WebA capillary is a microscopic channel that supplies blood to the tissues, a process called perfusion. Exchange of gases and other substances occurs between the blood in capillaries and the surrounding cells and their tissue fluid (interstitial fluid). WebThe capillary wall is a one-layer tissue so thin that gas and other items (eg oxygen, water, proteins and fats) can pass through them driven by pressure differences. Waste items such as carbon dioxide and urea can move back into the blood to be carried away for removal from the body. The Capillary Bed: Capillaries do not function independently.
