As physical activity ramps up, a person typically begins to breathe more rapidly, to sweat, and to flush red. Describe how each of these physical responses of the body is connected to the reactants and products of the process of aerobic respiration.
What will be an ideal response?
Increased respiratory rate occurs as a result of increased tissue needs for oxygen. Sweating rids the body of excess water that is formed during the ETC of cellular respiration. Flushing skin aids the body in maintaining homeostatic temperature by bringing heat to its surface so that they heat may evaporate, cooling the body.
