Document Summary
Digestive system: digestion: molecules are chemically broken down to smaller molecules by enzymes in the lumen of the gi, kidneys excrete more bicarbonate ions and fewer h ions tract. Hcl (stomach) bile (liver) nahco3 (pancreas: physical and chemical break down nutrients into absorbable unit, physical digestion (chewing, mixing, 2. Chemical digestion (enzyme catalyzed: polysaccharides monosaccharides, proteins amino acids fats glycerol + fatty acids, absorption, transfer of digested materials across the digestive epithelium intestinal lumen blood or lymph. State the names of the organs that makeup the digestive tract, from beginning to end: gastrointestinal (gi) tract, hollow tube, 15 feet long, mouth pharynx esophagus stomach small intestine colon rectum anus.
