Anatomy and Physiology Digestive System

1. Parts of the digestive process:

a. Ingestion bringing food in through the mouth.

b. Chewing/mastication chopping food into smaller pieces.

c. Muscular actions move the food through the alimentary canal in a wavelike fashion, and mix the food with digestive enzymes

d. Chemical digestion metabolic process of converting a large complex molecule into simpler molecules that are easily absorbed.

e. Secretion is the release of digestive enzyme that are needed for digestion.

f. Absorption movement of nutrients, vitamins, and water through the epithelial lining of the intestines into surrounding blood capillaries.

g. Compaction dehydration of undigested material and other wastes, feces.

h. Defecation elimination of feces from the body.

2. Accessory organs:

|. Large intestine

5. Mesenteries are double layers of the parietal peritoneum that attach some digestive organs to the body wall.

6. Stomach does not absorb any significant amount of nutrients, but it does absorb aspirin and some lipid-soluble drugs. The stomach also where the digestion of proteins begins.

7. The importance of the small intestines it is where chemical digestion of food completed.

}. 6 meters

~. They are highly convoluted allowing for the body to contain them more easily.

8. The large intestines absorb the electrolytes and water from feces before defecation.

9. Bile is used in the small intestine to emulsify fat...
