\(\mathrm{Na}^{+}\)is reabsorbed in the PCT of a nephron by
1 Diffusion
2 Osmosis
3 Endocytosis
4 Active transport
Explanation:
Substances like glucose, amino acids, \(\mathrm{Na}^{+}\), etc., in the filtrate are reabsorbed actively whereas the nitrogenous wastes are absorbed by passive transport.

Which of the following is an incorrect statement about filtration?
1 Selective process
2 Non-selective process
3 Performed by glomerulus
4 It occurs through the usage of capillary (glomerulus) blood pressure
Explanation:
Glomerular filtration depends on the effective pore size and glomerular hydrostatic pressure. The filtration membrane is not selective and filters everything in the blood except corpuscles and large blood proteins.

The given diagram shows the reabsorption and secretion process of urine formation. Which molecules are actively reabsorbed in tubular segments?
1 Nitrogenous wastes
2 Water
3 Glucose, amino acids, \(\mathrm{Na}^{+}\)
4 Both 1 and 3
Explanation:
The tubular epithelial cells in different segments of nephron perform reabsorption either by active or passive mechanisms. Substances like glucose, amino acids, \(\mathrm{Na}^{+}\), etc., in the filtrate are reabsorbed actively.

In human beings, the blood passing through which of the following blood vessels has maximum concentration of urea?
1 Renal vein
2 Renal artery
3 Hepatic portal vein
4 Hepatic vein
Explanation:
Urea is synthesised in the liver. Hepatic vein drains blood from the liver into the inferior vena cava. So, concentration of urea is maximum in the blood passing through the hepatic veins. Concentration of urea is least in the blood passing through renal veins which drain blood from kidneys into the inferior vena cava.

Main function of Distal Convoluted Tubule (DCT) of nephron is to maitain the
1 \(\mathrm{pH}\) in blood
2 Na-K balance of blood
3 Temperature of blood
4 1 and 2
Explanation:
Conditional reabsorption of \(\mathrm{Na}^{+}\)and water takes place in DCT. It is also capable of reabsorption of \(\mathrm{HCO}_{3}^{-}\)and selective secretion of hydrogen and potassium ions and \(\mathrm{NH}_{3}\) to maintain the \(\mathrm{pH}\) and sodium-potassium balance in blood.
