Kapillarwänden
Kapillarwänden refers to the walls of capillaries, which are the smallest blood vessels in the circulatory system. These incredibly thin structures are crucial for the exchange of substances between the blood and the surrounding tissues. The wall of a capillary is typically composed of a single layer of endothelial cells. This single-cell thickness is the key to their function, allowing for efficient diffusion of oxygen, carbon dioxide, nutrients, and waste products.
The endothelial cells that form the capillary walls are supported by a basement membrane, a thin layer
The structure of capillary walls can vary slightly depending on their location and specific function. For instance,
