What are effects of histamines on the vasculature?
Histamines play a significant role in the vasculature by causing vasodilation and increasing vascular permeability. When released during allergic reactions or inflammatory responses, histamines bind to H1 receptors on endothelial cells, leading to the relaxation of smooth muscle and widening of blood vessels. This results in increased blood flow to the affected area and allows immune cells and fluids to leak into surrounding tissues, contributing to symptoms like swelling and redness. However, excessive histamine release can lead to conditions such as anaphylaxis, characterized by severe hypotension and shock.

Symptoms may include itching, swelling, redness, and increased blood flow to the affected area.
