How do inhalation and exhalation impact diaphragm movement?
During inhalation, the diaphragm contracts and moves downwards, causing the chest cavity to expand and draw air into the lungs. During exhalation, the diaphragm relaxes and moves upwards, allowing the chest cavity to decrease in size and push air out of the lungs. These movements ensure proper ventilation of the lungs.
The diaphragm contracts during what phase of respiration?
The diaphragm contracts during the inhalation phase of respiration. When it contracts, it moves downward, increasing the volume of the thoracic cavity and causing air to rush into the lungs.
Why do larynx move with deglutition?
The larynx moves during the swallowing process, or deglutition, to protect the airway from food and liquid entering the lungs. This movement helps to close off the entrance to the trachea (windpipe) by raising the larynx and epiglottis, preventing aspiration of food or liquid into the respiratory system.
Does thoracic volume increase or decrease during inhalation?
Thoracic volume increases during inhalation as the diaphragm contracts and moves downward, and the rib cage expands outward and upward. This creates more space in the thoracic cavity, allowing the lungs to expand and draw in air.
Does the thoracic cavity increase in size during inhalation?
Yes, the thoracic cavity increases in size during inhalation as the diaphragm contracts and moves downward, while the intercostal muscles contract to elevate the ribcage. This expansion creates negative pressure in the lungs, causing air to be drawn in.

What happens to the thoracic cavity during inhalation?
During inhalation, the thoracic cavity expands as the diaphragm contracts and the rib cage moves up and out. This creates more space for the lungs to expand and fill with air.
When air moves into a lung it is called?
Inhalation
Sits a-top the trachea and moves muscles to change the shape of vocal cords?
The larynx

When air moves into the lungs when the diaphragm muscles do what?
The diaphragm moves down to make the lungs expand (inhalation)
What Air moves through the larynx through the blank and then into the lungs?
