The rib cage and diaphragm protect our lungs, which are located in our chest cavity. When we inhale, our chest muscles stretch, causing our chest cavity to rise and our lungs to expand, allowing more air to enter. When we exhale, our chest cavity descends and our lungs deflate, allowing the air to escape our lungs. Our chest muscles, which allow us to control the way our lungs move, are the reason we can accomplish this efficiently.

There are many different organs that help you breath, such as the lungs and trachea. One of the main parts of breathing is your lungs, and this organ is located inside of the ribs, which is also surrounded by the chest muscles and the diaphragm. This means that when you breath and inhale, your rib cage rises, along with your lungs, while your diaphragm shifts downwards. Since there is an increase of volume where your lungs are, it causes a decrease in the internal air pressure. because the air pressure in the cavity is less then the pressure in the environment, the air rushes to the lungs to equalize the pressure. When you exhale, the rib cage contracts, making it lower, causing your diaphragm to move upwards. This motion decreases the size of the chest cavity. therefore the decrease in volume causes an increase in the internal air pressure. The internal air pressure is then higher then the environments pressure, resulting in the air moving out if the lungs.

When inhaling air, your diaphragm which is located below your rib cage, moves down allowing as much air to fill up in the lungs, and as you breathe out(exhale) your diaphragm moves up, allowing the air to exit your lungs. Your rib muscles help your lungs when expanding and helps your lungs relax while deflating. Your rib cage, which is used as a protective shield around your lungs, moves up as you inhale air, increasing the size of your chest cavity. All of those three parts allow you to breathe efficiently.

your lungs are in your chest cavity which is protected by your ribs, diaphragm and chest muscles.

As you inhale your rib cage rises, the diaphragm contracts and moves downward slightly. This happens in order to make the chest cavity bigger. This causes the internal air pressure of the cavity to be less than the air pressure in the environment. Air rushes into the lungs to equalize the pressure.

When you exhale, the rib cage lowers as the diaphragm rises. As this happens the size of the chest cavity deceases. This makes the internal air pressure in the cavity increase. The air will move out of your lungs because of the internal air pressure being higher than the environments air pressure.

Lungs are located within your chest cavity which is encased by your ribs, diaphragm and chest muscles. While inhaling, your rib cage rises up and your diaphragm moves down, therefore increasing the size of your chest cavity. Since the internal air pressure of the cavity is less than the air pressure of the environment, air quickly flows into your lungs, equalizing the pressure. When exhaling, your rib cage lowers and your diaphragm relaxes and moves up decreasing the size of your chest cavity. The decrease in the volume of the cavity causes an increase in the internal air pressure in the cavity. Since the internal air pressure is higher than the air pressure of the environment, air moves out of your lungs.

your chest muscles ribs and diaphragm work together to help you breathe efficiently.
your lungs are found in your chest cavity which its protected by your ribs diaphragm and chest muscles. when you inhale your ribs   and your diaphragm contract to allow you to suck air into your lungs when this happens it increases the volume in your chest cavity and lowers the internal air pressure and as you exhale your ribs and diaphragm relax allowing your lungs to let all the air out as this happens every part of your chest relaxes and it decreases the size of your chest. ravynn

breathing is a process of inhaling and exhaling air to provide oxygen for your body, but how does it work?

your lungs are enclosed within your chest cavity, that are surrounded by your ribs, chest muscles and diaphragm. as you inhale your rib cage will begin to rise and your diaphragm will contract. this allows you to increase the size of your chest cavity, filling up your lungs with air. your cavity will decrease in air pressure do to the increase of volume.

as you exhale air your rib cage will begin to lower as your diaphragm moves up. this decreases the size of your chest cavity. there is then an increase in air pressure due to the decrease in volume.

your lungs are in your chest cavity, inside your ribs surrounded by your chest muscles and your diaphragm. When you breathe in your rib cage rises and your diaphragm starts to contract to make your chest cavity bigger lowering the air pressure allowing you to take in more air and needed oxygen, once you inhale the pressure is equalized, as you exhale your rib cage lowers and your diaphragm relaxes and moves back up decreasing the size of your chest cavity

Our lungs are found in our chest cavity, they are protected by the rib cage and diaphragm. When we inhale we use our chest muscles to expand our chest cavity rises and lungs letting in more air. When we exhale it is the opposite and our chest cavity lowers and our lungs deflate pushing the air out of our lungs. The reason we can do this efficiently is because of our chest muscles because they allow us to control the way our lungs move.

