• Function: Break down food into molecules that can used by cells

• Enzymes, acids, hormones, bile aid in breakdown

• Sphincters (ring of muscle) separate sections

• Nutrients passed into the circulatory system to be distributed in the blood

Oral cavity

Page 5: Stomach Small Intestine Large Intestine Pharynx Esophagus Liver Gall Bladder Pancreas Oral cavity

• Mechanical digestion: Teeth grind food

• Chemical digestions: Saliva (amylase) begins to breakdown starches

• Bolus is created (ball of chewed & moistened food)

Pharynx

Page 8: Stomach Small Intestine Large Intestine Pharynx Esophagus Liver Gall Bladder Pancreas Oral cavity

• Epiglottis seals off the trachea

• Bolus pushed down the esophagus by the tongue

Esophagus

Page 10: Stomach Small Intestine Large Intestine Pharynx Esophagus Liver Gall Bladder Pancreas Oral cavity

• Connects mouth with stomach

• Peristalsis: Muscular movement pushes food along– Bolus pushed down

the esophagus by muscles

Stomach

Page 12: Stomach Small Intestine Large Intestine Pharynx Esophagus Liver Gall Bladder Pancreas Oral cavity

• Function: Prepares food for absorption

• Chemical digestion– Pepsin (enzyme)

digests proteins– Stomach acids mix

• Mechanical digestion– Muscles contract to

churn the bolus (~4 hours)

• Chyme created: paste-like mixture of food, enzymes, acids

• Peristalsis pushes chyme through sphincterClick pic to play

Small Intestine

Page 14: Stomach Small Intestine Large Intestine Pharynx Esophagus Liver Gall Bladder Pancreas Oral cavity

• Function: Absorption of nutrients

• Duodenum– Chemical digestion:

Enzymes from the liver, gallbladder, pancreas released to aid digestion

– Mechanical digestion: Muscular contractions mix & churn the chyme

• Peristalsis pushes the chyme along

• Nutrients absorbed into the capillaries of the s. intestine

Liver

Gall Bladder

Page 17: Stomach Small Intestine Large Intestine Pharynx Esophagus Liver Gall Bladder Pancreas Oral cavity

• Functions:

– 1) Break down toxic chemicals (alcohol)

– 2) Produces bile to break down fats

• Gall Bladder: Stores bile until chyme moves into duodenum

Pancreas

Page 20: Stomach Small Intestine Large Intestine Pharynx Esophagus Liver Gall Bladder Pancreas Oral cavity

• Functions: – 1) Release enzyme into duodenum to break down starches &

lipids– 2) Releases insulin into the blood (diabetes)

Large Intestine

Page 22: Stomach Small Intestine Large Intestine Pharynx Esophagus Liver Gall Bladder Pancreas Oral cavity

• AKA: Colon• Peristalsis continues to

push the chyme• Remaining water is

absorbed from the chyme– Undigested material

solidifies (feces)

• Nutrients from bacteria absorbed

• Feces exits the body through the rectum & anus

• Most nutrients are absorbed at which organ?

• E (small intestine)

• Which organ produces bile to help digest fats?

• K (liver)

• Which organ absorbs water from chyme to solidify waste?

• F (large intestine)

L

• Which organ is the location where the gall bladder and pancreas release fluids to mix with the chyme?

• I (Duodenum)
