Q

in the most simplest terms what is the respiratory ?

A

The respiratory system is the part of your body that helps you breathe.

Q

how does the respiratory system work ?

A
  • Breathing in: You take in air through your nose or mouth. The air goes down your throat into your lungs
  • Lungs: Inside your lungs, there are tiny air sacs called alveoli, where oxygen from the air moves into your blood
  • Oxygen transport: Your blood carries this oxygen to the rest of your body so your cells can use it for energy
  • Breathing out: Your body makes a waste gas called carbon dioxide, which you breathe out when you exhale

Q

define quiet breathing :

A

is the normal, relaxed breathing you do when you’re just sitting or resting. You don’t think about it, and it keeps your body working by getting oxygen and releasing carbon dioxide. It’s gentle and automatic

is the type of breathing you use when you’re talking. You take in more air than usual so you can say longer sentences, and you control how you let the air out to help with speaking. It requires more effort and control than quiet breathing
