H2 receptor
H2 Receptor
H2 receptor (pronounced as "H two receptor") is a type of protein that is found on the surface of certain cells in the body. It is part of the histamine receptor family and plays a crucial role in the regulation of gastric acid secretion.
Etymology
The term "H2 receptor" is derived from the word "Histamine", which is a compound that is involved in local immune responses, and the number "2" signifies that it is the second subtype of histamine receptors discovered.
Function
H2 receptors are primarily found in the stomach lining, where they stimulate the production of gastric acid. This acid helps in the digestion of food. The activation of H2 receptors also plays a role in the regulation of heart rate and smooth muscle relaxation.
