Answer:
The correct answer is D.
Step-by-step explanation:
- A is wrong because the endocrine glands are ductless.
- B is wrong because the product is not lipid soluble therefore it can not diffuse through cell membranes.
- C is wrong because only steroid hormones (such as androgens and estrogens) and thyroid hormone are lipid soluble.
- The correct answer is D because all endocrine glands secrete their products into the bloodstream.
