What is the role of the adrenal glands in the body?

• A. To produce insulin
• B. To regulate metabolism
• C. To produce hormones such as adrenaline
• D. To filter blood

Answer: (C)

The adrenal glands play a crucial role in the endocrine system by producing various hormones that are essential for many bodily functions. One of the key hormones produced by the adrenal glands is adrenaline (also known as epinephrine), which is involved in the body’s fight-or-flight response. When an individual experiences stress or danger, adrenaline is released into the bloodstream, leading to increased heart rate, heightened alertness, and other physiological changes that prepare the body to respond effectively to the situation.

Additionally, the adrenal glands produce other important hormones, such as cortisol, which helps regulate metabolism, immune response, and stress responses. However, the specific role highlighted in this context is the production of hormones like adrenaline, which is vital for immediate reactions to stress and ensuring that the body is ready to respond to various challenges.

The other options describe functions associated with different organs or systems in the body. For example, insulin production is primarily the role of the pancreas, while metabolism regulation can involve multiple organs, including the thyroid gland. Filtering blood is performed by the kidneys. Therefore, the statement that the adrenal glands produce hormones such as adrenaline accurately captures their significant role in the body.
