Document Summary
The stomach has 3 layers of muscles: gives shear action low ph causes the solid to turn more into liquid. Thick mucous layer protects inner stomach wall from acid erosion. Segmentation (smallintestine) more localized contraction of the muscles, compared to peristalsis. Peristalsis keeps food moving contraction of muscles. The stomach is a bag that churns and squeezes the food, acid (hcl) breaks the food down. Stomach wall protects themselves with a lining of mucous. The broken down food (chyme) is squeezed through the pyloric sphincter into the small intestine. Pancreas pumps out juice that neutralize stomach acid. Large intestine"s main job = extract water from waste. Fructose (already a monosaccharide, a simple sugar) does not require digestion. The fatty acid chains in a triglyceride can be different in length with different numbers of double bonds. Coconut oil is predominantly saturated fat (medium chain length). 95% of the fat we eat is in the form of triglyceride; less in phospholipids.
