Question

Question 2 (18 points) Associate the processes of digestion with: the name given to the food at that point, the parts of the digestive tract involved and its functions. BUCCAL CAVITY (LIPS, TEETH, CHEEKS, TONGUE, SALIVARY GLANDS) 1. NAME OF FOOD AFTER INGESTION & MIXING WITH ENZYMES FECES PARTS OF TRACT WHERE INGESTION OCCURS 2. LARGE INTESTINE EXPULSION OF NON DIGESTIBLE SUBSTANCES OF DIGESTIVE TRACT OUT OF THE BODY 3. FUNCTION OF THE INGESTION 4. NAME OF FOOD DURING PROPULSION TRANSFORMATION (VIA ENZYMES) OF MACROMOLECULES TO MONOMERS FOR THE CELL'S USE PARTS OF TRACT WHERE PROPULSION OCCURS 5. 6. FUNCTIONS OF PROPULSION BOLUS 7. NAME OF 'FOOD DURING MECHANICAL DIGESTION (2) BUCCAL CAVITY TO LARGE

Explanation / Answer

1. name of food after ingestion and mixing with enzymes - bolus

2.parts of tract where ingestion occurs - buccal cavity(lips,teeth,cheeks,tongue,salivary gland)

3.functions of ingestion - introduction of the nutrition source into the digestive tract.

4.name of food during propulsion - food,bolus,chyme,feces.

5.parts of tract where propulsion occurs - buccal cavity to large intestine

6.functions of propulsion - deglutition and peristalsis

7.name of food during mechanical digestion - bolus,chyme,feces

8.parts of tract where mechanical digestion occurs - buccal cavity to large intestine

9.functions of mechanical digestion - mastication,churning,segmentation,haustral churning.

10.name of food during chemical digestion - bolus,chyme,feces

11.parts of tract where chemical(human+bacterial) digestion occurs - stomach to large intestine

12.functions of chemical digestion - transformation (via enzymes) of macromolecules to monomers for the cell's    use.

13.name of food during absorption - chymes,feces

14.parts of tract where absorption occurs - oropharynx to large intestine

15.functions of absorption - passage of monomers from digestive tract to cardiovascular/lymphactic systems for distribution to cells

16.name of food during defecation - feces

17.parts of tract where defecation occurs - large intestine

18.functions of defecation - expulsion of non digestive substances of digestive tract out of the body
