1. Filtration slits between podocytes

2. Basement membrane

3. Fenestrations in the wall of glomerulus

4. Renal tubules

Q.

The capillary epithelium, basement membrane, and podocytes together form the ______. There is a _________ charge fixed on the layers, which repels plasma components.

1. Filtration membrane and negative charge

2. Glomerulus and negative charge

3. Juxtamedullary Nephron and positive charge

4. Nephron and positive charge

Q. Which one of the following correctly explains the function of a specific part of a human nephron?

1. Afferent arteriole: carries the blood away from the glomerulus towards renal vein
2. Podocytes: Create minute spaces (slitpores) for the filtration of blood into the Bowman's capsule
3. Henle's loop: most reabsorption of the major substances from the glomerular filtrate
4. Distal convoluted tubule: re-absorption of $K^{+}$ ions into the surrounding blood capillaries

Q. There is a charge fixed on the layers, which repels plasma components.

1. positive
2. neutral
3. variable
4. negative
