Question

In the kidney, the high capillary bed is found in
A. In bowman’s capsule
B. Around anterior tubules
C. Around the loop of Henle
D. Absent

Answer 1

Hint: Generally, the capillary bed is the function of filtration of blood. so that it has a network-like structure .We have to think about the glomerulus because it is the main site of ultrafiltration, which is present in the bowman’s capsule.

Complete answer:
Bowman's capsule: At the proximal or closed-end the nephron is expanded and curved inwardly to form a double-walled cup-shaped Bowman's capsule. Within the Bowman's capsule, a network or tuft of capillaries is present, it is called Glomerulus. It is formed by the afferent arteriole la fine branch of Renal artery. Blood from the glomerulus is carried away by an efferent arteriole.

Malpighian body: Glomerulus and its surrounding Bowman's capsule together forms Malpighian body or Renal corpuscle. It is responsible for the first step of urine formation (Filtration). The outer wall of the Bowman's capsule is composed of flattened squamous cells. The inner, invaginated wall that lines the concavity of the Bowman's capsule is composed of a special type of cells called Podocytes. Which are arranged intricately to leave some minute spaces called filtration slits or slit pores. These cells are simple squamous cells and bear finger-like projections which are coiled around the capillaries of the glomerulus. The Bowman's capsule is followed by a short neck part lined by ciliated cuboidal epithelium.

Hence, the correct answer is option (A).

Note: Ultrafiltration process is carried out by glomerulus which is present in bowman’s capsule.so here the most capillary beds are found that’s why blood is filtrate here.
