Study Notes
Hyperemia and Congestion
- Hyperemia is an active process involving arteriolar dilation, leading to increased blood flow.
- In hyperemia, affected tissues turn red (erythema) due to increased delivery of oxygenated blood.
- Congestion is a passive process resulting from reduced venous outflow of blood from a specific area.
- Congested tissues exhibit an abnormal blue-red color (cyanosis) due to the accumulation of reduced hemoglobin in the affected area.
- Long-standing chronic passive congestion can lead to ischemic tissue injury and scarring due to associated chronic hypoxia.
- Chronic passive congestion can cause capillary rupture, leading to hemorrhage and edema in affected tissues.
