- AThyroid
- BPituitary
- CLacrimal
- DMore than one of the above
- ENone of the above
Show answer and explanation
Correct answer: (c) Lacrimal
Explanation
The lacrimal (tear) gland pours tears through ducts onto the eye, so it is an exocrine gland, not an endocrine gland.
Endocrine glands are ductless and release hormones straight into the blood: the pituitary, thyroid, parathyroid, adrenal, pineal and thymus, the islets of the pancreas and the gonads.
