Endocrine and Exocrine Glands

Endocrine glands are glands that secrete their products, mainly hormones, directly into the blood. Tropic hormones are hormones that have other endocrine glands as their target.

Addison's disease is caused by adrenal cortex insufficiency, leading to decreased production of cortisol and aldosterone hormones. The adrenal medulla secretes adrenaline and noradrenaline, while pituitary and thyroid are distinct endocrine glands.

Wharton's duct is the main excretory duct of the submandibular salivary gland, located on the floor of the mouth beneath the tongue. It drains saliva from the submandibular gland into the oral cavity.

Dysfunction of Meibomian glands causes dry eyes.

Thymus provides an environment for development of T-cells from hematopoietic progenitor cells. 

Rathke's pouch gives rise to the anterior pituitary (adenohypophysis) part of the pituitary gland.

Nest-like bodies called Hassall's corpuscles are found in thymus gland. 

Fenestrated capillaries allow small molecules and limited amounts of protein to diffuse and are present in the endocrine glands. 

Gastric glands are present in stomach. The gastric juice secreted kills harmful bacteria that enter with the food.

Parathyroid glands regulate calcium levels independently of pituitary control, responding directly to blood calcium concentrations. Thyroid, gonads, and adrenals all receive hormonal regulation from the pituitary gland through their respective tropic hormones.

Amylin is secreted by beta cells of pancreas.

Enkephalin is produced in kidney. It is a pentapeptide involved in regulating nociception in body.

Parotid salivary glands are present below and front of each ear and secrete their secretion via ducts in buccal cavity, i.e. they are exocrine glands. As they are outside buccal cavity, thus they are called external glands.

It is approximately 21-22.5 cm across its widest point, 15-17.5 cm at its greatest vertical height, and 10-12.5 cm from front to back. It is the largest gland present in the body.

Yes, it is correct as pancreas has both endocrine and exocrine parts. Lobules form the exocrine part and islets of Langerhans form the endocrine part.
