Respuesta
Intercostal muscles contract to elevate the sternum and rib cage. The diaphragm contracts downward and flattens.
Nothing. It does not involve muscles contracting.
Intercostal muscles and diaphragm relax
The intercostal muscles and diaphragm recoil due to the elasticity of lung tissue
Pregunta 10
Pregunta
What happens to the intercostal muscles and diaphragm on expiration?
Image:

Respuesta
Nothing, it does not involve muscles relaxing
Intercostal muscles contract to elevate the sternum and rib cage. The diaphragm contracts downward and flattens
Intercostal muscles relax causing the rib cage to return to its original position. The diaphragm relaxes and resumes its dome shape.
The intercostal muscles relax and the diaphragm contracts to form a dome shape.
