Which system is primarily involved with delivering hormones throughout the body?

• A. Respiratory
• B. Endocrine
• C. Excretory
• D. Immune

Answer: (B)

The endocrine system is primarily responsible for delivering hormones throughout the body. It comprises various glands, such as the pituitary, thyroid, adrenal glands, and pancreas, which secrete hormones directly into the bloodstream. These hormones serve as chemical messengers that communicate between different parts of the body, regulating processes such as metabolism, growth, mood, and reproductive functions. The widespread distribution of hormones via the circulatory system allows for coordinated control over diverse physiological processes, ensuring the body can respond appropriately to internal and external changes. The other systems listed do not primarily focus on hormone delivery. The respiratory system is mainly concerned with gas exchange and maintaining oxygen and carbon dioxide levels in the blood. The excretory system is involved in removing waste products and regulating water and electrolyte balance in the body. The immune system is responsible for defending against pathogens and diseases, primarily through the action of immune cells and antibodies. Each of these systems plays crucial roles in maintaining homeostasis, but the endocrine system is uniquely specialized for hormone distribution and regulation.
