INTRO:

TODAY TALK ABOUT WHAT? STOMACH. DIGESTIVE SYSTEM ITSELF ONE OF 11 MAJOR ORGAN SYSTEM IN BODY. DIGESTIVE SYSTEM DIFFERENT. ITS OWN. REMEMBER WORK WITH 10 OTHER ORGAN SYSTEMS IN BODY. HAVE SPECIAL FUNCTIONS ON ITS OWN. THAT ALLOW YOU LIVE AND HAVE BALANCED SYSTEM, HOMEOSTASIS. THAT WE ALL ABOUT.

FROM BODY VIEW DIGESTIVE SYSTEM DIVIDED 2 GROUPS. DIGESTIVE TRACT SOMETIMES CALLED ALIMENTARY CANAL OR GASTROINTESTINALTRACT – 30 FOOTTUBE START MOUTH TO ANUS. DIFFERENT NAMES FOR ALIMENTARY CANAL WILL GIVE – FOR EXAMPLE – MOUTH, ESOPHAGUS, STOMACH, SMALL INTESTINE, LARGE INTESTINE. ALL THAT WILL GIVE THEIR JOBS. ORGANS RELATED DIGESTIVE SYSTEM IMPORTANT. TEND TO NOT FIND IN DIGESTIVE SYSTEM BUT OUTSIDE. ORGANS LIKE TEETH, SALIVARY GLANDS, LIVER, GALLBLADDER AND PANCREAS WILL EXPLAIN.

IF TALK ABOUT DIGESTIVE SYSTEM WHOLE CAN SEE THAT HAVE FOUR IMPORTANT JOBS.

1) DIGESTIVE SYSTEM JOB ALLOW US TAKE FOOD DRINK IN BODY THAT CALLED INGESTION.
2) 2ND STEP CALLED TRUE DIGESTION. ONCE FOOD DRINK IN BODY NEED BREAKDOWN SMALL PART. DIGESTION HAVE IMPORTANT AREAS. FOOD DRINK ENTER YOUR BODY THEN BREAK DOWN.
3) NEXT IMPORTANT STEP THAT ABSORB. IF NO ABSORB. FOOD DRINK WILL EASY GO THROUGH BODY MEAN NOTHING. ABSORB MOVE NUTRIENTS TO BODY. SUGARS, PROTEINS, FATS, VITAMINS, MINERALS FROM ALIMENTARY CANAL BLOODSTREAM SEVERAL LAYERS TISSUES CAN ABSORB. CAN BRING GIVE ORGAN SYSTEMS BODY.
4) WASTE REMOVAL FUNCTION. ALL YOU EAT NOT DIGESTED OR ABSORBED. LARGE INTESTINE WILL TAKE CARE OF REMOVAL FECES.

NOW PRETEND THERE CHICKEN SANDWICH OR CHEESEBURGER OR CURRIED LENTILS. NOW FOLLOW WHERE GO DIGESTIVE SYSTEM. SEE WHAT HAPPENS. IMPORTANT FOLLOW THREE MACROMOLECULES. WATCH WHERE SUGARS (CARBOHYDRATES) DO-DO. WATCH PROTEINS AND FATS (LIPIDS). FOOD ENTER MOUTH DIGESTION START THERE. USE TEETH BREAK DOWN FOOD SMALL. THAT IMPORTANT MIX FOOD WITH CHEMICALS. SMALL PART CHEMICAL INCREASE. IN MOUTH SALIVIA USED HOW? BREAK CARBOHYDRATES, SUGARS; SMALL PART THAT CALL DISACCHARIDES. DISACCHARIDES SMALL PART SUGAR NOT. BUT GOOD START. CHEW FOOD MIX WITH SALIVA MAKE SMALL BALL CALLED BOLUS. SWALLOW YOU MOVE BOLUS TO STOMACH THROUGH ESOPHAGUS. STOMACH GET FOOD BALLS OR BOLI. NOW STOMACH DO-DO? BREAKDOWN OR START DIGEST PROTEINS FOUND IN FOOD BALLS. BODY VIEW STOMACH LIKE 3-D MIXING BOWL. STOMACH HAVE LAYERS MUSCLES ALLOW CONTRACT OR SHRINK 3-D. WALLS STOMACH CAN PRODUCE GASTRIC JUICE. JUICE HELP BREAKDOWN PROTEINS. INSIDE JUICE FIND WATER, HYDROCHLORIC ACID OR STOMACH ACID. ALSO HAVE IMPORTANT ENZYME, SCISSOR LIKE, HELP BREAK PROTEINS SMALL THAT CALL PEPTIDES. PEPTIDES IMPORTANT WORK IN STOMACH. IF YOU EAT FOOD HAVE LOTS PROTEIN, PEPSIN WORK WORK FOOD STAY LONG IN STOMACH. IF YOU EAT FOOD HAVE WATER OR SUGAR OR FOOD NOT HAVE PROTEIN, WILL GO FAST THRU STOMACH. AFTER PROTEIN DIGESTION SATISFIED, GO SMALL INTESTINE THRU SMOOTH MUSCLE CALLED PYLORIC SPHINCTER.

