What is the most abundant corticosteroid hormone secreted by the adrenal cortex?

Cortisol is recognized as the most abundant corticosteroid hormone produced by the adrenal cortex. It plays a vital role in regulating a variety of physiological processes, including metabolism, immune response, and stress management. Secreted in response to adrenocorticotropic hormone (ACTH), cortisol aids in the metabolism of carbohydrates, fats, and proteins while also acting to maintain blood glucose levels and influence blood pressure.

In comparing cortisol to other hormones secreted by the adrenal cortex, dehydroepiandrosterone (DHEA) is primarily an androgen precursor, contributing to the development of male and female sex hormones but is less abundant in circulation than cortisol. Aldosterone, while a key hormone involved in regulating sodium and potassium levels and fluid balance, is produced in smaller quantities than cortisol. Corticosterone, also a corticosteroid, is involved in stress response and helps regulate energy, but it is not secreted in amounts comparable to cortisol. Thus, in terms of predominance and overall impact on bodily functions, cortisol stands out as the leading corticosteroid hormone.
