MICROANATOMY

Detailed explanation-1: -The nephrons work through a two-step process: the glomerulus filters your blood, and the tubule returns needed substances to your blood and removes wastes. Each nephron has a glomerulus to filter your blood and a tubule that returns needed substances to your blood and pulls out additional wastes.

Detailed explanation-2: -Each kidney contains about one million tiny units called nephrons. Each nephron is made up of a very small filter, called a glomerulus, which is attached to a tubule. As blood passes through the nephron, fluid and waste products are filtered out.

Detailed explanation-3: -The nephron uses four mechanisms to convert blood into urine: filtration, reabsorption, secretion, and excretion.

Detailed explanation-4: -It helps in the recovery of water and sodium chloride from the urine. It helps in the conservation of urine.
