Angiotensin is a term used in the field of medicine and biology. It is a hormone that plays a crucial role in regulating blood pressure and fluid balance in the body. This article will provide a comprehensive overview of the definition, origin, meaning, associations, synonyms, antonyms, and example sentences of angiotensin.
Definitions
Angiotensin is a peptide hormone that constricts blood vessels, thereby increasing blood pressure. It is produced by the renin-angiotensin system, which is a complex system that regulates blood pressure and fluid balance in the body. Angiotensin is also involved in the regulation of electrolyte balance and the release of aldosterone, another hormone that affects blood pressure.
Origin
The term angiotensin comes from the Greek words “angeion” meaning vessel and “tension” meaning pressure. The hormone was first discovered in 1939 by a team of scientists led by Irvine Page at the Cleveland Clinic.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, angiotensin is defined as “any of several polypeptides (such as angiotensin I, angiotensin II) that are vasoconstrictive and increase blood pressure.” The Oxford English Dictionary defines angiotensin as “a hormone that constricts blood vessels, increasing blood pressure.”
Associations
Angiotensin is associated with several medical conditions, including hypertension (high blood pressure), heart failure, and kidney disease. It is also a target for several medications used to treat these conditions, such as ACE inhibitors and angiotensin receptor blockers.
Synonyms
Some synonyms of angiotensin include:
- Renin-angiotensin system.
