but salivary gland secrets enzymes...

Answer

Endocrine glands are the glands which do not have a duct and secrete the contents directly in the blood stream. Pancreas, adrenal gland and thyroid gland are the examples of the endocrine glands. Salivary gland is an exocrine gland. The gland contains many lobules which pour the saliva in the common salivary duct. The salivary duct empties the contents in the mouth.
Thus, the correct answer is option D.

Answer

Salivary Gland is not an endocrine gland

Salivary glands are not considered endocrine glands because they do not release their secretions (saliva) directly into the bloodstream. Instead, they release saliva into the oral cavity through ducts. Endocrine glands, on the other hand, release hormones directly into the bloodstream.

Endocrine Glands
- Endocrine glands are ductless glands that secrete hormones directly into the bloodstream.
- These hormones regulate various physiological processes in the body, such as growth, metabolism, and reproduction.

Pancreas
- The pancreas is an endocrine gland as it produces hormones such as insulin and glucagon, which regulate blood sugar levels.

Adrenal Gland
- The adrenal gland is an endocrine gland that produces hormones such as adrenaline and cortisol, which help the body respond to stress and regulate metabolism.

Thyroid Gland
- The thyroid gland is an endocrine gland that produces hormones such as thyroxine, which regulate metabolism and growth in the body.

In conclusion, while the pancreas, adrenal gland, and thyroid gland are all endocrine glands that release hormones directly into the bloodstream, the salivary gland is not an endocrine gland as it releases its secretions through ducts.
