Renal corpuscle

Renal tubule

Secretion of ions, acids, drugs, toxins Variable reabsorption of water sodium ions, and calcium ions (under hormonal control)

Thick ascending limb

Thin descending limb

Variable reabsorption of water and reabsorption or secretion of sodium, potassium, hydrogen, and bicarbonate ions
