Digestion Problem Set 1.Heterotrophs ? an universe that requires pre-formed organic molecules for forage Autotrophs ? an beingness that lives exclusively on inorganic materials 2.Phototrophs ? organisms that cope with their zip fastener from cut Chemotrophs ? organism that captures its energy from carbon dioxide 3.Herbivores ? organisms who receive their energy from plants Carnivores ? organisms who receive their energy from former(a) organisms Saphrophytic ? organisms who receive their energy from the decomposition of otherwise organisms all-devouring(prenominal) ? organisms who receive their energy from plants and other organisms 4. A.Ingestion - Food is inserted into the literal cavity, automatically baffled scratch off by the teeth, and chemically broken round off by saliva. The smaller forage particles form a bolus, and the bolus is pushed into the throat by swallowing. The bolus is wherefore pushed into the oesophagus and down to the condense by peristalsis. B.Digestion ? Pepsin in the stomach breaks down the bolus into smaller particles creating buzzer. The chime is indeed pushed by the pyloric anatomical sphincter into the duodenum. In the duodenum, the acerb pH of the chime is neutralized. The particles ar and hence pushed into the small bowel where nutrients are absorbed by villi. The remaining over material is then pushed into the large intestine where piss and salts are absorbed. The left over fecal material is then stored until it is eliminated through and through the anus. C.

Transportation of nutrition ? The provender is pushed through the body through voluntary go across contractions same swallowing, or involuntary muscle contractions like peristalsis. D.Assimilation of food ? Refers to the wind of nutrients from smaller sub-units, which are to be used by the body. E.Oxidation of food ? Refers to the breakdown of food through catabolism. F.Storage of food ? Refers to the storage of nutrients in the form of fat deposits. G.Excretion of dotty ? Refers to the elimination of solid and liquid...
