Pancreas and Nutrition
Pancreas Functions: 1. Exocrine 2. Endocrine
Pancreas Exocrine: Secretes into ducts, dumps into duodenum. 3 big Ezymes?
1. Trypsin – works on proteins 2. Lipase – works on fats EXOCRINE 1. Trypsin – works on proteins 2. Lipase – works on fats 3. Amylase – works on Carbohydrates (starch)
Secretes hormones into blood stream. ENDOCRINE ENDOCRINE: Secretes hormones into blood stream.
1. Insulin: Decrease glucose in blood: ENDOCRINE 1. Insulin: Decrease glucose in blood: A) Allows cells to take in glucose B) glucose glycogen
1. Glucagon: INCREASE glucose in blood: ENDOCRINE 1. Glucagon: INCREASE glucose in blood: A) Glycogen glucose B) Cell release glucose into blood stream

Carbohydrates Contain C, H, O Quickest form of energy Simple: only has sugar Complex: Sugars + fiber + other stuff.
Carbohydrates Energy: 4.1 Kcals gram
LIPIDS Highest energy source 9.3 Kcals gram
4.1 Kcals gram Good energy, but harder to use then carbohydrates Proteins Good energy, but harder to use then carbohydrates 4.1 Kcals gram
But you need them for coenzymes Vitamins and Minerals NO ENERGY But you need them for coenzymes
OTHERS Water: Used to dissolve things
Fiber Prevents Colon cancer, keeps things moving along through the L.I.
