Hormones
a. Are produced by exocrine glands
b. Are carried to all parts of the body in blood
c. Remain at constant concentration in the blood
d. Affect only non-hormone-producing organs

검증된 단계별 안내

Step 1: Understand the definition of hormones. Hormones are chemical messengers produced by endocrine glands, not exocrine glands. Endocrine glands release hormones directly into the bloodstream.
Step 2: Analyze option (a): Hormones are produced by exocrine glands. Since exocrine glands secrete substances through ducts to specific locations (like sweat or salivary glands), this statement is incorrect for hormones.
Step 3: Analyze option (b): Hormones are carried to all parts of the body in blood. Hormones travel through the bloodstream to reach target cells or organs, so this statement is correct.
Step 4: Analyze option (c): Hormones remain at constant concentration in the blood. Hormone levels fluctuate depending on physiological needs and feedback mechanisms, so this statement is incorrect.
Step 5: Analyze option (d): Hormones affect only non-hormone-producing organs. Hormones can affect various target organs, including those that produce hormones, so this statement is incorrect.

Hormone Transport in the Bloodstream

Hormones travel through the bloodstream to reach target cells throughout the body. This systemic transport allows hormones to affect distant organs, highlighting their role as chemical messengers in regulating physiological processes.

Hormone Specificity and Target Organs

Hormones affect specific target cells or organs that have appropriate receptors, which can include both hormone-producing and non-hormone-producing tissues. This specificity ensures precise regulation of bodily functions.
