one cell thick
they connect arteries (from heart) to veins (to heart).
there are ALOT of them... every cell is within a few cells of one
capillaries
glomerulus
in the capillaries
capillaries
They have a thin basement membrane and an endothelial layer. The space between capillaries and gas in alveoli is very little.
Microcirulation consists of terminal arterioles connected to capillaries. The capillaries are connected to post-capillary venules which are connected to the veins,
The glomerulous
very thin, often a cell thick
Cartilages and epithelial cells
The structure of the malpighian body includes a network of capillaries surrounded by Bowman's capsule. This structure is adapted for ultrafiltration due to the small pores in the capillaries that allow small molecules to pass through while blocking larger ones, and the high pressure in the capillaries that forces fluid and solutes into Bowman's capsule.
