Exhalation occurs when what relaxes?
The lungs don't actually contract. all the work is done by muscles in the chest.When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity. The intercostal muscles between the ribs also relax to reduce the space in the chest cavity.As the space in the chest cavity gets smaller, air rich in carbon dioxide is forced out of your lungs and windpipe, and then out of your nose or mouth.
Which reflex is involve during inhalation and expiration?
The diaphragm and intercostal muscles are involved in the process of inhalation and expiration. During inhalation, the diaphragm contracts and moves downward while the intercostal muscles expand the rib cage. This creates more space in the chest cavity, allowing the lungs to expand and fill with air. During expiration, the diaphragm and intercostal muscles relax, causing the chest cavity to decrease in size and the lungs to expel air.
What is the role diaphragm during inhalaton and exhalation?
during the exhalation phase, the diaphragm relaxes, that is resuming its dome shaped position. The intercostal muscle likewise relax and the rib cage moves down deflate . ACHECHE from:Alkenneth Angelico O. Alderite
What important structures are found in 6th intercostal space?
In the 6th intercostal space, important structures found include the internal mammary artery and vein, and the intercostal muscles and nerves. Additionally, in the left 6th intercostal space, the cardiac apex is located.
How do the ribs rise up and fall down?
The ribs rise up during inhalation when the diaphragm contracts and moves downward, creating more space in the chest cavity. This causes the ribs to move up and outwards. During exhalation, the diaphragm relaxes and moves back up, while the ribs move downward and inwards to decrease the space in the chest cavity.
What other muscle move outward to give the lungs more space?
Internal Intercostals (Depress, assist in exhalation) Diaphragm (Prime mover of exhalation) When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity. The intercostal muscles between the ribs also relax to reduce the space in the chest cavity.

When the body breathes in and out what contracts and flattens to give your lungs room to fill up with air?
When the body breathes in and out, the diaphragm contracts and flattens to create more space in the thoracic cavity, allowing the lungs to expand and fill with air. During inhalation, the intercostal muscles between the ribs also contract, lifting the ribcage and further increasing the volume of the chest cavity. During exhalation, the diaphragm and intercostal muscles relax, pushing air out of the lungs.
How does diaphragm works during exhalation?
It contracts to decrease space in the body, thus expelling air from the body
How the diaphragm works during exhalation?

What happens when the diaphragm and the rib cage muscles relax?
The diaphragm relaxes during EXHALATION. Your diaphragm flattens when you inhale, creating more space for the lungs to take in more air.
Which reflex is involve during inhalation and expiration?
The diaphragm and intercostal muscles are involved in the process of inhalation and expiration. During inhalation, the diaphragm contracts and moves downward while the intercostal muscles expand the rib cage. This creates more space in the chest cavity, allowing the lungs to expand and fill with air. During expiration, the diaphragm and intercostal muscles relax, causing the chest cavity to decrease in size and the lungs to expel air.
What does the diaphragm muscle do when air moves into the lungs?
The diaphragm moves down to make the lungs expand (inhalation)

Where would you place the stethoscope for the closure of the tricuspid valve?
In the forth intercostal space, right to the sternum, probably.
What important structures are found in 6th intercostal space?
In the 6th intercostal space, important structures found include the internal mammary artery and vein, and the intercostal muscles and nerves. Additionally, in the left 6th intercostal space, the cardiac apex is located.
Does the diaphragm deal with inspiration or expiration?
The diaphragm primarily deals with inspiration. When the diaphragm contracts and moves downward, it creates more space in the chest cavity, allowing air to flow into the lungs. During expiration, the diaphragm relaxes and moves upward passively as the air is forced out of the lungs.
