Digestion is a process in which the food that we eat is broken down into tiny nutrients to be taken in by the body. Within the human digestive system‚ chemical and physical reactions occur that allow for the digestion and the absorption of proteins into the bloodstream. The purpose of this paper is to show how chemistry relates to the daily functions within the body. There are two types of digestion processes‚ which are called mechanical and chemical digestion. Mechanical digestion includes the

Living Digestion The first step in the journey of a sandwich is the mouth‚ where mastication occurs. The salivary glands secrete saliva which includes enzyme amylase. The teeth masticate and reduce the food into smaller pieces. The tongue moves the food around and enables swallowing. While the food is being broken into smaller pieces‚ amylase breaks down the carbohydrates found in the bread. After chewing (or mastication) is done‚ the food moves down the esophagus through peristalsis. The epiglottis

had a larger BMR). The dose of thyroxine in the syringe was therefore too small. 7. The hypophysectomized rat’s BMR increased as well‚ and once again‚ the BMR of the normal rat was still larger and so the dose was still too small. Part 3: 8. The normal rat’s BMR increased from the TSH injections. 9. The thyroidectomized rat’s BMR increased by a little but the BMR of the normal rat was still bigger and so the dose was too small. 10.

fragments. This step is made possible by the contraction of the muscle of the stomach‚ the muscularis. Composed of three layers of fibers arranged longitudinally‚ circular and oblique‚ it mixes and kneads the food. Then begins the chemical digestion. Only the digestion of proteins begins in the stomach. The mucosa contains glands that secrete gastric juices. Under normal conditions‚ the production of juices is 2 to 3 L per day. Hydrochloric acid and enzymes are also produced by cells of the stomach

Respiration‚ digestion and rocks Respiration Respiration is a chemical reaction that happens in all living cells. It is the way that energy is released from glucose‚ for our cells to use to keep us functioning. Remember that respiration is not the same as breathing (which is properly called ventilation). The glucose and oxygen react together in the cells to produce carbon dioxide and water. The reaction is called aerobic respiration because oxygen from the air is needed for it to work. Digestion
