Renin-Angiotensin-Aldosterone System (RAAS)
Overview
The Renin-Angiotensin-Aldosterone System (RAAS) system is a complex, interconnected pathway that uses multiple hormones and cell types, primarily centered in the kidney, to tightly regulate and maintain healthy blood pressure levels in the body.
Learning Objectives
By the end of this chapter, students will be able to:
- define the Renin-Angiotensin-Aldosterone System.
- describe the purpose for the RAAS.
- name the triggers for the kidneys to secrete renin.
- explain the process by which angiotensinogen is ultimately converted to Angiotensin II.
- explain how the pituitary gland, kidneys, and adrenal glands function to increase blood pressure.
