One of the minute blood vessels that convey blood from the arterioles to the venules and form an anastomosing network that brings the blood into intimate relationship with the tissue cells. Its wall consists of a single layer of squamous cells (endothelium) through which oxygen diffuses to the tissue and products of metabolic activity enter the bloodstream. Blood capillaries average about 8 μm in diameter.
A thin-walled lymphatic vessel at the beginning of a branch of the lymphatic system. Lymphatic capillaries have closed ends, but have no basement membranes and are more permeable than blood capillaries. Fluids, salts, proteins, large molecules, particles, debris, microorganisms, and migrating cells can pass from the interstitial spaces into lymphatic capillaries. Lymphatic capillaries lead to larger lymphatics that transport the lymph to lymph nodes. See: illustration
