What process is primarily responsible for the transport of hormones within the endocrine system?

• A. Diffusion
• B. Circulation
• C. Absorption
• D. Secretion

Answer: (B)

The transport of hormones within the endocrine system is primarily facilitated by circulation. Hormones are secreted directly into the bloodstream by endocrine glands, allowing them to travel throughout the body to reach target organs or tissues. This circulatory transport is essential because hormones often act at distant sites, and the bloodstream provides an efficient means of delivery. Circulation allows for the rapid distribution and effective regulation of various physiological processes influenced by hormones, such as metabolism, growth, and homeostasis. The other processes mentioned—diffusion, absorption, and secretion—play roles in different biological contexts but do not encompass the systemic transportation function that circulation provides in the context of hormonal transport.
