane, and only the water along with solutes diffuses out. The interstitial fluid will return to the capillaries by the lymphatic system, which drains it into subclavian veins.

The maximum part of the fluid is returned to the circulatory system, and some parts of that fluid are drained into veins. The lymphatic system connects with the subclavian veins that are part of the circulatory system and connect to the heart. The interstitial fluid from the tissue is transported back to the heart by lymphatic capillaries. Kidney, liver, and muscle consist of numerous numbers of capillaries to transport essential substances across the blood and tissue.
