What is the Respiratory System?
All living things need oxygen to survive and oxygen is a gas found in the air. The main reason we need to take in oxygen is that oxygen helps our body turn food into energy which is needed for us to survive. The Respiratory System is the one that makes this possible!
The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. It works together with other parts of our body like the circulatory system to deliver oxygen to the rest of our body which we need to carry out our daily activities!
We need oxygen as we go about our daily activities
Ever wonder why your heart beats faster when you are doing exercises? That’s because your body needs more oxygen and nutrients when you are exercising! Your heart needs to beats faster to transfer blood faster to the rest of the body!
Fun fact: Do you know that a newborn breath up to 44 times a minute while an adult only breathes 16 times a minute? You also breathe a lot slower when you are sleeping because your body needs less oxygen.
The organs that make up the respiratory system:
- air tubes
- air sacs (alveoli)
