Definition of Capilary Beds
Arterial pressure forces blood into the capillary beds. Erythrocytes (red blood cells) carry oxygen and other nutrients to the capillary beds, where these molecules pass through to cells.
Correspondingly, the cells pass metabolic waste such as carbon dioxide and lactic acid through to the blood. The arterioles and the venules intertwine in the capillary beds, becoming indistinguishable.
