nephron

Glomerulus: Retains large molecules like proteins and blood cells.

Bowman's Capsule: Collects filtrate (water, ions, glucose) from the glomerulus.

Proximal Tubule: Reabsorbs glucose, amino acids, sodium, and water.

Descending Limb of Loop of Henle: Reabsorbs water; retains salt.

Ascending Limb of Loop of Henle: Reabsorbs salt; retains water.

Distal Tubule: Regulates pH, sodium, and potassium levels via hormonal control.

Collecting Duct: Reabsorbs water based on ADH levels to concentrate urine.
