What is the primary function of the adrenal glands?

• A. To filter toxins from the blood
• B. To produce hormones that regulate stress response
• C. To store excess sugar and energy
• D. To produce lymphocytes for immunity

Answer: (B)

The primary function of the adrenal glands is to produce hormones that regulate the body's response to stress. Located on top of each kidney, these glands play a crucial role in the body's fight-or-flight response by releasing hormones such as cortisol, adrenaline (epinephrine), and norepinephrine. Cortisol helps maintain homeostasis during stress, increasing glucose availability for energy, while adrenaline and norepinephrine prepare the body for rapid action by increasing heart rate, blood pressure, and energy supply. This hormonal response is vital for survival, allowing the body to react effectively to stressful situations. The other options do not accurately represent the primary role of the adrenal glands. For instance, filtering toxins from the blood is primarily the function of the kidneys and liver. Storing excess sugar and energy relates to the pancreas and liver's roles in glucose metabolism. Lastly, the production of lymphocytes for immunity occurs primarily in the bone marrow and lymphatic system, not the adrenal glands. Therefore, the correct understanding highlights the adrenal glands' essential role in hormone production related to stress response.
