Pancreas and
Nutrition
Pancreas
•Functions:
•1. Exocrine
•2. Endocrine
Pancreas
•Exocrine: Secretes
into ducts, dumps
into duodenum.
•3 big Ezymes?
EXOCRINE
• 1. Trypsin – works on
proteins
• 2. Lipase – works on fats
• 3. Amylase – works on
Carbohydrates (starch)
ENDOCRINE
•ENDOCRINE:
•Secretes hormones
into blood stream.
ENDOCRINE
• 1. Insulin: Decrease
glucose in blood:
• A) Allows cells to take in
glucose
• B) glucose  glycogen
ENDOCRINE
• 1. Glucagon:
INCREASE glucose in
blood:
• A) Glycogen  glucose
• B) Cell release glucose
into blood stream
DISORDERS
•Diabetes: High
blood sugar
•There are two types
DIABETES
•Type I: Lack
functioning insulin,
presents wrong
message, genetic
DIABETES
•Type II: Cells do not
respond to insulin,
partially genetic,
mostly environmental
NUTRITION
NUTRITION
•Nutrients: Things in
food that promote
health
NUTRITION
•calories: Amount of
energy needed to raise
1 gram of water 1°
(degree) Celsius - A
unit of energy.
NUTRITION
•1 Kilocalorie =
1000 calories
•1Kcal = 1 Calorie
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
Proteins
• Good energy, but harder to
use then carbohydrates
4.1 Kcals
gram
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.
