ANATOMY

Detailed explanation-1: -The correct answer is option 3) i.e. Glomerulus. The glomerulus is a cluster of small blood vessels called capillaries located within Bowman’s capsule within the kidney.

Detailed explanation-2: -The glomerulus, the filtering unit of the kidney, is a specialized bundle of capillaries that are uniquely situated between two resistance vessels (Figure 1). These capillaries are each contained within the Bowman’s capsule and they are the only capillary beds in the body that are not surrounded by interstitial tissue.

Detailed explanation-3: -A nephron has two parts: a renal corpuscle and a renal tubule. The renal corpuscle consists of a cluster of capillaries, called the glomerulus, surrounded by a double-layered epithelial cup, called the glomerular capsule.

Detailed explanation-4: -Bowman’s capsule encloses a cluster of microscopic blood vessels-capillaries-called the glomerulus, where wastes are filtered from the blood.

Detailed explanation-5: -Fenestrated capillaries are especially important in your kidneys. They exist in and near the nephrons (the filtering units). You have about a million nephrons in each kidney. Inside each one is a bundle of fenestrated capillaries called a glomerulus.
