Zeis glands secrete what?

Explanation:
Zeis glands are sebaceous glands located along the eyelid near the eyelashes. They produce sebum, a lipid-rich oily secretion that coats the eyelashes and eyelid margin to keep them lubricated and to reduce friction during blinking. This holocrine secretion involves mature sebocytes disintegrating to release lipids into the duct. In contrast, sweat is a watery secretion from sweat glands, serous fluid is a clear, watery fluid from serous glands, and mucin is a glycoprotein component of mucus—none of which describe Zeis gland output.
