Question

The _____ system is composed of glands that synthesize and secrete products, called hormones, directly into the blood rather than through a duct. ______ are transported throughout the body where they influence only those cells that have receptors for that hormone.

a) Endocrine, Hormones
b) Exocrine, Enzymes
c) Lymphatic, Lymphocytes
d) Digestive, Nutrients

Answer 1

The correct answer is a) Endocrine, Hormones because the endocrine system is comprised of glands that release hormones directly into the bloodstream, which then interact with cells that have receptors for them.

Step-by-step explanation:

The endocrine system is composed of glands that synthesize and secrete products, called hormones, directly into the blood rather than through a duct. Hormones are then transported throughout the body, influencing only those cells that have receptors for that particular hormone. Therefore, the correct answer to the student's question is a) Endocrine, Hormones. Unlike the endocrine system, the exocrine system uses ducts to release enzymes, lymphatic system carries lymphocytes, and the digestive system processes nutrients.
