Definitions:

Renin

An enzyme produced by the kidneys that plays a key role in regulating blood pressure by controlling the conversion of angiotensinogen to angiotensin I.

Juxtamedullary Nephrons

Specialized nephrons in the kidneys that play a crucial role in concentrating urine and are located near the boundary of the cortex and medulla.

Cortical Nephrons

Nephrons located in the kidney's cortex, characterized by shorter loops of Henle, playing a key role in filtering blood and urine formation.

Nephron Loops

The loop of Henle, a section of the nephron in the kidney that plays a crucial role in the concentration of urine and reabsorption of water and salts.
