Word origin

The term 'exocrine' is derived from the Greek words 'exo-' meaning 'out,' and 'krinein,' which means 'to separate' or 'to sift.' The concept of exocrine glands was developed as scientists sought to understand the differences between glandular functions in the body. The classification of glands into exocrine and endocrine types became important in medical and biological sciences, particularly in the context of understanding how various substances are secreted in the body. Over time, the term has been widely adopted in anatomy and physiology to describe the various glandular systems that are distinct in their methods of secretion.
