input: Please answer the following: What is the final step of the following process: - Air is taken into the body via the nose or mouth - The air travels into the windpipe - The windpipe divides the air to the two lungs via the bronchial tubes - The lungs oxygenate the blood in the body - Carbon dioxide is filtered out by every cell in the body - The carbon dioxide is carried back to the lungs via the bloodstream
++++++++++
output: The carbon dioxide is exhaled.

input question: What is the final step of the following process: - The flu virus has receptors, which are like viral Velcro, on the surface of the virus particle - The receptors will lock onto a target cell using these chemical receptors on the surface, which docks onto the cell surface - The receptors then go into the cell - The receptors use it like a factory - The receptors take it over and make it produce thousands or in some cases millions of copies of new viruses - The copies come streaming out of the cell???
output answer: The copies infect other cells to make more viruses, or they escape from the body and infect a new victim

input question: What is the final step of the following process: - A person breathes in oxygen - The oxygen passes through the bronchial tubes to the lungs - The oxygen is moved into the bloodstream - Circulates through the body - The cells in the body exchange the oxygen with carbon dioxide - The bloodstream carries the carbon dioxide back to the lungs???
output answer:
The lungs expel the carbon dioxide through the nose and mouth.
