The diaphragm will contract and become flat instead of curved. This will give more air in the ribcage for the lungs, which now have a lower pressure (x amount of particles in a larger space). This draws air in from the outside as the pressure is higher outside of the lungs. Hence why you breathe. The ribcage will push up and outward as the lungs expand.
What else can I help you with?
what is the act of taking air in as the diaphragm contracts and pulls downward?
Inhalation
What is act of taking in air as the diaphragm contract and pulls downward called?
The act of taking in air as the diaphragm contracts and moves downward is called inhalation. During inhalation, the chest cavity expands, creating a vacuum that draws air into the lungs. This process allows for oxygen to enter the body and be distributed to the cells for respiration.
What two statements describe how the diaphragm works?
The diaphragm is a dome-shaped muscle that contracts and relaxes during breathing. When it contracts, it flattens out and pulls downwards, creating a vacuum that expands the chest cavity and draws air into the lungs. When the diaphragm relaxes, it moves back to its original dome shape, pushing air out of the lungs as the chest cavity decreases in size. This process of contracting and relaxing allows for inhalation and exhalation, enabling breathing to occur.
What do you do when you breath in and out?
To breathe in your chest expands, creating a vacuum and thus drawing new air in. The new air contains a lot of oxygen (20%). To breathe out the chest contracts , forcing out the used air from which some of the oxygen has been removed and been replaced by carbon dioxide.
When the muscle contracts what happens to the tendon and bone?
When the muscle contracts, the tendon pulls on the bone to create movement. The tendon is the connective tissue that attaches the muscle to the bone, so when the muscle contracts, it exerts force on the tendon, which in turn moves the bone.
Is the act of taking air in as the diaphragm contracts and pulls downward?
Inhalation
what is the act of taking air in as the diaphragm contracts and pulls downward?

What is act of taking in air as the diaphragm contract and pulls downward called?
The act of taking in air as the diaphragm contracts and moves downward is called inhalation. During inhalation, the chest cavity expands, creating a vacuum that draws air into the lungs. This process allows for oxygen to enter the body and be distributed to the cells for respiration.
How does diaphragm help during the inhaling and exhaling process?
During inhalation, the diaphragm contracts and moves downward, allowing the lungs to expand and fill with air. This creates a vacuum in the chest cavity, drawing air into the lungs. During exhalation, the diaphragm relaxes and moves upward, forcing air out of the lungs.
How do the lungs move?
The diaphragm is a strong wall of muscle on the bottom of the chest cavity. As this wall of muscle expands downward, a vacuum is created which pulls air into the lungs. As the diaphragm returns to it's original position, air is pushed out of the lungs.
How does the diaphran function?
The diaphragm is the main muscle used when breathing in. During the diaphragmic contraction, the diaphragm pushes downward and pulls on the pleural cavity which allows air to flow into the lungs.
What is the job of the diaphram?
The major muscle that the body uses for breathing The above answer is of course correct for the thoracic diaphragm but there are others for example the pelvic diaphragm. A diaphragm is a domed muscular wall the reperates to regions. When is contracts it flattens to increase pressure on the inside of the dome and decrease pressure on the outside of the dome. In the case of the pelvic diaphragm is domes downards and contracts to resisf the increased pressure from the thoracic diaphragm on the abdomen during inhalation.
What happens to the diaphragm when a person inhales?
The diafragm moves downward and the intercostal muscles contract pushing the chest outward and upward causing negative pressure in the lung structure - air will allways move from a high pressure area to a low pressure area, hence, into the lungs.
What part of the body helps us breathe in?
The diaphragm relaxes to help squeeze the air out of your lungs. When the diaphragm contracts, it flattens and pulls air into your lungs. When it relaxes into its dome-shaped position, air is pushed out.
What happens to your lungs in normal breathing?
When you breathe, your diaphragm pulls downward which should create a vacuum within the chest cavity, but instead of that happening, your lungs expand because it is connected to your airway. When you breathe out, your lungs collapse due to your diaphragm returning to its original position.
When a muscle contracts, it pulls with what force?
When a muscle contracts, it pulls with a force generated by the muscle fibers contracting and shortening.
Does the diaphragm move up on inhalation?
No, the diaphragm moves down during inhalation. This action increases the space in the chest cavity, allowing the lungs to expand and fill with air. The downward movement of the diaphragm creates negative pressure in the chest, which draws air into the lungs.
