Question

decreased blood volume or blood pressure, or high extracellular k+ concentration (hyperkalemia), can cause _______________ to be released from the organ the arrow is pointing at. growth hormone cortisol aldosterone

Explanation:

The arrow points to the adrenal gland. Decreased blood volume or pressure and high extracellular K+ levels stimulate the release of aldosterone from the adrenal gland, which helps regulate blood volume, blood pressure, and K+ levels. Growth hormone is released by the pituitary gland and is not related to these stimuli. Cortisol is also released by the adrenal gland but in response to stress - not specifically to the conditions mentioned here. Aldosterone is the correct hormone for these specific triggers.

Answer:

aldosterone
