Aim: Explain the anatomy of the vertebrate digestive system and human digestion.  

 Hw. Study for nutrition unit test 3/29 am section and 3/28 

1. Review: What is digestion?

2. Vocab and Label the main organs and pay attention to function.

3. Complete chart using what you remember from explanation. 

4. Correct chart.5. Complete chart of glands using text book.

1. Vocabulary 

Glands:  Organs that produce a secretion.

Villi:Hairlike projections in the small intestine where absorption of nutrients takes place

Peristalsis:Alternate waves of relaxing and contracting of the muscular wall of the digestive tube.

Sphincter:Valve like structure that prevents fluids from backing up.

1. moistens food to ease swallowing.2. Amylase (in saliva) for digestion of carbs. 

1. food is moved by peristalsis into stomach. 

1. Produces hydrochloric acid2. Produces pepsin to start digesting proteins3. Churning (movement) mixes foods

1. Forms 3 enzymes (amylase, trypsin lipase)2. produces sodium bicarbonate to neutralize      acid.

1. Liver produces bile to emulsify (break into     droplets) fats2. Bile is stored in the gallbladder (sent to small intestine.

1. Final digestion of nutrients is completed2.  peristaltic movements deliver chime to L. I.3. Digested food is absorbed by villi (villus) into     blood  stream.

1. Vestigial structure not known function

1. Absorbs large amounts of water.2. Eliminates undigested food as solid waste.

Main functions, chemical made

1. physical digestion (teeth)to increase surface contact. 2. Chemical digestion of carbs starts here.

Vertebrates: Have 1 way digestive system with long small intestine where absorption takes place (s. I. to blood.)Gastric makes reference to stomach (gastric juice)• In the intestine villi increases contact surface for absorption • A villus contains capillaries to absorb sugars, amino acids, nucleotides, vitamins, minerals and water. • They  also contain a  Lacteal, which is a lymph vessel that   absorbs fatty acids and glycerol.
