Your blood pressure is dangerously low, making you feel dizzy. Let’s see how much you can teach me back about RAAS homeostasis. 1) The Renin-Angiotensin-Aldosterone System (RAAS) is a complex system of hormones, proteins, enzymes, and reactions that help increase and blood volume in the body. 2) The process starts with the   releasing an enzyme called renin, which converts angiotensinogen to angiotensin I.  3) The lungs convert angiotensin I to angiotensin II using the enzyme , which causes and helps maintain vascular tone. 4) The in turn, triggers aldosterone release from the adrenal glands, leading to increased reabsorption. Since water solutes, the body holds more water to maintain the blood pressure!! 5) Additionally, the posterior pituitary gland releases to aid in water reabsorption via the kidneys again, and makes you thirsty to drink water!! Isn’t this amazing to learn? What do you say!!
