What else can I help you with?
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.
The diaphragm contracts and the pressure in the chest cavity decreases during?
The diaphragm contracts and moves downward during inhalation, which increases the volume of the chest cavity. This decrease in pressure in the chest cavity creates a pressure difference that allows air to flow into the lungs.
When you inhale which organ contracts and moves down?
When you inhale, the diaphragm contracts and moves downward. This movement creates more space in the chest cavity, allowing the lungs to expand and fill with air.
What part of the model represent the diaphragm?
The diaphragm is the main muscle involved in breathing and is located at the bottom of the thoracic cavity. It separates the thoracic cavity from the abdominal cavity and contracts during inhalation to increase the volume of the chest cavity, allowing air to flow into the lungs.
What are the two stages of breathing?
Inhalation; in which the diaphragm expands to draw in oxygen Exhalation: in which the diaphragm contracts to expel carbon dioxide

What muscle contracts to expand the chest cavity?
The Diaphragm
When the diaphragm contracts what happens to the size of the chest cavity?
It increases.
What separates the abdomen and the chest cavity?
The diaphragm separates the chest from the abdomen and pelvis

The diaphragm contracts and the pressure in the chest cavity decreases during?
The diaphragm contracts and moves downward during inhalation, which increases the volume of the chest cavity. This decrease in pressure in the chest cavity creates a pressure difference that allows air to flow into the lungs.
Where is the diafram?
The diaphragm is located underneath the ribcage and separates the chest cavity from the abdominal cavity. It contracts and relaxes to help regulate breathing by controlling the volume of the chest cavity.
What happens when the air pressure in your chest cavity when your diaphragm contracts?
It decreases, allowing air to flow in.
What happens to the diphgram when you inhale?
The diaphragm is a convex shaped muscle (convex side within the chest cavity).When the diaphragm muscle contracts it flattens out and drops down out of the chest cavity making more room and creating a vacuum -- air then rushes into the lungs.When the diaphragm relaxes it moves back up into the chest cavity and expels the air on the lungs. During inhalation, the increased volume of the lungs causes the ribcage to expand. Inhalation - Diaphragm CONTRACTS and moves DOWN (to allow more space in the chest cavity for lungs to expand).Exhalation - Diaphragm RELAXES and moves UP (to force air out of the lungs).
When you inhale which organ contracts and moves down?
When you inhale, the diaphragm contracts and moves downward. This movement creates more space in the chest cavity, allowing the lungs to expand and fill with air.
What takes place you initate and exhale?
When you inhale, your diaphragm contracts and moves downward, expanding the chest cavity and drawing air into the lungs. The oxygen in the air is then exchanged with carbon dioxide in the blood. When you exhale, the diaphragm relaxes and moves upward, compressing the chest cavity and pushing air out of the lungs.
Is it true that the diaphragm is flat?
Yes, in its relaxed state, the diaphragm is dome-shaped. When it contracts during breathing, it flattens out to expand the chest cavity and facilitate inhalation.
