Question

Describe in brief how urine is produced in the human body.

Answer 1

Blood enters the kidneys through the renal artery, which branches into many capillaries associated with the glomerulus. Water and other solutes are transferred at the Bowman’s capsule. In the proximal tubule, some substances such as amino acids, glucose, and salts are selectively re-absorbed and unwanted molecules are removed. In the loop of Henle, water is re-absorbed. From here, the filtrate moves upwards into the distal tubule, and on to the collecting duct. This duct collects urine from many nephrons.
