Question

Which of the following sequences is correct regarding regulation of kidney function?

• A. An excess loss of water from body $\to$ Hypothalamus $\to$ Ormoreceptors $\to$ Neurohypophysis $\to$ ADH $\to$ Increases water permeability of DCT and CT $\to$ Prevention of diuresis
• B. An excess loss of fluid from body $\to$ Ormoreceptors $\to$ Hypothalamus $\to$ Neurohypophysis $\to$ ADH $\to$ Increases wter permeability of DCT and CT $\to$ PRevention of diuresis
• C. An excess loss of fluid from body $\to$ Ormoreceptors $\to$ Hypothalamus $\to$ Neurohypophysis $\to$ Aldosterone $\to$ Water permeability of DCT and CT increases $\to$ Prevention of diuresis
• D. An excess loss of fluid from body $\to$ Ormoreceptor $\to$ Hypothalamus $\to$ Adenohypophysis $\to$ ADH $\to$ Increases water permeability of DCT and CT $\to$ Prevention of diuresis

Answer 1

The correct option is B An excess loss of fluid from body $\to$ Ormoreceptors $\to$ Hypothalamus $\to$ Neurohypophysis $\to$ ADH $\to$ Increases wter permeability of DCT and CT $\to$ PRevention of diuresis

Changes in blood volume, body fluid volume and ionic concentration activate the osmoreceptors in the body. These receptors further stimulate the hypothalamus to release ADH from the neurohypophysis. ADH increases water reabsorption from DCT and CT, thereby preventing diuresis.
