GENERAL HISTOLOGY

Detailed explanation-1: -Exocrine glands can be found in many different organs and have many different functions. Exocrine glands secrete sweat from your sweat glands, tears from your lacrimal glands, saliva from your salivary glands, milk from your mammary glands and more.

Detailed explanation-2: -Merocrine (or eccrine) is a term used to classify exocrine glands and their secretions in the study of histology. A cell is classified as merocrine if the secretions of that cell are excreted via exocytosis from secretory cells into an epithelial-walled duct or ducts and then onto a bodily surface or into the lumen.

Detailed explanation-3: -Sebaceous glands are holocrine glands, and sweat glands (both eccrine and apocrine ones) are merocrine glands.

Detailed explanation-4: -They can be further classified as merocrine (eccrine) glands. They secrete a watery fluid which is hypotonic to plasma its evaporation is important for thermoregulation. Sweat contains water, sodium, potassium, chloride, urea ammonia and lactic acid.

Detailed explanation-5: -There are three types of sweat glands in the human body: holocrine, apocrine, and merocrine.
