Explanation:
Detailed explanation-1: -Urea or BUN is a nitrogen-containing compound formed in the liver as the end product of protein metabolism and the urea cycle. About 85% of urea is eliminated via kidneys; the rest is excreted via the gastrointestinal (GI) tract.
Detailed explanation-2: -Urea enters the IMCD cell through UT-A1 and exits on the basolateral plasma membrane via UT-A3.
Detailed explanation-3: -The kidneys remove waste from the blood through tiny filtering units called nephrons. Each nephron is made up of a ball of small blood capillaries, called a glomerulus.
