Answer:
decrease in o2 in air effects the movement of o2 in the body,
Explanation:
because the less o2 in the atmosphere, the muscle system of the human body will not respond correctly for movement. we wud become sluggish, and less active to conserve o2. example; moving to a higher altitude has less o2..
A decrease in the percent of oxygen in the air affect the movement of oxygen in the body would not affect the rate of diffusion into the blood because there would be no difference between the partial pressures of the air and blood.
"Diffusion is the movement of a substance from an area of high concentration to an area of lower concentration. Diffusion is an important process for living things - it is how substances move in and out of cells."
"The term partial pressure is used when we have a mixture of two or several gases in the same volume, and it expresses the pressure that is caused by each of the individual gases in the mixture."
"This large difference in partial pressure creates a very strong pressure gradient that causes oxygen to rapidly cross the respiratory membrane from the alveoli into the blood. The partial pressure of carbon dioxide is also different between the alveolar air and the blood of the capillary."
