First milk produced after birth is called colostrum, which is very nutritious. It provides passive immunity. Sebum is the substance secreted by sebaceous glands onto the surface of the skin. It is a fatty mildly antiseptic material that protects, lubricates and waterproofs the skin and hair; and helps to prevent desiccations. Cerumen is ear wax, which is secreted by ceruminous glands in the auditory meates of the outer ear. It protects delicate lining of the meat and thus helps to prevent micro-organisms from entering the ear. True milk is the fluid secreted by mammary glands of mammals.
