Adrenal Glands

Definition

Adrenal glands are small glands located on top of each kidney that produce hormones important for regulating metabolism, immune response, blood pressure, and stress response.

Scientific / Technical Definition

Adrenal glands, also known as suprarenal glands, are endocrine glands that consist of two distinct regions: the adrenal cortex and the adrenal medulla. The cortex produces steroid hormones such as cortisol, aldosterone, and androgens, while the medulla produces catecholamines including adrenaline and noradrenaline. These hormones play a critical role in maintaining homeostasis and responding to stress.

Benefits

• Regulate metabolism and energy production
• Manage stress response through hormone release
• Control blood pressure through aldosterone production
• Influence immune system response

Examples

• Corticosteroids like cortisol produced by the adrenal cortex
• Epinephrine (adrenaline) involved in fight-or-flight response

Additional Information

• Effects: Adrenal glands are crucial for the body's ability to respond to stress and maintain homeostasis by influencing cardiovascular function, metabolism, and immune system regulation.
