What causes the air pressure in your lungs to decrease and make you inhale?

When you inhale, oxygen fills your lungs. Next the oxygen diffuses out of your lungs into your bloodstream. The diffusion of oxygen from the lungs causes less pressure in your lungs signaling your brain that you need to inhale.


What element makes up the majority of the air we inhale?

are lungs and oxogent


Why do your lungs inhale and exhale?

I believe that the pressure from the diaphragm causes our lungs inflate, thus we inhale and when the diaphragm deflates, it makes us exhale.--------------------------------------------------------------------- As your diaphragm or intercoastal muscles contract the size of the lungs increases. This creates a pressure difference between your lungs and the surrounding atmosphere. By increasing the size of the lungs you create a low pressure environment in the lungs by expanding the same amount of gas to a larger area. this pressure difference doesn't have to be much 1mmhg is more then enough, the main thing is just that you need a difference in preasure. Air flows from high preasure to low preasure, so by decreasing the preasure in the lungs air flows into the lungs. as you breath out you make the lungs smaller by relaxing the muscles and diaphragm, making the volume in the lungs decrease, thus increasing the preasure and moving the air from inside the lungs out to the surrounding atmosphere.


How do lungs look after cancer?

Lungs does not look after the cancer because the lungs do more than 500 jobs in your body,cancer makes you die and makes people cut their hair off


Beside your lungs what other part of the body makes way to let the lungs inhale?

The diapragm is most important to the respiratory process. Your diaphragm pulls down when you inhale, opening your lungs up and letting air in. Your trachea is what brings athe air from your nose to your lungs. Nose, pharynx, larynx, trachea, bronchi, lungs, and diapragm are all involved.


Why the rib moves up when you inhale?

Actually the ribs are moving outward and expanding as the lungs fill with air. The expansion of the ribs makes room for more air to enter the lungs.


What makes the lungs operate?

its all by pressure, our diaphragm (muscle in our chest) contracts and relaxes causing high and low pressure and makes the lungs expand etc, think of a balloon in a jar and you can controll the pressure on the outside of the balloon, it will inflate and deflte


What would happen to heart rate if some stimulus caused blood pressure to decrease?

gettin g shanked makes yo heart slow down and blood pressure decrease


What is the large muscle that helps breathing?

The diaphragm is the primary muscle involved with breathing. When you want to take a breath in (inhale) you contract your diaphragm. This makes the thoracic cavity larger, decreasing the pressure in the thoracic cavity and generating a vacuum. Air is drawn into the lungs because of the creation of this intra-thoracic vacuum. When you relax your diaphragm the elasticity of your lungs will force air back out (exhalation).


What transports air to the lungs?

AnswerAir is actually forced into the lungs by atmospheric pressure. But here's the rest of the story. The diaphragm, a muscle below the lungs, contracts and actually makes the space in which the lungs are located, the thorax, get bigger. When this space gets bigger, the pressure inside it decreases. There is now a difference in pressure between the lung cavity and the outside air with the outside air having more pressure. Air goes from where the pressure is higher to where it is lower, and so it goes into the lungs. That's called inspiration or inhaling. When the diaphragm relaxes, the thorax gets smaller and the pressure increases in the lungs and air is forced out. Click the link for more information.


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.
