Question

What are the functions of a nephron???​

Answer 1

A nephron is the basic structural and functional unit of the kidneys that regulates water and soluble substances in the blood by filtering the blood, reabsorbing what is needed, and excreting the rest as urine. Its function is vital for homeostasis of blood volume, blood pressure, and plasma osmolarity.

$\Large\star\sf\underline\pink{About\:Nephron}$

Nephrons are the basic filtering units of Kidneys. Each kidney possesses large number of nephrons approximately 1 to 1.5 million. The main components of the nephron are glomerulus, Bowman's capsule and a long renal tubule.

$\Large\star\sf\underline\green{Functions\:of\:a\:Nephron}$

• The blood enters the kidney through the renal artery which branches into many capillaries associated with glomerulus.

• The water and solute are transferred to the nephron at bowman's capsule. In the proximal tubule some substances such as amino acids, glucose and salts are selectively reabsorbed and unwanted molecules are added in the urine.

• The filtrate then moves down into the loop of Henle, where more water is absorbed.

• From here the filtrate moves upwards into the distal tubule and finally to the collecting duct.

• Collecting duct collects urine from many nephrons.
