This is an excerpt from the paper...

Digestion is one of the body’s many processes. Its purpose is to break down food into chemicals so that it may be absorbed by the cells of the body in order to maintain healthy functioning. When we ingest or eat food, we take nutrients from the environment that must be broken down into smaller molecules before the body may utilize them. We begin this process when we insert food into the mouth where chewing or mastication begins the breakdown process, aided by the salivary glands which secret enzymes which catalyze molecule breakdown. If we decide to eat a bacon, lettuce, and tomato sandwich, we are eating fiber, fats, protein, sugars, and carbohydrates. Our body begins secreting digestive enzymes the moment we see, smell, and taste food.

The wheat bread is fiber and passes pretty much through the body without being digested as we have no enzymes that breakdown cellulose or fiber, unlike other animals. This is also why lettuce which is primarily cellulose passes through the digestive tract fairly unchanged. Mayonnaise, bacon, and tomato, on the other hand, set off the body’s digestive processes. When we smell the sandwich digestive enzymes are releases in the mouth where the they help breakdown the food we chew or masticate. Amylase is the enzyme that breaks down carbohydrates from mayonnaise, bacon, and tomato, and turns them into starch. Our tongue helps shape the food into a bolus or ball that consists of the chewed foo

en. It exits the body through exhaling via the same pathway oxygen entered the body. However, the diaphragm is important in the expulsion of carbon dioxide as well as the intake of oxygen. The diaphragm is a layer of muscles that sits at the base of the chest cavity. When the diaphragm is in a contracted state, air is pulled into the chest cavity. When the diaphragm relaxes, it helps push carbon dioxide out of the chest cavity. Endocrine glands secrete hormones which help aid bodily functions and processes. One such gland important in the respiratory process is the thyroid gland. The thyroid gland produces thyroxin and calcitonin, but only thyroxin is proven to aid the respiration process. Thyroxin regulates the basal metabolic rate (BMR), i.e. cell respiration. Thus, the production of hormones has an impact on breathing and cellular respiration. Problems with hormone secretion often interfere with bodily processes in a deleterious manner, particular if too little or too much of a hormone is manufactured by the endocrine gland responsible for its production. Like the digestive process, however, the respiratory process equates to the chemical conversion of molecules into energy and nutrients. QUESTION THREE When huma
