Question

A person sprints across a football field to make the touchdown. The person’s muscles use up most of the oxygen in the blood to accomplish this. Which response do you predict would happen because of this?(1 point)

Answer 1

When a person sprints and their muscles use up most of the oxygen in the blood, one predicted response is an increase in breathing rate and depth. This physiological response occurs to bring more oxygen into the body to meet the heightened demand from the muscles during intense physical activity. Additionally, the body may also start to produce lactic acid due to anaerobic metabolism as oxygen levels become insufficient, which can lead to muscle fatigue.
