When the air pressure in the lungs is greater than the air pressure outside the body you?
at higher altitudes the pressure of air is greater in our lungs as compare to the air pressure outside the body
Is air pressure more or less than outside the body when you inhale?
less
What involves changes in air pressure inside and outside your body?
Breathing involves changes in air pressure inside and outside your body. When you inhale, your chest expands because muscles between your ribs push the ribs apart to make a bigger space. Also, a sheet of muscle in the lower chest, called diaphragm, moves downward to make a bigger space.
How can your bodies keep from being crushed by air pressure?
Your bodies pressure inside your body can change itself tone equal to outside pressure
What is the air pressure inside a papper bag?
The air pressure is the same, inside or outside the paper bag.
When the air pressure in the lungs is greater than the air pressure outside the body you?
at higher altitudes the pressure of air is greater in our lungs as compare to the air pressure outside the body
Why Given that the air pressure outside your body is so great why aren't you crushed?
Pressure inside your body balances the air pressure outside your body.
What happens if the air pressure in the throat and outside is less than the air pressure in your middle ear when you swallow?
if the aie pressure in the throat and outside the body is less than the air pressure in your middle ear when you swallow the air pressure in your middle ear reaches the same pressure as the air in your throat and outside , and the eardrum moves quickly back-or'pops' into place
Is air pressure more or less than outside the body when you inhale?
less
What is the total pressure a lung exerts while breathing out?
During exhaling, air out of lungs, diaphragm is pushed upward and hence partial pressure in the ribs increases and the pressure outside the body is little less so air goes out of the body. During inhalation exact opposite of exhalation occurs Total pressure = partial pressure outside our body + partial pressure inside our body
How does air moves into and out of the lungs?
As the diaphragm contracts or retracts, the interior pressure of the lungs changes. As this pressure change occurs, the air pressure outside of the body remains unchanged. The resulting lack of pressure equality forces the air in or out of the lungs to maintain an equilibrium in the body pressure.
How does varying air pressure cause wind?
Wind, or breezes are simply the movement of a large amount of air from an area of high air pressure into an area of low air pressure. An Example of this happening on a small scale . . . blow air into your mouth with your nose and lips sealed. Your cheeks will push out. This results in high air pressure in your mouth - higher than the air outside your body. So open your lips a little, and the air under higher pressure will move out of your mouth into the lower pressure air outside your body.
Does the pressure inside your body balance the air pressure outside your body?
Somewhat. If you were to ride in an airplane without being in a pressurized cabin you might die because of drastically low air pressure. We are only built to live on land, but we are also built to withstand change in air pressure when walking a hill or climbing a mountain. The pressure also changes with weather and climate change. So again, our body balances the air pressure outside up to a certain extent.
What is the pressure of air outside of the body?
Atmospheric air pressure is about 100kPa but there is no net pressure on your skin because pressures inside and outside your body are equal In more common terminology, average ambient air pressure at sea level is 14.7lbs per square inch.
What involves changes in air pressure inside and outside your body?
Breathing involves changes in air pressure inside and outside your body. When you inhale, your chest expands because muscles between your ribs push the ribs apart to make a bigger space. Also, a sheet of muscle in the lower chest, called diaphragm, moves downward to make a bigger space.
As you ehxale the bronchioles in the lungs release most of their air?
The air pressure changes inside and outside the body, breathing takes place.In normal conditions,air moves from high pressure area to low pressure are.
When you exhale but dn't delibirately inhale why does air still flow into your lungs?
Because air diffuses from high pressure to low pressure, when we breath we aren't really "sucking" air in, our diaphragm lowers and our ribcage extends allowing our lungs to "expand" air then diffuses from the outside of the body into our lungs, when the diaphragm contracts it creates a higher pressure in the lungs compared to the outside, so air then diffuses from the lungs and out of the body.
