Hugs make you whole

By now, you should know what the different parts of the respiratory system are, can you name some of the parts of the respiratory system?

You would have gone over the parts and functions of the respiratory system back in Grade 6

Multiple Choice

TRUE or FALSE?

It is better to breathe in through the mouth because it allows us to take in more air.

• TRUE

• FALSE

Why we breathe through the nose and not the mouth

If mouth breathing were better, why do we breathe through the nose?

Breathing through the nose provides us with THREE main benefits:

• FILTRATION: Nose hairs prevent foreign particles from reaching the lower respiratory system

• TEMPERATURE REGULATION: The nasal cavity has a lot of blood vessels​ to warm up or cool down the air

• MOISTURE: The temperature regulation also helps moisten the air, preventing cold air from drying out the respiratory system​

Multiple Choice

TRUE or FALSE?

The types of gasses we breathe in are the same as the types of gasses we breath out.

• DEFINITELY TRUE

• I don't like thinking about it

• OBVIOUSLY FALSE

While our body exhales a lot of carbon dioxide, all other gasses that we inhaled but did not use is also released when we exhale.​

While we breathe in combination of different gasses, it is mainly oxygen that our body absorbs into our body and the bloodstream.​

We inhale and exhale oxygen, carbon dioxide, and all other gasses in the air

Why do we still exhale oxygen if our body absorbs it when we inhale?​

Why do you think we still exhale oxygen even though our body absorbs the oxygen?
