Which of the following produces both hormones and enzymes
lleum
pancreas
gall bladder
kidney
Explanation
The pancreas is a mixed gland, meaning it produces both hormones (like insulin and glucagon) and enzymes (like amylase, lipase, and trypsin).
-
Exocrine Function (Enzymes):
The pancreas's exocrine tissue produces digestive enzymes that are released into the pancreatic duct, which then transports them to the small intestine to aid in digestion. These enzymes include:- Amylase: Breaks down carbohydrates.
- Lipase: Breaks down fats.
- Protease (trypsin and chymotrypsin): Breaks down proteins.
-
Endocrine Function (Hormones):
The pancreas's endocrine tissue, specifically the islets of Langerhans, produces hormones that are released directly into the bloodstream. The main hormones produced are:- Insulin: Lowers blood sugar levels.
- Glucagon: Raises blood sugar levels.
