Study Notes
Blood Vessel Characteristics
- Small arteries and arterioles within tissues and organs have a diameter range of 10-100 μm.
Capillary Function
- The main function of capillaries is to facilitate the exchange of substances between blood and tissues through diffusion and osmotic pressure.
Vessel Density
- Arterioles have the highest density in tissues with high metabolic rates, such as the myocardium and brain, due to their high oxygen demands.
Blood Flow
- Blood from capillary beds flows into venules.
Inflammation
- Vascular leakage and leukocyte exudation occur preferentially in post-capillary venules during most forms of inflammation.
