Cardiovascular, Respiratory and Nervous System Review

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.

What does our body use oxygen for in cellular respiration?

• A. to react with glucose in order to get energy

• B. To absorb the CO2

• C. To react with water

• D. To help blood flow

Notice that some points on the graph are numbered. When was Patricia most likely running on the treadmill?

• from point 2 to point 4

• from point 1 to point 5

• from point 3 to point 4

• from point 3 to point 5

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.

• Her muscles needed more glucose and oxygen because they were working harder.

The atria are the “upstairs” chambers of the heart and these parts are the “downstairs” chambers ___________.

• veins

• valves

• ventricles

• blood

Which list below correctly describes the sequence that blood takes as it travels through the body?

• heart-lungs-body-heart

• heart-body-lungs-heart

• heart-lungs- body-lungs

• heart-lungs-heart-body

How is the function of arteries different from that of veins?

• Arteries carry red blood; veins carry blue blood.

• Arteries carry blood to the body cells; veins carry blood to the lungs.

• Arteries carry blood away from the heart; veins carry blood to the heart.

• Arteries carry blood to the heart; veins carry blood away from the heart.

Tyler pulled his arm and hand away from a hot light bulb. Which list below correctly traces the path of the nerve impulse ?

• sensory neuron--brain--motor neurons

• sensory neuron--spinal cord--motor neurons

• sensory neuron--motor neurons--brain--spinal cord

• sensory neuron--spinal cord--brain--spinal cord--motor neurons

Which two systems of the body directly interact to produce a reflex action?

• nervous and muscular

• circulatory and nervous

• circulatory and muscular

• circulatory and digestive

From the diagram above (reflex response), why does this action react faster than you moving your leg normally?

• A. You are feeling pain so you move faster

• B. Your message stops at your brain to move the leg in response

• C. Your message stops at your spine to move the leg in response

• D. You are only using your sensory neurons to move the leg in response
