Study Notes
Capillary Characteristics
- The approximate diameter of capillaries is 5-10 micrometers.
- Capillaries contain a single layer of endothelial cells.
Blood Vessels and Blood Type
- Smaller veins and arteries, arterioles, and venules contain oxygenated blood.
Pericytes in Capillaries
- The function of pericytes in capillaries is to provide mechanical support and regulate blood flow.
Blood Flow
- Blood from capillary beds flows into venules.
Inflammation Pathophysiology
- In most forms of inflammation, vascular leakage and leukocyte exudation occur preferentially in postcapillary venules.
