Why does the body need Oxygen?
to stay hydrated
to make glucose in photosynthesis
to stay awake in class
to make ATP energy in cellular respiration
Which of the following is the correct order of O2 movement?
heart --> lungs --> mouth --> body cells
mouth --> heart --> body cells --> lungs
mouth --> lungs --> heart --> body cells
lungs --> heart --> body cells --> mouth
What is a waste product of cellular respiration?
ATP
O2
CO2
Glucose
Which two systems work together to bring O2 into the body and CO2 out of the body?
circulatory and digestive
respiratory and circulatory
digestive and integumentary
respiratory and integumentary
Where does Oxygen go after it enters the lungs?
it moves to the mouth through exhalation
it stays in the lungs
it moves to the bloodstream through diffusion
it moves to the body cells through diffusion
Without the respiratory system, body cells would not receive Oxygen from the air. How would an organism make energy in the cells?
cells would make lungs to get O2 to make ATP
cells would not change, they can still get O2 from the bloodstream
cells would not make energy without O2
cells would do anaerobic respiration to make ATP without O2
Where does Oxygen go after it enters the lungs?
it moves to the mouth through exhalation
it stays in the lungs
it moves to the bloodstream through diffusion
it moves to the body cells through diffusion
