Malpighian corpuscle

Malpighian Corpuscle

The Malpighian corpuscle, also known as the renal corpuscle, is a crucial component of the nephron, the functional unit of the kidney. It is named after the Italian physician and anatomist Marcello Malpighi who first described it.

Structure

The Malpighian corpuscle consists of two main parts: the glomerulus and the Bowman's capsule. The glomerulus is a network of tiny blood vessels, or capillaries, while the Bowman's capsule is a cup-like sac that surrounds the glomerulus.

Function

The primary function of the Malpighian corpuscle is to filter blood. Blood enters the glomerulus under high pressure, causing water, glucose, salts, and waste products to be forced out of the blood and into the Bowman's capsule. This process is known as glomerular filtration. The filtered substances then pass into the renal tubule, where they are either reabsorbed into the blood or excreted as urine.

Clinical significance

Damage to the Malpighian corpuscles can lead to various kidney diseases, such as glomerulonephritis and diabetic nephropathy. These conditions can impair the kidney's ability to filter blood, leading to a buildup of waste products in the body.
