active site - ✅✅-the part of an enzyme that is especially suited to bond with a

pituitary that acts on the adrenal glands to stimulate hormone release
, ✅✅-the blood vessel that enters the glomerulus
afferent arteriole -
afferent (sensory) neurons - ✅✅-the neurons that carry sensory information from
the body toward the central nervous system
aldosterone - ✅✅ -a hormone released by the adrenal cortex that induces sodium
reabsorption at the distal convoluted tubule of the nephron
