-liver: production of bile (which goes in the gallbladder)

accessory organs -gallbladder: bile is stored here; breakdown of fat

-pancreas: storage of digestive enzymes


-CARBOHYDRATES:

*enzymes: amylase, sucrase and maltase

*product: glucose

*fr. mouth to the end of the small intestine



-PROTEIN:

nutrient, enzymes, result and *enzymes: proteases

location *product: amino acids

*stomach to the small intestine

CARDIOVASCULAR AND
-circulation consists of 2 paths:
LYMPHATIC
1.cardiovascular

2.lymphatic


-consists of:
