Capillaries are smallest in diameter blood vessels, connect to the smallest arterioles and the smallest venules. Capillaries are extentions of the inner linings of arterioles in that their walls are endothelium. These thin walls form the semipermeble layer through which substances are exchanged between the blood and the tissue fluid surrounding body cells.
A capillary connects arteries and veins. it is the site of diffusion of materials from cells to and from the bloodstream.

describe the function of the reproducive system
An organelle is a structure that is found within a cell and serves a specific function.
structureThe shape of the protein will determine the cell. It will also determine the function of the cell.
the cell's structure is based on what kind of function it's supposed to do.
Two ways in which the structure of a capillary is adapted to its function is to encourage the exchange of oxygen. Another reason is to encourage the exchange of carbon dioxide.

there is a aveolar wall, capillary wall, sqamous epithelium tissue, and blood inside the walls.
The function is to transport air to the rest of the body.

what funtion does the capillary loop have in the hair follicle
All organs have a different structure and function depending on what they are designated to do within the body.
Exchange
they are one cell thick.
capillary walls are very thin, often a cell thick. artery walls have two thick layers.
