The answer to this question would be phantom pain
An amputated leg sometimes still giving a fell of leg or pain even though the leg wasn't there anymore. That happened because the nerve fiber that carries the stimulus from that area is still alive. Something might induce the remnant of the nerve to send a signal of pain but the brain interprets the location to be in the removed limb.
Answer:
Higher
Explanation:
Molecules such as oxygen move from a higher concentration to a lower concentration across a semi-permeable membrane. This process is called simple diffusion.
Therefore, for oxygen to leave the alveoli and enter the blood, there would need to be a higher concentration of oxygen inside the alveoli and a lower concentration of oxygen in the blood.
