Mark the following statements as true or false. If a statement is false, correct it to make a true statement.
d. ADH triggers water reabsorption from the nephron loop.

검증된 단계별 안내

Understand the role of ADH (antidiuretic hormone): ADH is a hormone that helps regulate water balance in the body by increasing water reabsorption in the kidneys. It acts specifically on the collecting ducts and distal tubules of the nephron, not the nephron loop.

Analyze the statement: The statement claims that ADH triggers water reabsorption from the nephron loop. This is incorrect because the nephron loop (loop of Henle) is primarily involved in concentrating urine through countercurrent mechanisms, and ADH does not act directly on this part of the nephron.

Correct the false statement: The correct version of the statement should be: 'ADH triggers water reabsorption from the collecting ducts and distal tubules of the nephron.'

Review the anatomy of the nephron: The nephron consists of several parts, including the glomerulus, proximal tubule, nephron loop (loop of Henle), distal tubule, and collecting duct. Each part has a specific function, and ADH primarily affects the distal tubule and collecting duct.

Conclude the correction: The original statement is false, and the corrected version clarifies the specific action of ADH in the nephron.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Antidiuretic Hormone (ADH)

Antidiuretic Hormone (ADH), also known as vasopressin, is a hormone produced by the hypothalamus and released by the posterior pituitary gland. It plays a crucial role in regulating water balance in the body by promoting water reabsorption in the kidneys, specifically in the collecting ducts, rather than the nephron loop.

Nephron Structure and Function

The nephron is the functional unit of the kidney, consisting of various segments including the glomerulus, proximal tubule, loop of Henle, distal tubule, and collecting duct. Each segment has specific roles in filtering blood, reabsorbing essential substances, and excreting waste, with ADH primarily affecting the collecting duct rather than the nephron loop.

Water Reabsorption Mechanism

Water reabsorption in the kidneys occurs through osmosis, where water moves from the renal tubules back into the bloodstream. This process is influenced by hormones like ADH, which increases the permeability of the collecting ducts to water, allowing for greater reabsorption and concentration of urine, rather than occurring in the nephron loop.

Mark the following statements as true or false. If a statement is false, correct it to make a true statement.d. ADH triggers water reabsorption from the nephron loop.
