What else can I help you with?
What does the rib muscles and diaphragm contract do to the chest cavity?
The space in your chest cavity increases.
What is it called when the diaphragm relaxes and the chest cavity becomes smaller?
During exhalation the diaphragm relaxes and the chest cavity gets smaller.
What parts of the respiratory system when you inhale?
answer: diaphragm at the bottom of the chest cavity is a muscle called the diaphragm. when the diapragm contracts, the chest cavity becomes larger.
What muscle expand chest cavity upward during inspiration?
The diaphragm (a sheet of muscle underneath the ribcage) and intercostal muscles (located between your ribs).
What part of the respiratory system contracts when you inhale?
answer: diaphragm at the bottom of the chest cavity is a muscle called the diaphragm. when the diapragm contracts, the chest cavity becomes larger.
What makes the chest cavity larger when you inhale?
When you inhale, the diaphragm muscle contracts and moves downward, and the rib cage expands as the intercostal muscles between the ribs contract. This creates more space in the chest cavity, allowing the lungs to expand and fill with air.
Rib muscles and diaphragm contract making the chest cavity?
Increases
What muscles are responsible for the changes in the chest cavity volume?
The primary muscles responsible for changes in chest cavity volume are the diaphragm and the intercostal muscles. The diaphragm contracts and moves downward during inhalation, increasing the volume of the thoracic cavity and allowing air to flow into the lungs. The intercostal muscles, located between the ribs, assist by elevating the rib cage, further expanding the chest cavity. During exhalation, these muscles relax, decreasing the volume of the chest cavity and expelling air from the lungs.
The contraction of the diaphragm and rib muscles and expansion of the chest cavity are part of which process?
Inhalation
Which body part responsible for making the chest cavity smaller when you exhale?
the diaphragm, ribs, chest muscles, and sternum.
Why does the respiratory muscles increase in strength?
the diaphragm and intercostal muscles increase in strength allowing for greater expansion of the chest cavity
Which organs cause inhalation and exhalation to occur?
Inhalation is caused by the diaphragm and external intercostal muscles contracting, which increases the volume of the chest cavity. Exhalation is primarily a passive process, where the diaphragm and external intercostal muscles relax, allowing the chest cavity to decrease in volume and air to be expelled from the lungs.
