Question

The filtration slits are formed in the Bowman’s capsule by ________.

• (A) Henle loop
• (B) Glomerular blood vessel
• (C) Podocytes
• (D) Nerve endings

Answer 1

The Correct Option is C

Explanation:
The filtration slits are formed in the Bowman’s capsule by podocytes.The nephron has two parts: Glomerulus & the renal tubule. The glomerulus is a tuft of capillaries formed by the afferent arteriole – a fine branch of the renal artery. It is enclosed by a double-wall structure called the Bowman's capsule. The Glomerulus along with the bowman's capsule performs the function of filtration of blood. The blood gets filtered through 3 layers, i.e., the endothelium of glomerular blood vessels, the epithelium of Bowman’s capsule, and a basement membrane between these two layers.The epithelial cells of Bowman’s capsule called podocytes are arranged in an intricate manner so as to leave some minute spaces called filtration slits or slit pores. Blood is filtered so finely through these membranes, that almost all the constituents of the plasma except the proteins pass onto the lumen of the Bowman’s capsule. Therefore, it is considered a process of ultrafiltration.Thus, filtration slits are formed by the podocyte cells of the Bowman's capsule.Hence, the correct option is (C).
