Kidney nephron jobs

What is a nephron?

The nephron is the functional unit of the kidney responsible for filtering blood and forming urine.

Glomerulus function

Filters blood to produce filtrate, which contains water, salts, and waste.

True or false: Nephrons can regenerate.

False, because nephrons do not have the ability to regenerate once damaged.

Role of Bowman's capsule

Surrounds the glomerulus and collects the filtrate from blood filtration.

Difference between proximal and distal tubules

Proximal tubule reabsorbs nutrients, while distal tubule regulates electrolyte balance.

What is reabsorption?

The process where the nephron returns necessary substances from filtrate back into the bloodstream.

Function of loop of Henle

Concentrates urine by reabsorbing water and sodium, creating a gradient in the medulla.

Fill in the blank: The nephron ends at the ______.

Collecting duct, where final urine concentration occurs before excretion.

What does ADH do?

Antidiuretic hormone increases water reabsorption in the collecting ducts, reducing urine output.

True or false: Nephrons regulate blood pH.

True, because they can excrete or reabsorb hydrogen and bicarbonate ions.

What is secretion in the nephron?

The process where waste products are transferred from blood into the nephron tubule.

Role of collecting ducts

Final site for water reabsorption and urine concentration before it enters the ureter.
