WHAT IS THIS? AND…WHAT DOES IT DO???
THE DIGESTIVE SYSTEM
CHAPTER 24, PAGE
WHAT DOES IT CONSIST OF?
THE DIGESTIVE TRACT INCLUDES THE MOUTH, PHARYNX,
ESOPHAGUS, STOMACH, SMALL INTESTINE, AND LARGE INTESTINE.
THE LIVER, GALLBLADDER, PANCREAS, AND SALIVARY GLANDS ADD
MATERIALS TO THE DIGESTIVE TRACT TO HELP BREAK DOWN FOOD.
VOCABULARY 
1. MECHANICAL DIGESTION- THE PROCESS OF BREAKING DOWN FOOD
BY MASHING OR CRUSHING
2. CHEMICAL DIGESTION-USING ENZYMES TO BREAK FOOD DOWN
3. PANCREAS-ORGAN BETWEEN STOMACH AND SMALL INTESTINE THAT
MAKES FLUID FOR SMALL INTESTINE (SODIUM BICARBONATE, ENZYMES,
HORMONES)
4. LIVER-REDISH/BROWN ORGAN FOUND ON RIGHT SIDE UNDER RIBS
(MAKES BILE, STORES NUTRIENTS, BREAKS DOWN TOXINS)
5. GALLBLADDER—SACLIKE ORGAN STORING BILE (TO HELP
BREAKDOWN FAT)
PROCESS OF DIGESTION
1. MECHANICAL DIGESTION IN MOUTH (SALIVA)
2. TONGUE PUSHES FOOD TO PHARYNX
3. MUSCLE CONTRACTIONS (PERISTALSIS) SQUEEZES FOOD IN ESOPHAGUS
TO STOMACH
4. IN STOMACH, ENZYMES ARE USED TO KILL BACTERIA AND BREAK FOOD
DOWN INTO NUTRIENTS (BOTH MECHANICAL AND CHEMICAL DIGESTION)
MAKING CHYME
5. CHYME ENTERS THE SMALL INTESTINE (WHERE NUTRIENTS ARE ABSORBED)
6. PANCREAS, LIVER, GALLBLADDER ADD ENZYMES TO FINISH DIGESTION
7. LARGE INTESTINE ABSORBS WATER AND GETS RID OF WASTE
QUESTIONS IN-CLASS
1. HOW DOES THE DIGESTIVE SYSTEM WORK WITH THE CIRCULATORY
(CARDIOVASCULAR) SYSTEM?
2. WHAT ORGANS IN THE DIGESTIVE SYSTEM ARE NOT PART OF THE
DIGESTIVE TRACT?
3. WHAT IS THE FUNCTION OF SALIVA?
4. NAME THREE PLACES IN THE DIGESTIVE TRACT WHERE CHEMICAL
DIGESTION TAKES PLACE.
5. HOW DOES THE STRUCTURE OF THE SMALL INTESTINE HELP IT ABSORB

1. USE ONE NOTECARD TO WRITE A VOCABULARY WORD ON THE
FRONT AND ONE ON THE BACK
