, DIGESTIVE SYSTEM -digestion: chemical and mechanical breakdown of food
-chemical: breakdown of food particles into small molecules
types of digestion
-mechanical: phy. breakdown of food (ex. mastication/chewing)
mouth: beginning of mechanical break down and beginning of
chemical digestion (amylase)
pharynx
esophagus
process of digestion stomach: peristalsis and hydrochloric acid & protease
small intestine: absorption and digestion
large intestine: absorption of water

-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
-LIPIDS:
*enzymes: lipases
*product: fatty acids and glycerol
*small intestine
-circulation: internal transport of fluid throughout the body;
exchange of gases, absorption of nutrients and disposal of
CIRCULATION SYSTEM:
wastes
CARDIOVASCULAR AND
-circulation consists of 2 paths:
LYMPHATIC
1.cardiovascular
2.lymphatic
-consists of:
CIRCULATION SYS:
1.heart: 4 chambers - atRia(RECEIVE) & ventricleS(PUMPS OUT)
CARDIOVASCULAR SYS
2.blood vessels
(PATHWAY)
3.blood
