CONGESTION

When there is an unnatural accumulation of blood in the capillary ve els of any part of the sanguiferous system, the organ in which it takes place, and the functions of wliich are disturbed, is said to suffer under congestion: it induces a morbid condition of the ve els of the part affected, which when once established is difficult of removal. Congestion of the brain, liver, or lungs is a frequent effect of fevers, though generally consequent upon a previous morbid condition of the organs. [s. 284]
