LAB 1 Background and Hypothesis: I know I haven’t passed the lab 1 H and B but I really do not want to lose points again just for the fact I didn’t get it done in time. I already lost -5 pts and I really don’t want to lose -20 pts. So I am just gonna go on a whim here and just get it done through here so it doesn’t automatically fail me without me at least trying. Background: Test to see if people who are Left Handed would be left thumb dominant and compare to see people who are Right Handed

The function of the digestive system is to absorb and assimilate key nutrients which are required to maintain and regulate other systems in the body. Enzymes secreted within the digestive system have a role of breaking down food from proteins into amino acids‚ starch into glucose and fats into a mixture of fatty acids and glycerol. The main function of the respiratory system is to inhale oxygen and exhale the waste product carbon dioxide. Oxygen is breathed through the mouth and nostrils into the

The human body has to be controlled from advanced systems internally of which connect in order to function effectively. There are ten main systems within the body of which all perform various activities and all interrelate with at least one other system; the nervous system. The most complex of all body systems‚ the nervous system controls all functions within the body. The main function of the respiratory system is to inhale oxygen and exhale the waste product carbon dioxide. Oxygen is breathed

The human digestive system‚ like those of other vertebrates‚ is built around an alimentary canal - a one way tube that passes through the body. The function of the digestive system is to convert foods into simple molecules that can be absorbed and used by the cells of the body. Food enters the mouth‚ where the work of the digestive system begins. Chewing‚ which takes place in the mouth‚ seems simple enough - teeth tear and crush the moistened food to a fine paste until it is ready to be swallowed

The Digestive Track The BIG MAC is placed in the mouth. The bread is mainly starch‚ the special sauce is mainly fat‚ lettuce‚ pickles‚ and onions are niacin. The beef patties are protein‚and cheeseis a form of calcium‚ fat‚ and protein. The piece of the BIG MAC is placed in the mouth and chewed‚ the starch is being digested by saliva. The starch becomes a kind of sugar which is used as a nourishment for the cells. Saliva changes food to a form that can be used by the body called enzymes.
