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.

What is the air pressure inside a papper bag?
The air pressure is the same, inside or outside the paper bag.
Why does a syringe plunger go back in if you pull it out?
When the plunger is pulled, the volume inside increases. This reduces the pressure inside, and the air pressure outside forces liquid in, in an effort to make the pressure inside and outside the syringe equal again.
When the water level is higher inside than outside the flask is the gas pressure in the flask higher than lower than or the same as the atmospheric pressure?
When the water level is higher inside than outside the flask, the gas pressure in the flask is lower than the atmospheric pressure. This is because the weight of the column of water inside the flask creates an additional pressure on the gas inside, reducing its pressure relative to the atmospheric pressure outside.
Is it true or false that changes outside the body may bring about changes inside the body?
no
What is a specialized nerve endings in sensory nuerons that detect changes inside and outside the body called?
Specialized nerve endings in sensory neurons that detect changes inside and outside the body are called sensory receptors. These receptors can respond to various stimuli such as temperature, pressure, and chemicals, sending signals to the brain for interpretation.
Why do ears pop?
Ears pop due to changes in air pressure. When the pressure inside the ear is different from the pressure outside, the eardrum flexes to equalize the pressure, causing the popping sensation.
Why does toilet water move when it is windy?
When it is windy, the air pressure outside the toilet bowl changes, causing the water level inside the bowl to rise or fall. This movement of air pressure creates a difference in pressure between the inside and outside of the bowl, leading to the water moving.
Why doesnt air pressure crush an empty soda can sitting on a table in your house?
Air pressure pushes equally on all sides of the can, so the pressure from the outside and inside of the can is balanced, preventing it from being crushed. Without any changes in pressure or force acting on the can, it remains in its original shape.
What is the normal pressure inside or outside the house?
Inside pressure is warm and outside is cold. But any where outside my house there is no problem. Urine becomes normal and no problem
The air pressure inside the can compare to the air pressure outside the can equal lower or higher?
There is no difference of the average local air pressure inside or outside of the headphone.
What is the difference between the pressure inside and outside a tornado funnel?
The pressure inside a tornado funnel is lower than the pressure outside. This pressure difference is a key factor in the formation and strength of tornadoes, as the low pressure inside the funnel contributes to the destructive force of the winds associated with tornadoes.
Why does the can crush when placed in cold water?
When a can is placed in cold water, the air inside the can cools down and contracts, creating a lower pressure inside the can compared to the outside. The higher pressure outside the can then crushes the can as it tries to equalize the pressure inside and outside.
What is the freon pressure for an air conditioner?
It changes based on vehicle, outside temp, and desired inside temp. Pressuse depends on ambient temperature, the higher the temp, the greater the pressure
Why does a sealed empty tin can collapse when the air inside the can is pumped out?
When the air inside the can is pumped out, there is a decrease in pressure inside the can. The outside air pressure then pushes on the sides of the can, causing it to collapse. This happens because the higher pressure outside the can is not balanced by the lower pressure inside the can.
Why doesn't air pressure crush an empty soft drink can as you go down a mountain?
because the pressure is the same on the outside and inside of can making the can staying the same and not being crushed
What is the air pressure inside a papper bag?
The air pressure is the same, inside or outside the paper bag.
Why do your ears hurt during take off and landing?
The pressure outside of your eardrum in the plane changes as the plane goes up or comes down - this causes pain because the pressure behind your eardrum is either higher or lower than the pressure inside the plane.
