Regulation of blood glucose

Exocrine gland - An exocrine gland is a gland which secretes molecules into a duct which carries the molecules to where they're used. An example of an exocrine gland is the pancreas (is also endocrine).

Endocrine gland - An endocrine gland is a gland which secretes hormones directly into the blood stream e.g. adrenaline, insulin etc.

Pancreatic duct - The pancreatic duct is a tube which collects all the secreted enzymes and fluid (containing NaHCO3) from the acinar cells and carries the fluid to the small intestine.

Islet of langerhans - The islet of langerhans are patches of tissue which are clusters around blood capillaries containing alpha + beta cells which secrete hormones directly into the blood.

Alpha cells - Secrete glucagon which causes blood glucose levels to rise

Beta Cells - Secrete the hormone insulin which causes blood glucose levels to decrease.
