What is Heart Rate?
The number of times your heart beats.
The number of times your heart beats per minute.
The maximum amount of times your heart should be.
The amount of times your heart should beat while exercising.
Which statement is MOST TRUE about the movement of oxygen molecules between the lungs and cells of the body?
A. Oxygen molecules enter and leave the body by way of lungs, but they do not move between the lungs and the blood.
B. Most oxygen molecules move from cells of the body to the lungs by moving through the circulatory system and then leaving the circulatory system by way of capillaries at the lungs.
C. Most oxygen molecules move from the lungs directly to the body by way of special respiratory tubes where the oxygen molecules mix with the blood.
D. Most oxygen molecules move from the lungs to cells in the body by entering microscopically small blood vessels (capillaries) and then move to the heart which pumps it to the cells of the body.
Which statement best describes why your heart rate increases while exercising?
Her bones needed more oxygen because they were moving faster.
Her stomach needed more oxygen because it was digesting food faster.
Her brain needed more blood to coordinate her rapid exercise movements.
