Question

histological diagram of endocrine glands
​

Answer 1

Answer:

No cell is an island. With the emergence of multi-cellular organisms appeared a need for communication between cells to coordinate the activities of specialized tissues for the benefit of an entire organism. The endocrine system plays a major role in this process.

Now, we know that practically every organ sends signals (hormones) to other body parts to elicit biological responses that adjust the behavior of these target organs to maintain homeostasis. The heart does it, fat does it, as do the stomach and intestines. However, this chapter covers only the glandular organs that secrete hormones as their primary function.

The “classic” endocrine glands in the human body include the pituitary, thyroid, parathyroid, adrenal

and pineal glands. Some other glands with endocrine cells have both endocrine and non-endocrine functions. The pancreas is one of these glands, where the non-endocrine function is secreting digestive enzymes to the small intestine.
