21. Digestive System Functions (The Alimentary Canal)

22. Joke of the Day:

23. Alimentary Canal:
The passage (including the esophagus, stomach, and intestines) that food passes through the body from mouth to anus

24. Types of Digestion
Mechanical (M): Chewing, churning of food in stomache
Chemical (C): Enzymes – From the Mouth to the Small Intestine

25. Mouth (M,C) First Site of Digestion!
(M) chewing
(C) Salivary Amylase breaks down starch

26. Pharynx(M)
Initiates swallowing

27. Esophagus (M)
Transports food from mouth to stomach through “Peristalsis”
Peristaltic Waves: Waves of muscular contractions that propel contents from one point to another

28. Stomach(M,C) (process food then transport)
(M) churning to create a “Bolus”
Bolus: Creamy paste that forms as the food in th stomach is repeatedly mixed with gastric juices
(C) HCl, pepsin kill bacteria and break down proteins

29. Duodenum(C)
1ST 10 inches of small intestine. Bile secreted here.

30. Jejunum(M,C) Next 8 feet of small intestine.
Food absorption, enzyme action.

31. Ileum (M,C) “Terminal” portion of the small intestine
Absorption of food, enzyme action

32. Ascending colon(M) Part 1 of the Large Intestine.
Water, Nutrient and Electrolyte absorption

33. Transverse colon(M) Part 2 of the Large Intestine
Water, Nutrient and Electrolyte absorption

34. Descending colon(M) Part 3 of the Large Intestine
Water, Nutrient and Electrolyte absorption

35. Sigmoid colon(M)
Water and Electrolyte absorption

36. Rectum(M)
Storage of feces

37. Anal canal(M)
Sphincter for “waste management”

38. Warning – Prolapsed rectum ahead!
