Capillary Anatomy

As their name suggests continuous capillaries have a continuous endothelial lining. Most capillaries are 3 to 4 µm micrometers in diameter.

Capillaries are most abundant in tissues and organs that are metabolically active.

Capillary anatomy. It is through the capillaries that oxygen nutrients and wastes are exchanged between the blood and the tissues. A capillary is an extremely small blood vessel located within the tissues of the body that transports blood from arteries to veins. The average diameter of a capillary is 68 micron just sufficient to permit the red blood cells to pass through in single file.

These microvessels are the site of exchange of many substances with the interstitial fluid surrounding them. These capillaries can be found in tissues where a large amount. Capillary in human physiology any of the minute blood vessels that form networks throughout the bodily tissues.

Substances which exit include water proximal portion oxygen and glucose. As arteries branch and divide into arterioles and continue to reduce in size as they reach the muscle they become capillaries. It is smallest in the brain and intestines and largest in the skin and bone marrow.

Capillaries are the smallest of all blood vessels and form the connection between veins and arteries. But the size varies from organ to organ. Substances which enter include water distal portion carbon dioxide uric acid lactic acid urea and creatinine.
