You don't only "breath in air, and breath out air,"
You breath in Oxygen and let out Carbon Dioxide. Passes to the diaphragm and the lungs, inhale oxygen, it goes through your body, exhale Carbon Dioxide, From which the body has made when inhaled.
it will increase
Pressure within the thorax decreases and air is drawn into the lungs
both you can start with breathing out or by breathing in
respiration happens inside the body and breathing happens outside the body
you first breath in and then you breath out
Your breathing becomes deeper and faster.
During external respiration, carbon dioxide is released from the body by diffusing from the blood into the alveoli in the lungs. It is then exhaled out of the body during the process of breathing.
Increases due to greater oxygen demands and a rising blood CO2 concentration (PCO2).
Hopefully, it continues.
It speeds up.
normal breathing is nice and easy while breathing during an asthma attack is difficult and doesnt allow you to fully use your airways.
Sympathetic activation almost always speeds up any system. In this case breathing rate.
