The mechanics of breathing Flashcards
Diaphram during inhaling
Flatish and flattens
Diaghram
Dome shaped muscle that separates throatic from abdominal
Interostal muscles during inhalation
Contract
Intercostal muscles during exhaltion
Relax
Intercostal muscles
Muscles under ribcage which contract or relax to allow more room for lungs
Diaphram during exhalation
Curves and pushes upward
Lungs during inhalation
Lungs expand
Lungs during inhaltion
Intercostals and diaphragm contract (flat) and rib cage moves up
What happens to volume and pressure during inhaling
Volume of the chest increases and pressure decreases
What pressure does air move in
High to low pressure
What happens to volume and pressure during exhaling
Volume of chest cavity decreases and pressure increases
What moves during exhalation
Intercostal muscles relax, diaphragm moves relaxes (moves up)
Volume of lungs decreases and pressure increases
What does a spirogpapgh represent
The amount of air that moves into lungs with each breath
What do ribs do during exhaltion
Down and in
What do ribs do when inhalting
Up and out (give more room)
