P66.**DIGESTION = FOOD PROCESSING**
Digestive system: three main functions
1. Breaks down food into usable molecules
2. molecules absorbed into bloodstream & carried
throughout body
3.eliminate waste from body
Mouth: Breaks down food physically (chewing) and
chemically (salivary gland enzymes)
Esophagus: muscular tube that connects mouth to
stomach
Epiglottis: flap that covers trachea
Stomach : J-shaped muscular pouch breaks down food
mechanically and chemically
Small intestine: chemical digestion occurs: ABSORBS
NUTRIENTS (6- 7 m long)
Large intestine: 1. Absorbs water 2. Compacts waste 3.
Eliminates waste (1.5 m long)

Circulatory system = BLOOD FLOW
p76
3 Jobs of circulatory system
1. Carries nutrients to cells
2. Removes waste from cells
3. Fights disease
Heart: hollow muscular organ that pumps blood throughout the body.
Four chambers (atriums on top, ventricles on the bottom..left & right of each)
*left side of heart : oxygen rich blood
*right side of heart low in oxygen
Arteries: blood vessels leaving the heart *aorta largest artery
Veins: blood vessels returning to the heart
Capillaries: narrow blood vessels where material (nutrients, waste & gases) is
exchanged between blood and body cells
Blood: complex tissue made of 4 parts: plasma, red blood cells, white blood cells
and platelets
