Rush of blood

from Wikipedia, the free encyclopedia

The rush of blood , also called congestion (Latin congẹrere , “to accumulate”), refers to the increase in the amount of blood in certain areas of the body. Congestion can occur in the terminal vascular system (capillaries) mostly as a result of localized inflammatory stimuli or in severe hypertension or in the area of ​​the veins as a result of thrombosis or cardiac insufficiency . Also apply hormonal causes ( thyroid disease ) or physical effort than other causes.

A special form of the rush of blood is the erection of the penis , the clitoris and the swelling of the labia minora , in which the venous outflow is hindered by the arterial pressure and thus the pressure in the erectile tissue increases .
