Slide 8 - Quiz
Respiratory muscles
- Chest breathing: intercostal muscles.
- Abdominal breathing: diaphragm.
Slide 9 - Diapositive
2 muscles involved in breathing:
- intercostal muscles
- diaphragm
Slide 10 - Diapositive
Breathing in (inhalation)
-Intercostal muscles - contract
-Diaphragm muscles - contract
-Increases volume of thorax
- Pressure thorax decreases
- External air pressure is greater
air moves inside
Slide 11 - Diapositive
Breathing out (exhalation)
-Intercostal muscles - relax
-Diaphragm muscles - relax
-Decrease volume of thorax
- Pressure thorax increases
- Internal pressure is greater air forced out
Slide 12 - Diapositive
Two ways of breathing
Inhalation and exhalation
Thoracic breathing abdominal breathing
Slide 13 - Diapositive
Thoracic inhalation:
Intercostal muscles contract
Ribs move upward and forward
Chest becomes bigger
Lungs become bigger
air is sucked into the lungs
Slide 14 - Diapositive
Thoracic exhalation:
Intercostal muscles relax
Ribs move downward and backward
Chest becomes smaller
Lungs become smaller
Air is pushed out of the lungs
Slide 15 - Diapositive
Abdominal inhalation:
Abdominal muscles contract
The diaphragm contracts and moves down
Chest becomes bigger
Lungs become bigger
Air is sucked into the lungs
Slide 16 - Diapositive
Abdominal exhalation:
Abdominal muscles relax
The diaphragm moves up
Chest becomes smaller
Lungs become smaller
Air is pushed out of the lungs