DIGESTIVE SYSTEM HAVE IMPORTANT PARTS. IF DECIDE WHICH MOST IMPORTANT PART THAT WHAT SMALL INTESTINE. SMALL INTESTINE HAVE DUODENUM THAT ATTACH TO STOMACH AND OTHER 2 TUBE. SMALL INTESTINE GET BILE FROM LIVER AND GALLBLADDER. ALSO GET CHEMICAL CALLED PANCREATIC JUICE THROUGH SPECIAL DUCTS FROM PANCREAS. 2 FOLD IN SMALL INTESTINE. FOOD GO DOWN EASY NOW MUST FINISH. FATS NOW IN SMALL INTESTINE DIVIDED AGAIN NOW CALLED TRIGLYCERIDES. PEPTIDES IN STOMACH DIVIDED SMALL CALLED AMINO ACIDS AND LEAVE SUGARS THAT NOT YET DIVIDED IN MOUTH BECOME DISACCHARIDES OR MONOSACCHARIDES. THAT WOW IMPORTANT. FINAL DIGESTION HAPPEN IN SMALL INTESTINES.

BEFORE CHEESEBURGER EAT, NOW WOW DIFFERENT. BODY TIME ENERGY WORK WORK PROCESS CAREFULLY PROCESS… NOW MUST BRING LEAVE THINGS FROM SMALL INTESTINES TO BLOODSTREAM NOW CAN GIVE SUGAR, FATS, MINERALS, PROTEINS TO TISSUES IN BODY. SMALL INTESTINE HAVE 3 PARTS – DUODENUM, JEJUNUM AND ILEUM. INSIDE HAVE SMALL FINGER-LIKE STRUCTURES CALL VILLI. THAT VILLI WORK HOW? BRING THINGS FROM DIGESTIVE SYSTEM TO BLOODSTREAM HOW ABSORB. MOST NUTRIENTS, FATS, SUGARS, PROTEINS ABSORB IN DUODENUM AND JEJUNUM. ILEUM CONNECT FINAL PART DIGESTIVE SYSTEM CALLED LARGE INTESTINE SAME AS COLON. ILEUM INSIDE FIND VILLI NO BUT LOT OF WATER ABSORB.

EAT FOOD FINISH, CHEW, SEND STOMACH TO MIX, SEND SMALL INTESTINE FOR FINAL DIGESTION AND ABSORB. IN ILEUM LEFT CALL FECES. NOT DIGEST LEFTOVERS. THAT UNABSORBABLE FROM BODY. MUST GET OUT THEN CAN STAY HEALTHY.

BODY GOOD CALL HOMEOSTASIS. ILEUM IN SMALL INTESTINE CONNECT LARGE INTESTINE CALLED CECUM. HANG FROM CECUM HAVE SMALL PIECE OF LYMPHATIC TISSUE CALL VERMIFORM APPENDIX AS APPENDIX. WHY HAVE APPENDIX NO ONE KNOW. SOME HAVE REMOVED NO SICK.

LARGE INTESTINE HAVE CECUM, COLON, RECTUM AND ANUS. NOW FECES GO START CECUM TRACE PATH GO WHERE. KEEP MIND TALK ABOUT THAT NOT DIGEST NOT ABSORB. THERE-IN CECUM FECES, WILL GO ASCENDING COLON, UP RIGHT SIDE BODY GO LEFTACROSS TRANSVERSE COLON GO DOWN, DESCENDING COLON BECOME LIKE S-SHAPE THAT CALLED SIGMOID COLON. LAST BUT IMPORTANT, SIGMOID COLON BRING FECES TO RECTUM. RECTUM BRING FECES OUT THROUGH ANUS.

LOOK WALLS TISSUES IN SIGMOID COLON SEE DIFFERENT FROM OTHER ORGANS. HAVE LARGE HOLLOW CUPS POUCHES IMPORTANT ALLOW ABSORB WATER FROM UNDIGESTED, UNABSORBED MATERIAL. LARGE INTESTINE WORK HARD ALLOW YOU GET WATER FROM FOOD AND DRINK. LARGE INTESTINE YOU FIND BACTERIA, GOOD BACTERIA. THAT BACTERIA HELP IMPORTANT FUNCTIONS. FOR EXAMPLE, INTESTINAL BACTERIA WILL MAKE VITAMIN-K, CAN HELP BLOOD CLOTTING.

INTESTINAL BACTERIA CAN HELP BALANCE PROTEINS AND SUGARS. THAT CAN’T ABSORB IN SMALL INTESTINES. NOW MATERIALS GO THRU COLON, LAST GO RECTUM. WALLS IN RETCUM HAVE SPECIAL TISSUE SEND SIGNALS CAN TELL HAVE FECES INCREASE WALLS. WILL LET YOUR BRAIN READY GO BATHROOM. RECTUM NEXT ANUS – FECES GO OUT.

ANUS HAVE 2-RINGS MUSCLE CALLED INTERNAL ANAL SPHINCTER AND EXTERNAL ANAL SPHINCTER. EXTERNAL ANAL SPHINCTER HAVE MUSCLES YOU CAN CONTROL. YOU CAN CONTROL WASTE MOVEMENT FROM RECTUM, OUT ANUS, OUT
