Inspiration
What muscle expand the chest cavity by rotating the ribs upward, contributing to inspiration
When you breath in, it becomes larger. Conversely, it is smaller when you exhale.
chest cavity (Laryngeal cavity)
The intercostal muscles are located between the ribs. They play important roles in breathing. There are two sets of intercostal muscles, external and internal. The external intercostals contract during normal inspiration, causing the rib cage to expand out and up and thus increase the volume of the chest cavity. The internal intercostals are used during forced expiration only. When they contract, the rib cage pulled down and together, shrinking the volume of the chest cavity.
Inspiration
the air goes up to the chest cavity. Hope this helps you!
Chest cavity volume increases during inahalation, and decreases during exhalation.
The diaphragm (a sheet of muscle underneath the ribcage) and intercostal muscles (located between your ribs).
What muscle expand the chest cavity by rotating the ribs upward, contributing to inspiration
The chest cavity increases in size during inhalation
The chest cavity is where your heart, lungs, and esophagus reside. It's essentially everything located behind the chest wall, but in front of the spine, above the diaphragm and below the throat.
During exhalation the diaphragm relaxes and the chest cavity gets smaller.
When you breath in, it becomes larger. Conversely, it is smaller when you exhale.
Chest cavity
The heart is within the chest cavity. It is located medially in the chest cavity.
The function of the chest cavity is to support some internal organs. The lungs and the heart are located in the chest cavity which protects and supports them.
