The Urinary System

The urinary system contributes to homeostasis and the kidneys are the primary regulators or water balance and most excess solutes , especially inorganic ions and urea.

The system consists of organs that produce, transport, store, and excrete urine.

Nephrons in the kidneys produce urine and each nephron consists of tubular components and blood vessels that supply.

The tubular components of a nephron are the glomerular capsule, proximal tube, loop of Henle, distal tube, and collecting duct.

The formation of urine involve three processes which are glomerular filtration, tubular reabsorption, and tubular secretion.
