Question

tubular reabsorption mostly occurs in which portion of the nephron?
a distal convoluted tubule
b proximal convoluted tubule
c collecting duct
d bowmans capsule
question 44
which of the following is the maximum amount of air that can be inhaled after a maximum exhalation?

Explanation:

Tubular reabsorption is a crucial process in the nephron. The proximal convoluted tubule has a large surface area due to its brush - border epithelium. It reabsorbs a large percentage of filtered substances such as glucose, amino acids, most of the water, and electrolytes. The distal convoluted tubule and collecting duct have more specialized reabsorption functions (e.g., fine - tuning of electrolyte and water balance based on hormonal signals). Bowman's capsule is mainly involved in filtration, not reabsorption.

Answer:

B. Proximal convoluted tubule
