the lmyphic system absourds it and give it back to the heart.
capillaries
Capillaries
The fluids in the blood leak through the capillaries and into the surrounding tissue. After the cells are bathed the fluid moves into the the lymphatic system. It is then returned into the bloodstream
Blood flows in capillaries, but there is blood leaks out from the capillaries, known as tissue fluid or interstitial fluid.
In the alveoli
If lymph iis not pushed through a lymphatic vessel, it will leak back out of the lymphatic capillaries. When this happens, swelling of th surrounding tissue occurs. This condition is called Edema.
Once oxygenated blood reaches the capillaries, the velocity of the blood is very slow - which favours the exchange of oxygen. Oxygen therefore diffuses across the walls of the capillaries into the tissues that need it.
Capillaries are the connection between arterioles and venules. The capillaries job is to enable the exchange of oxygen, water, carbon-dioxide, chemical substances and various nutrients to between blood and the surrounding tissue.
Tissue without capillaries is called avascular tissue. Examples of avascular tissue include:CartilageEpitheliaCorneaLensAll organs contain blood vessels.
Capillaries
Arteries carry blood to the tissues, and veins carry blood back to the heart. In betweenare tiny blood vessels so small that red blood cells can pass through single file, allowingthe oxygen to diffuse into the surrounding tissue. These are called capillaries.
This tissue is simple squamous, a type of epithelium. It is the thinnest tissue, one cell thick, since gases are exchanged in the aleoli and capillaries surrounding them.
