Question

Filtration slits or slit pores are spaces maintained by

• A. Henle's loop
• B. Proximal convoluted tubule
• C. Podocytes
• D. Collecting duct

Answer 1

The correct option is C

Podocytes

The correct option is C.

Explanation of the correct option:

1. Bowman's capsule contains epithelial cells called Podocytes.
2. Filtration slits, also known as slit pores, are created by arranging them in an elaborate pattern.
3. All plasma elements except protein pass into the Bowman's capsule because blood is filtered so finely through these pores.
4. This filtration method is known as ultrafiltration.

Explanation of the incorrect options:

Option A:

1. In reptiles, birds, and mammals, the loop of Henle is a long U-shaped section of the tubule that transports urine within each nephron of the kidney.
2. The primary purpose of the Henle loop is to recover water and sodium chloride from urine.

Option B:

1. Between Bowman's capsule and the loop of Henle, the convoluted section of the vertebrate nephron acts primarily in the resorption of sucrose, sodium, and chloride ions, and water from the glomerular filtrate.

Option D:

1. The kidney's collecting duct system is made up of tubules and ducts that physically connect nephrons to either a minor calyx or the renal pelvis.

Final answer: Filtration slits or slit pores are spaces maintained by podocytes.
