Explanation Exocrine glands harbor different mechanism to discharge different types of secretions. There are three different mechanisms by which exocrine glands can discharge their secretion: • Merocrine glands: Merocrine glands pack their secretion in structures known as secretory vesicles and discharge their secretion by exocytosis. The cells remain intact and are not harmed in any way by producing the secretion. • Apocrine glands: The cells of apocrine glands accumulate their secretory products within the apical area of their cytoplasm...

Chapter 4, Problem 4CR

Summary Introduction

To explain:

The three secretion methods of exocrine glands along with their working.

Introduction:

Exocrine glands are divided by the nature of their secretions as serous glands, mucous glands, or mixed glands. Serous glands synthesize and discharge a nonviscous, watery fluid like sweat, tear milk. Mucous glands discharge mucin that forms mucus mixed with water. Mixed glands contain both serous and mucous cells and produce a mixture of the two types of secretions.
