Chapter 14, Problem 18RA
Summary Introduction
To determine:
Angiotensin is responsible for which of the following.
Introduction:
Angiotensin is a peptide hormone, which can increase blood pressure and vasoconstriction. It is also used to regulate the blood pressure and stimulate aldosterone. It is produced by the liver cells.
