Answer:

Carbon dioxide moves from the blood into the cells.

The statement 'carbon dioxide moves from the blood into the cells' is FALSE.

  • During respiration (inhalation), oxygen from the air passes from the lungs to the bloodstream where is transported by red blood cells to all cells of the body.

  • Red blood cells transport oxygen and nutrients to all cells of the body in order to carry out a series of metabolic reactions known as cellular respiration.

  • Subsequently, carbon dioxide moves from all body cells to red blood cells where this waste product of cellular respiration is transported to the lungs in order to be exhaled.

In conclusion, the statement 'carbon dioxide moves from the blood into the cells' is FALSE.
