Pericytes stabilize the wall of capillaries.
do cappilaries have muscular walls
The name of the muscular wall is the myocardiumthey are called capillaries
capillaries
very thin, often a cell thick
Transitional arms
A dynamic structure that stabilizes cells lacking a cell wall (=animal cells). It consists out of microtubules, intermediate filaments and actin filaments.
Pulmonary capillaries
capillaries
intercellular clefts
Slow blood flow in the capillaries helps increase the efficiency of diffusion. The thin capillary wall also helps with diffusion.
The capillaries keep blood from leaking. They clot together quickly and keep as much blood inside the body as possible.
Your blood passes through the capillaries. Air goes to the alveoli. So both are separated by the wall of alveoli and the wall of capillaries. This wall is very thin but then tough enough to prevent such spill. The gases readily get transferred through this thin membrane.
