Question

Quizplus · Accepted Answer

Leukotrienes are known as SRS-As (slow-reacting substances of anaphylaxis) and are released by mast cells and other cells in response to allergens or tissue injury. They promote bronchoconstriction, increased vascular permeability, and mucus secretion, among other effects. They generally have slower and more sustained effects compared to histamines.
