Facts about Function of Kidney Nephrons
- 05
Distal convoluted tubules in nephrons regulate blood pH and electrolyte balance by secreting hydrogen and potassium ions into the filtrate.
- 04
Proximal convoluted tubules in nephrons reabsorb the majority of filtered glucose, amino acids, and water back into the bloodstream before urine is finalized.
- 03
Glomerular filtration, the first step performed by nephrons, forces water, salts, and small molecules out of the blood at high pressure into the Bowman's capsule.
- 02
The loop of Henle, a key segment of the nephron, creates a concentration gradient in the kidney medulla that enables water reabsorption and urine concentration.
- 01
Each human kidney contains approximately one million nephrons, which filter blood to produce urine through processes of filtration, reabsorption, and secretion.
