Path of digestion

1. mouth• chew food using teeth (adults = 32)• salivary glands-moisten & digest
food• tongue- moves food & has taste buds

Tongue pushes food down the digestive system

epiglottis•flap that covers windpipe when you swallow

2. esophagus•tube that carries food stomach
•moves food down by squeezing rings of muscles

3. stomach•walls covered w/ protective lining of mucus

4. small intestine•pancreas & liver
send chemicals here
•covered w/ villi-–tiny finger shaped structures
–give more surface area to absorb food

5. large intestine (colon)
•has helpful bacteria- make vitamins & keep out disease causing bacteria
•takes water & salts from wastes YouTube video-Where Did I Go-Path of Digestion

1. kidneys•pair of organs
that remove water, salt & wastes from blood
•regulate & control level of salts & water in blood

•take in oxygen & remove carbon dioxide
