1 38.2 Animal Nutrition Human Digestion
2 Objectives Distinguish intracellular from extracellular digestion Examine how the digestive system evolves across the phyla Identify the components of the human digestive system and discuss their functions Explain how form fits function by citing specific examples from the digestive system
3 Nutritional Requirements Animals are heterotrophs need to feed for - fuel (for production of ATP) - raw materials (carbon source for synthesis) - essential nutrients (stuff animals cannot make) - elements (N, P, Fe, Na, K, Ca, etc.)
4 Animals feature=player_embedded&v=wd- QnKlfZHI
5 Processing Food Cavity - digest food inside specialized cells - nutrients diffuse into other cells Gastrovascular cavities Intracellular digestion
6 Digestive tracts - many invertebrates and all vertebrates - digest food in a tube - food moves in 1 direction - extracellular digestion
7 Path of Food Specialized structures - breaks food down 1 step at a time - no need for eating all the time!
8
9 Mouth mechanical digestion - teeth break up food chemical digestion (saliva) - amylase digests starch - mucus protects soft lining of digestive system - buffers neutralizes acid to prevent tooth decay - anti-bacterial chemicals kill bacteria that enter mouth with food All that in spit!
10 Swallowing (& not choking) Esophagus - epiglottis closes trachea (windpipe) when swallowing - involuntary muscle contractions to move food along (peristalsis)
11 Stomach - hydrochloric acid - kills bacteria - activates pepsin à digests protein - no carbohydrate digestion! Why? - chyme squirts into small intestine thru pyloric valve - can store ~2 L of food! Inside the Stomach v=-u5jyodrvng
12 Ulcers caused by stress? most caused by bacterial infection of stomach (H. pylori bacteria) Treatment? Colonized by H. pylori inflammation of stomach H. pylori Free of H. pylori inflammation of esophagus inflammatory proteins (CagA) cell damaging proteins (VacA) cytokines helper T cells neutrophil cells white blood cells
13 Small Intestine Duodenum - digestive enzymes enter From pancreas: - amylase digest carbohydrates - trypsin digest proteins - lipase, bile from liver digest lipids - nutrients move into body cells by diffusion and active transport
14 Absorption in Small Intestines villi and microvilli (finger-like projections) Form fits function?
15 Absorption by Small Intestines
16 Liver Stomach Gallbladder Descending Colon Ascending Colon Small Intestine
17 Pancreas, Liver, Gallbladder liver produces bile to break up fats gallbladder only stores bile Inside the Human Body watch? v=hdrxuizbpei&list=pl76d4 ADE71CF274A1 Pancreas produces - enzymes that digest all 4 types of biomolecules - hormones to regulate blood sugar levels - sodium bicarbonate to neutralize stomach acids. Why?
18 Large Intestines (Colon) ~9 L of water is used every day in digestive juices need to reabsorb water! > 90% of water reabsorbed! not enough water reabsorbed? too much water reabsorbed? reabsorb by diffusion
19
20 You ve got company! E. coli digests cellulose, produces vitamins (K and B) generate gases (methane, hydrogen sulfide)
21 Mouth break up food digest starch kill germs moisten food Liver produces bile stored in gall bladder break up fats Pancreas produce enzymes digest proteins, starch Stomach kills germs break up food digest proteins store food small intestines breakdown food - proteins - starch - fats absorb nutrients large intestines absorb water
22 Appendix

24 Different diets, different bodies adaptations of herbivore vs. carnivore?
