Cardiopulmonary System

The functions of the human cardiopulmonary system can be broken down into two, circulatory system and the respiratory system. The main goal of these two systems is to maintain homeostasis in our body. Homeostasis can be described as a type of condition where the internal continuity of an individual has to keep steadiness, regardless of any external changes from the outside environment. External changes from the outside environment may include factors such as excitement, stress, exercise, diet, and much more. Exercise can be carried out because the human body can endure a high level of exercise during a prolonged period of time. In this experiment, we will focus on how exercise, in particular, affects the cardiopulmonary physiology of boys across different body mass indexes.

Exercise places strenuous activity on the human body. When an individual exercise, the blood flow must level up to the demands being made on the individual’s muscles, heart, and lungs. Blood flow increases so that the blood does not clot and so that it can supply

If we imagine that an individual has begun exercising, the oxygen uptake increases because there is a higher demand for energy. Oxygen is the ultimate source of energy that allows ATP to be generated. More ATP must be made in order for homeostasis to be maintained. After a prolonged period of exercise, lactic acid accumulation begins to occur in the tissues of the body because the energy for oxygen uptake can no longer be supplied after a certain period of time of exercise. When the individual ends exercising, it takes time for the oxygen uptake to return to its resting level because the lactic acid that had accumulated in the tissues must be broken down into CO2 and H2O. The individual breathes deeply during this time because heavy breaths of oxygen must be taken in for the lactic acid to be broken
