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)
Responses
The muscles begin to use carbon dioxide to power contractions.
The muscles begin to use carbon dioxide to power contractions.
The pulse and breathing rate increases to provide more oxygen.
The pulse and breathing rate increases to provide more oxygen.
The blood pressure drops because of a drop in blood volume.
The blood pressure drops because of a drop in blood volume.
The heart rate decreases to give more time for oxygen to enter.
The correct response is: The pulse and breathing rate increases to provide more oxygen.
The correct prediction would be:
The pulse and breathing rate increases to provide more oxygen.
When a person sprints across a football field and their muscles use up most of the oxygen in the blood, the body responds by increasing the pulse and breathing rate. This is because the muscles require more oxygen to sustain the intense activity. By increasing the pulse and breathing rate, the body delivers more oxygen to the muscles in order to continue powering contractions and meet the increased demand for oxygen.