Your lungs which are found in chest cavity are encircled by the ribs, chest muscles and the diagraphragm. When you breath in your rib cage rises and you're diagraphragm contracts and moves downward which increases the size of your chest cavity. While when you exhale your rib cage lowers and your diaphragm relaxes and moves upwards which decreases the size of your chest cavity.

The lungs are found inside the chest cavity, and within the rib cage. it is also surrounded by chest muscles, and is situated above the diaphragm. When you inhale, the diaphragm contracts, causing the lungs to inflate due to the lack of internal air pressure. the chest cavity expands and the rib cage rises to accommodate for the space taken up by the lungs.   In exhalation, the diaphragm relaxes and the rib cage lowers, decreasing the size of the chest cavity, and the lungs release air because the internal air pressure is now higher than it is outside of the body.

Your chest muscles, ribs and diaphragm help us breath efficiently because when you inhale your rib cage rises and diaphragm contracts which increases the size of your chest cavity. The increase of the volume of the chest cavity lowers the internal air pressure and because that pressure is lower than the pressure of the environment, air flows into the lungs to equalize the pressure. The opposite happens when you exhale, rib cage lowers, diaphragm relaxes and the size of the chest cavity decreases. This allows the volume of the cavity to decrease making the air pressure higher then the outside environment which then makes the air move out of your lungs.

When you inhale, your rib cage rises and your diaphragm contracts moving downwards, the size of your chest cavity increases. When you inhale your chest cavity expands as the rib cage rises then the diaphragm contracts it moves downwards. There is an increase in the volume of the cavity which causes a decrease in the internal air pressure in the cavity, the rib cage lowers and the diaphragm relaxes which will decrease the size of your chest cavity. When you inhale through your mouth your rib cage rises which your diaphragm goes down/inhalation, when you exhale air goes up lowering your rib cage and the air exhales relaxing the diaphragm relaxes and moves upward, decreasing the size of your chest cavity.

The rib cage begins to rise as the diaphragm moves down and contracts. This is done to increase the size of the chest cavity. Air rushes into your lungs so that the internal pressure of the cavity and the air pressure is equal.

When one exhales, the rib cage happens to lower as the diaphragm moves up and relaxes. Because of this, the size of your chest cavity decreases. This causes the internal air pressure in the cavity to increase. The air will move out of your lungs due to the internal air pressure being higher than the environment's air pressure. -Ali

Your lungs are closed like a cage surrounded by your ribs,chest muscles and diaphragm.When you breathe in your rib cage moves up and the diaphragm moves down to make the chest cavity bigger.The air inside your body is less than the air outside pressure wise so air goes to your lungs to make the air inside and outside the same level of pressure

When exhaling your body doing the opposite your rib cage lowers and your diaphragm moves upwards, decreasing the size of your chest cavity.The lowering of the volume of the cavity causes an increase in internal air pressure in the cavity.So since the air inside your body is different pressure from the air outside air leaves your lungs

Your lungs are located in your chest cavity, surrounded by your ribs, chest muscles, and diaphragm. By inhaling, the rib cage rises, the diaphragm contracts and descends, and this increases the size of your chest cavity. This causes a decrease in internal air pressure in the cavity. Then, since the internal air pressure is less than the air pressure of the environment, the air rushes toward your lungs to balance the pressure.
By exhaling, the opposite happens- the rib cage lowers, the diaphragm relaxes/moves up. These actions decrease the size of the chest cavity. Because the internal air is at a higher pressure than the environment, air moves out of the lungs.
These actions, repetitively, give us the action of breathing, which allows us to survive.

How chest muscles, ribs, and the diaphragm work together to help you breath efficiently:

Lungs are found in the chest cavity, which is protected and enclosed by your ribs, chest muscles and diaphragm.

As you inhale your rib cage rises and your diaphragm contracts and moves slightly downward. This occurs in order to increase the size of your chest cavity. This causes the internal air pressure of the cavity to be less than the air pressure in the environment, therefore air rushes into your lungs to equalize the pressure.

When you exhale, your rib cage lowers and your diaphragm relaxes and moves upwards. Therefore decreasing the size of your chest cavity. The decrease of the cavity causes an increase in internal air pressure. Since the internal air pressure is higher in the cavity than the air pressure of the environment, air then moves out of your lungs to help balance and equalize the pressure.
