Histamine
A) Lipids that cause smooth muscle relaxation and vasodilation
B) Lymph nodules aggregated in the small intestinal wall

D) Areas of a lymph node where lymphocytes divide
E) A chemical released from mast cells that causes vasodilation
Histamine
An organic nitrogenous compound involved in local immune responses, regulating physiological function in the gut, and acting as a neurotransmitter.
Vasodilation
The widening of blood vessels, which decreases blood pressure and allows for increased blood flow.
Smooth Muscle Relaxation
The process by which smooth muscles (found in the walls of internal organs and blood vessels) relax, leading to dilation of blood vessels and decreased resistance to blood flow.
