Taking in air as the diaphragm contracts and pulls downward?
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 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.
Why is the plumule hook-shaped as it emerges?
The plumule hooks downward to protect the developing leaves as it pulls them out of the soil.
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 To breathe out the chest contracts , forcing out the used air from which some of the oxygen has been removed and been replaced by carbon dioxide.

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.

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.
How does diaphragm help during the inhaling and exhaling process?
When the diaphragm contracts, it pulls down and creates a vacuum in the lungs, which helps in breathing in.
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 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.
The diaphragm is important for what life process?
The diaphragm is a muscle which helps control the breathing process. When the diaphragm contracts it pulls down on the lungs (it is connected by the plueral membrane and connective tissue.) this creates space for the air to be forced into the lungs . This is because there is greater pressure inside the lungs than outside the lungs, resulting in air rushing into the lungs, and vice versa when the diaphragm relaxes.
