The Before.
The nervous system sends signals to other body systems to prepare them for the long race. The urinary and digestive systems slow down to save energy for the race. Glucose levels rise so there is enough ATP for all the energy needed for the muscles. the mouth tends to dry to save fluids for the race. -
One Minute Into The Race
Transportation of oxygen to the muscles, elemination of metabolic wastes, and the reduction of heat is going on. They are happening by the increase of breathing to a faster pace. When running, the muscles begin to fatigue and cannot produce the amount of ATP the body needs. -
The Middle
Mary's body temperature starts to increase causeing the hypothalomus in the brain to stimulate the sweat glands in the skin. The sweat in a natura source of cooling in the body when your internal temperatue increases. The urinary system deals with loss water by slowing down the excess watr in the body. In the middle of the race she hits her comfertable stage and her body starts making ATP for energy and towards the last strech of the race her body starts to make latic acid for the muscles. -
The End
Mary feels dizzy at the end of the race because her body is pumping more blood to the muscles rather than the head. She may become dehydrated as well. Mary's heart rate and breathing rate are high because she has yet to enter the recovery period for her body to know the workout is over. Mary also only sipped water so she will not damage her kidneys or increase her blood volume which increases her blood pressure. -
10 Minutes After the Race
Parasympathetic Division of Autonomic Nervous system kicks in to help regulate the organs and brings bodily functions back to normal. She lost most of the water in her body due to sweating, so she will hydrate trying to rehydrate her body. Lactic Acid is present in the muscles making her muscles feel sore. During the hard exercise, her muscle fibers tore, so her body must grow the muscle fibers back making the muscles stronger.
