Document Summary
There are 5 levels of body composition that we look at: 95% of our body is made up of 5 basic elements called honc hydrogen, oxygen, nitrogen, carbon. There are also other elements that make up a small percentage of the body. Na, k, cl, p, ca, s, mg: phosphorus is found in teeth, sulfur is found in proteins (disulfide bridges) Molecular level: we look at molecules like water, proteins, lipids, minerals, body weight = sum of all molecules. Component of a cell: intracellular fluids, intracellular solids. Body weight of a person = sum of all cells in the body. Composed of: sum of specific tissues that make up organs. 2f03 focuses on these specific tissues/organs: muscles, bones, adipose. Note: he doesn"t list cardiorespiratory organs because they were only there for one chapter. Looks at the outer characteristics of the body: height, size, physique. We use anthropometric techniques to measure body parts: skin fold, weight scale, etc.
