Detailed explanation-1: -The term glomerulus, often used to imply the renal corpuscle, is a knot of capillaries that links the afferent and efferent arterioles within the renal corpuscle. These unusual capillaries receive blood at relatively high pressure (70 mmHg), and are both fed and drained by arterioles.
Detailed explanation-2: -The glomerulus is a tuft of capillaries located within Bowman’s capsule within the kidney. Glomerular mesangial cells structurally support the tufts. Blood enters the capillaries of the glomerulus by a single arteriole called an afferent arteriole and leaves by an efferent arteriole.
Detailed explanation-3: -The renal corpuscle is the filtering portion of the nephron; it is made up of a ball of capillaries called the glomerulus and a glomerular capsule that receives the filtrate.
