Physiology of Urine Formation

Definition

The physiology of urine formation is the process by which the kidneys filter blood, remove waste, and regulate fluid balance in the body to produce urine. It involves several steps including filtration, reabsorption, secretion, and excretion.

Tubular Secretion: The transfer of materials from blood into the filtrate anywhere other than the glomerulus to be excreted as urine
