APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Each of your kidneys is made up of about a million filtering units called nephrons. Each nephron includes a filter, called the glomerulus, and a tubule. 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.

Detailed explanation-2: -The nephron functions through ultrafiltration. Ultrafiltration occurs when blood pressure forces water and other small molecules through tiny gaps in capillary walls. This substance, lacking the blood cells and large molecules in the bloodstream, is known as an ultrafiltrate.

Detailed explanation-3: -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-4: -The nephron uses four mechanisms to convert blood into urine: filtration, reabsorption, secretion, and excretion.
