The smallest blood vessels of the body = capillaries
Blood flows in capillaries, but there is blood leaks out from the capillaries, known as tissue fluid or interstitial fluid.
Pulmonary capillaries
capillaries
bronchus
The alveoli are surrounded by capillaries that carry carbon dioxide laden blood from the body and return oxygenated blood back to the body.
The smallest blood vessels are the capillaries.
Capillaries contain oxygenated blood.
Blood does not move faster through the capillaries. Blood flow is slowest in the capillaries.
Veins do not send blood to capillaries. They receive blood from capillaries. Arteries send blood to capillaries, in this case, specifically, hepatic arterioles.
Capillaries
Arterioles take blood from the arteries to the capillaries. Venules take blood from the capillaries to the veins.
