☻Term 2 Information Report☻ Your Lungs and Breathing Have you ever thought of what keeps your blood healthy? Or what lets you breathe? Well it’s the respiratory system’s job to do all this things.

What’s the respiratory system you may ask. The respiratory system is made up of the nose, the lungs and the trachea (the windpipe).

I bet you didn’t know where the air goes once you breathe. The air will go into the nose. The nose is like a filter. It lets air in but dust will be stopped by the nose hairs. The air will be taken down into the lungs through the trachea. In the lungs the gases will be separated. The carbon dioxide and other gases will be taken out when you exhale (breathe out). Oxygen on the other hand will be put in the bloodstream.

Adults, like your mum and dad, will take less breaths in a minute because they have bigger lungs. They also take deeper breaths. They need the extra air because of the bigger supply of blood.

Your average breath has the speed of 8kph. Your sneeze speed can go much faster. This is due to pressure. Air builds up in your nose then released into air.

Hiccups are caused by the diaphragm. The diaphragm jets up sharply creating less space in the lungs. The air is forced in out into the trachea and into the mouth. As the air goes out of the mouth it is causing friction. Friction is the power of two surfaces. Take a toy car. It will go down a hill faster if its wheel is covered with ice. The ice is slipperier than rubber so it slides down the hill. Back to the hiccups, this is caused between the air and your mouth. This causes a ‘hi’ sound. This also caused when you cough. But because the mouth is larger it makes a different noise.
