Answer 2

The function of this network is (iv) a, b, d- reabsorption of water, sodium, and food nutrients.

• The red colored tubular network is the blood capillaries surrounding the tubule of a nephron in kidney.
• Blood filtration occurs at the glomerulus level.
• The procedure that removes solutes and water from the filtrate and returns them to your bloodstream is known as tubular reabsorption.
• Reabsorption refers to the fact that this is their second absorption, the first being when they entered the bloodstream from the digestive tract following a meal.
• Sodium bicarbonate and sodium chloride make up the majority of the solutes reabsorbed in the proximal tubule, where roughly 70% of the sodium is reabsorb-able.
• Passive water reabsorption and sodium reabsorption are closely related, so as sodium travels, water also does.
• Water flow maintains extracellular body fluid volume by balancing the osmotic pressure within or across tubule walls.
• Hence, the statements (a) and (b) are correct.
• The reabsorption of food and nutrients back into the blood stream also takes place. So, statement (d) is true.

(iv) a, b, d- correct option

• The water and sodium gets reabsorbed into the blood stream.
• The food nutrients also gets reabsorbed.
• Hence, this option is correct.

(i) a, d- incorrect option

• Statements a and d are correct.
• But this option misses out on statement b.
• Hence, this option is incorrect.

(ii) b, d- incorrect option

• This option does not include the reabsorption of sodium.
• Hence, this option is incorrect.

(iii) a, c, d- incorrect option

• Reabsorption in kidney majorly involves the reabsorption of water.
• This option does not include that.
• Hence, this option is incorrect.
