Question

list two major steps involved in the formation of urine and state in brief their functions

Answer 1

The renal artery brings in urea rich blood into the glomorulus which are a bundle of blood capillaries. Blood gets filtered as it passes through the glomorulus. Glucose, amino acid, urea, salts and water passes through the bowman’s Capsule and enter the tubule.
The filtrate as it passes through the tubule , the useful substances like amino acids, glucose, Mostafa salts and water gets reabsorbed by the blood capillaries that surround the tubule. Reabsorption because the filtrate contains useful subs. If these are excreted out then the body will lose large amounts of useful subs.
The liquid left behind after reabsorption is urine.
