The respiratory system is the system that supplies your cells with oxygen.
Many people call it 'the breathing system', but it is much more than that.
Your digestive system breaks up the food that is ingested into Glucose, but this alone cannot feed your cells. It needs a special ingredient called Oxygen to kick start the reaction that turns Glucose into Energy. Here is the word equation: GLUCOSE + OXYGEN ----> CARBON DIOXIDE + WATER + ENERGY.
So basically, when you breathe in, you are breathing in oxygen (well, actually, you are breathing in a mixture of gases but the surplus gases are stored in the lungs to be expelled) which reacts with the Glucose in the cells to produce said products. . The waste products (Carbon Dioxide and water) are then expelled one way or another.
So this explains why we breathe harder/faster when we are exercising or doing hard labour - because your cells need more energy so your body is drawing in more oxygen so that it can respire quicker.
The parts of the respiratory system are: The lungs, the diaphragm, the trachea, bronchi and general breathing apparatus. Even though the blood is used to carry the energy to cells, it isn't counted as part of the respiratory system. It is part of its own system, called the circulatory system, or the cardiovascular system.
the respiratory system is the system in the human body that helps u breathe. the function is that when u breathe in oxygen fills the lungs and when u breathe out u release carbon dioxide and it contract
I AM A CHILD AND I KNOW THIS!YAY FOR ME!
the respiratory system brings oxygen to the blood and removes the waste gas carbon dioxide
The respiratory system is the system that handles breathing.

The larynx belongs to the respiratory system.
no, they do not have a respiratory system

how does the respiratory system work

1. Respiratory system 2. Cardiovascular system
The lungs are part of the respiratory system! they help the circulatory by giving oxygen, but they are just respiratory.
