What is the role of the juxtaglomerular apparatus in renal physiology?

Step 1: Understand that the juxtaglomerular apparatus (JGA) is a structure in the kidney.
Step 2: Know that the JGA is located near the glomerulus, which is a network of tiny blood vessels in the kidney.
Step 3: Learn that the JGA has special cells that can sense blood pressure and blood flow.
Step 4: Recognize that when blood pressure is low, the JGA releases a hormone called renin.
Step 5: Understand that renin helps to increase blood pressure by causing blood vessels to constrict and by helping the body retain water and salt.
Step 6: Conclude that the JGA helps regulate both blood flow to the glomerulus and overall blood pressure in the body.
