What is the difference between exocrine and endocrine glands in terms of how they release their secretions?
What is the difference between exocrine and endocrine glands in terms of how they release their secretions?
Exocrine glands secrete their products into ducts that empty at the surface of the covering and lining of the epithelium or directly onto a free surface, while endocrine glands are ductless; their secretory products (hormones) enter the extracellular fluid and diffuse into the blood.
What are the three types of exocrine glands and how do they release their secretions?
What are the three types of exocrine glands and how do they release their secretions?
The three types of exocrine glands are merocrine, apocrine, and holocrine. Merocrine glands release their secretions via exocytosis, apocrine glands pinch off their apical surfaces along with their secretory vesicles, and holocrine gland cells lyse and are destroyed after accumulating their products within their cytoplasm.
