1) Pressure changes caused by 2) your chest muscles PLUS your rib cage cause the volume of your thoracic cavity to change.
The force that causes you to move upward when you jump into the air is the normal force exerted by the ground on your feet. This force opposes the force of gravity acting on your body, allowing you to overcome gravity and move upward.
Heat causes air to warm and expand, which lowers its density compared to cooler air. This reduction in density creates a pressure difference between the warm air and the cooler surrounding air, leading to the movement of air in the form of convection currents.
Wind is what causes the movement of water on the surface. The wind creates friction against the surface of the water, causing it to move in the same direction.
Warm air molecules move by gaining energy and increasing their speed, leading to expansion and becoming less dense than surrounding cooler air. This causes the warm air to rise and mix with the cooler air in a process called convection.
Hot breath in humans is caused by the warm air expelled from the lungs during breathing. This air is heated by the body's internal temperature and can feel warm when exhaled.
the expansion and relaxation of your diaphram.
your diafram
breathing is the human action that causes the lungs to be filled with air.
I think you meant move air into the lungs. The muscle is the diaphragm.
Suction is the force that "draws" or pulls rather than "drive" air into the lungs.When the diaphragm muscle pulls down, and the ribs expand slightly, the lungs also expand which sucks air into them.(see related links below)
inhale:- the air pressure in the lungs decreases and air moves in. exhale:-air pressure in the lungs increases and air moves out.
The contraction of the diaphragm causes it to move down, increasing the volume of the thoracic cavity. This movement and volume change decrease the pressure in the lungs, and air rushes in.
This varies between different people, so a sporty persons lungs would have adapted to hold my air than a normal persons. Also a pro swimmer would have more air capacity in their lungs so they could hold it for longer.
what happens when you inhale is that air goes into your lungs and your lungs get bigger ...Actually, your diaphragm moves to expand the volume of your thoracic cavity, which pulls a partial vacuum on your lungs, causing them to expand FIRST...and THEN the partial vacuum created by your expanded lungs causes air to move into them. When you breath out, it causes the reverse to occur.
When your lungs move to bring in air and remove gases you are breathing.
There are no muscles in the lungs that help inhale or exhale, this is the job of the diaphragm.
Contraction of the diaphragm muscle causes it to move back up. When the diaphragm contracts, it flattens and moves downwards, increasing the volume in the thoracic cavity. This action creates negative pressure, sucking air into the lungs.
