Aldosterone is a hormone made by the adrenal glands, which sit on top of the kidneys. Its main job is to control the levels of sodium (Na⁺) and potassium (K⁺) in the blood.
Aldosterone works by telling the kidneys to:
Keep sodium in the blood
Remove potassium through urine
This balance helps the body maintain normal blood pressure, fluid levels, and electrolyte balance.
Other options do not control sodium and potassium:
Cortisol is a stress hormone that helps with metabolism and immune response.
Glycogens are stored forms of glucose, not hormones.
Pheromones are chemical signals for communication, not for regulating blood minerals.
Maintaining sodium and potassium levels is very important because it affects:
Heart function
Muscle contractions
Nerve signals
In short, Aldosterone is the hormone responsible for keeping sodium and potassium balanced in the blood. It is a key concept in Biology, especially in human physiology and the endocrine system.
