Directions: In the following questions, a statement of assertion (A) ...
Assertion (A): In humans, a major amount of water is absorbed by the tubular part of nephron.
Reason (R): Absorption of water depends on the dissolved waste to be excreted from the body.
Explanation:
The assertion states that in humans, a major amount of water is absorbed by the tubular part of the nephron. This is a true statement. The nephron is the functional unit of the kidney and is responsible for the filtration and reabsorption of substances from the blood. The tubular part of the nephron, which includes the proximal convoluted tubule, the loop of Henle, and the distal convoluted tubule, plays a crucial role in the reabsorption of water.
The reason states that the absorption of water depends on the dissolved waste to be excreted from the body. This statement is not correct and is not the correct explanation of the assertion. The absorption of water in the nephron is primarily regulated by the hormone antidiuretic hormone (ADH), also known as vasopressin. ADH is released by the pituitary gland in response to changes in blood osmolarity and acts on the collecting ducts of the nephron to increase the permeability of water. This allows water to be reabsorbed from the urine back into the bloodstream, reducing water loss.
The absorption of water in the nephron is not directly dependent on the dissolved waste to be excreted from the body. While the reabsorption of water in the nephron does occur alongside the reabsorption of various solutes and waste products, the primary regulation of water absorption is through hormonal control.
Therefore, both the assertion and reason are true, but the reason is not the correct explanation of the assertion. The correct answer is option B.
Reason (R): Absorption of water depends on the dissolved waste to be excreted from the body.
