The Mechanics Of Breathing Flashcards
What does inhalation/inspiration mean
The process of breathing in
What does exhalation/expiration mean
The process of breathing out
What happens to the chest cavity and diaphragm as we breath in
Chest cavity changed in size and shape
The diaphragm flattens and moves downwards
What muscles contract when we breath in and what does they do to other body parts
The intercostal muscles contract and the raise the ribs up and sternum is pushed out
What happens to the chest cavity as the intercostal muscles contract and we breath in
They get bigger and the air pressure is reduced
Which causes the air to be sucked into the lungs
What happens to our body when we breath out
The diaphragm becomes dome sharpened and the intercostal muscles relax which lowers the ribs and the sternum
This makes the chest cavity smaller and increases the air pressure in it causing air to be pushed out
What body parts do we use when breathing in and out
Diaphragm Ribs Lungs Chest cavity Intercostal muscles
What happens when you expertise to your lungs
The work a lot harder and they need to expand and contract a lot more to get oxygen to the cells and co2 out the body so inhaling and exhaling is down a lot more often
What paired muscles in the side of beck help to do what, when in spring
Pectorals and sternocleidomastoid help to assist raising the sternum
What do the abdominal do when you expire
Pull the ribcage down to force air out
What is consolidation
The build up of a liquid in the lungs tissue
