Hyperemia mechanism
Hyperemia mechanism
Hyperemia is an active process driven by arteriolar dilation, increasing blood flow to tissues.
Hyperemia tissue color

Study Notes
Hyperemia
- Active process with increased blood flow to tissue
- Increased arteriolar dilation
- Tissues appear red due to increased oxygenated blood delivery
Congestion
- Passive process with reduced venous outflow from tissue
- Tissues appear blue-red (cyanosis) due to accumulated deoxygenated hemoglobin
- Can lead to chronic hypoxia, ischemic tissue injury, and scarring
Differences between Hyperemia and Congestion
- Hyperemia is an active process, while congestion is a passive process
- Hyperemia results in an increased blood flow to tissue, while congestion is a result of the accumulation of blood in a tissue due to reduced venous outflow
- Hyperemia causes a reddening of the tissue, while congestion causes a blue-red discoloration (cyanosis)
