Dear Student,
1. The ciliated mucus membrane of trachea moves the mucus containing the dust particles or foreign matter caught by cilia back to the pharynx and it is swallowed there. Our body will reabsorb most of the mucus itself. Dirt, dust, and debris are passed out of your system, and any bacteria are killed by your stomach acids.
2. When we sneeze, our body produces pressure in our respiratory system. This pressure level is of 1 pound-force per square inch in the windpipe. The sneeze can travel up to 100 m/h and create upwards of 100,000 droplets.
3. The alveoli is where gas exchange (Oxygen for Carbon Dioxide) occurs and could cover a tennis court if you spread them out on the ground.
4. Oxygen in the alveoli move into the bloodstream through a process called Diffusion.
Kindly post the different questions in different thread.
Regards
