Answer:
The given blank can be filled with aldosterone.
Step-by-step explanation:
Aldosterone refers to a steroid hormone produced by the adrenal glands. It functions as the chief regulator of the water and salt balance of the body and is thus classified as a mineralocorticoid.
It is the hormone generated in the outer part of the adrenal glands, that is, cortex positioned above the kidneys. It also makes water to get reabsorbed along with sodium, which enhances the volume of blood and also blood pressure.
