Functions of nephron
Answers
Answer:
A nephron is used separate to water, ions and small molecules from the blood, filter out wastes and toxins, and return needed molecules to the blood. The nephron functions through ultrafiltration.
Explanation:
Nephrons function :
1.Filtration:the renal artery or afferent artery is wider and slowly it becomes a narrow tube in glamerulus.Due to difference in the width,pressure difference is caused and water with dissolved impurities are squeezed out of Bowman's capsule which is cup like structure and passes into the tube
2.Reobsorbtion:the filtrate passes through tubule where major amount of water, glucose,amino acids are selectively reabsorbed by capillaries which are surrounding the tubule.
3.Urin formation:the water and impurities which in not reabsorbed is sent to collecting duct. this filtrate contains more of dissolved nitrogenous wastes i.e urea and hence it is termed as urine.from here the urin enters the ureters and is collected in urinary bladder
