Glucose&oxygen react together to produce carbonn dioxide& water. Known as aerobic respiration.
Glucose is carried around in blood plasma(yellow liquid). Dissolved glucose can diffuse into four capillaries.
Carbon dioxide produced during respiration diffuses out of cells&across into plasma. Blood carries it to the lungs&then diffuses across the walls of the alveoli&then it is ready to be exhaled.
The respiratory system contains organs that allow it to get the oxygen we need&to remove carbon dioxide we don't need.
Movements of the ribs, rib muscles&diaphragm allow air into&out of the lungs. This is called BREATHING or VENTILATION, NOT RESPIRATION. We inhale&exhale.
