The Voyage of Oxygen -- from the atmosphere (air) to the mitochondria
Instructions: You are going to make a cartoon illustrating the ‘voyage of oxygen gas.’ Oxygen will start
in the air then move into the lungs, then it will diffuse into the blood cells and be transport into the
mitochondria in muscle cells, then it will be convert into carbon dioxide and water through cellular
respiration.
You will make 8 slides in your cartoons on the given pieces of paper. Each slide should have a caption,
summarizing what is happening. These eight slides will accurately describe the following steps in the
voyage of oxygen:








Slide 1: Oxygen gas is in the atmosphere (air) living freely.
Slide 2: An animal takes an inhale. Illustration and label the following features of an inhalation:
o Show the Movement of diaphragm and rib cage, internal intercostal muscles and external
intercostal muscles
o Show how the volume of the chest cavity changes.
o Show how the changes in volume affect the pressure in the chest cavity.
o Describe in a caption how and why air moves into the lungs.
Slide 3: Oxygen gas moves into the lungs of an animal. Illustrate and label the following features:
o pharynx
o trachea
o lungs and bronchus
o bronchioles.
o Alveoli
o diaphragm
Slide 4: Show gas exchange, that is, show oxygen gas moving into the alveoli which is surround by a
network of capillaries and carbon dioxide moving out of the blood cell into the alveoli.
o Show / describe FOUR features/ characteristics/ adaptations of alveoli that allow for efficient
gas exchange.
Slide 5: Oxygen gas diffuses from the alveoli into the capillaries then into the blood cells.
o Show how many cell membranes that the oxygen molecule must diffuse through to move from
the alveolus to inside the blood cell
Slide 6: Oxygen is transport by the blood to muscle cells through veins and arteries.
o Show the diffusion of Oxygen from the blood cell through the capillaries to the muscle cell.
o Show the diffusion of carbon dioxide from muscle cell through the capillaries to the blood cell
Slide 7: Show oxygen diffusing into the mitochondria of muscle cells
Slide 8: In the mitochondria, oxygen reacts with glucose and is converted to water, carbon dioxide
(cellular aerobic respiration).
o Write the balance chemical equation for cellular respiration.
