Which of the following human endocrine glands is located just above the kidneys and secretes hormones such as cortisol and adrenaline to manage physiological stress?

💡 Solution & Explanation

The adrenal glands sit atop the kidneys and are divided into the outer cortex, which produces mineralocorticoids and glucocorticoids like cortisol, and the inner medulla, which secretes catecholamines like adrenaline and noradrenaline for fight or flight responses. The thyroid gland regulates metabolic rate, while the pituitary gland controls several other endocrine glands. Adrenaline increases heart rate and blood pressure instantly during stress.
