The diaphragm contracts and a vacuum is created inside the thorax. The lungs expand to fill the space created, as reduced air pressure allows air to expand the lungs. The intercostals' muscle contract and lift the ribcage further increasing the thoracic space.

∙ 11y agoWhen you inspire (breath in), the air moves into the lungs. This is because an area of low pressure is created inside the chest cavity when the diaphragm contracts. Contraction of the diaphragm allows more space to be made inside of the ribcage. This causes an area of low pressure to develop. Since air moves down the concentration gradient (from high to low), air moves into the lungs. Since the lungs aren't muscle, they'll expand as far as the chest cavity will allow. Relaxation of the diaphragm pushes on the lungs and air is pushed out.

What do you call air moving through the respiratory tract during inspiration?
Nose, larynx, trachea, bronchi, bronchioles.
You put more efforts when you exhale air or when you inhale the air?
During normal breathing at rest, inspiration is an active process while expiration is passive. So under normal conditions, you put more energy into inspiration than expiration.
What happens to the abdomen during inspiration?
The diaphragm contracts and so your abdomen comes out during inspiration.
What is the relationship between the Eustachian tube and the pharynx?
When food is swallowed, the epiglottis covers the trachea. During inspiration, the epiglottis allows air to pass into the trachea.

How do the lungs take in and breathe out?
During inspiration the ribs move upwards and outwards and the diaphragm contracts ,thus,increasing the volume of the thoracic cavity.this leads to a decrease in pressure inside the lung.therefore the air from outside rushes in . During expiration the ribs move inwards and downwards and the diaphragm relaxes thus,creating low pressure .this leads to the expulsion of air from our body.
How does the air move during day time and during night time?
the cool air pushes the warm air
How does pneumothorax affect lung pressure and aleveolar pressure when inspiratory muscles contract?
A pneumothorax is air in the plural cavity. When a person takes a breath the lung cannot expand. This expatiation normal lowers the pressure in the lungs allowing air to move into the longs, without expatiation during inspiration the pressure does not change and air will not move in.

During normal breathing at rest, inspiration is an active process while expiration is passive. So under normal conditions, you put more energy into inspiration than expiration.
What are inspiration and expiration in relationship to breathing?
inspiration is when air is breathed in through the mouth or nose which then goes into the air passage and into the alvioli which transfers the oxygen around the circulatory system to be used by the working muscles.expiration is breathing out.impure air containing CO2 is let out during tat process
How does the expansion of the chest wall expand the lungs during inspiration?
the air goes up to the chest cavity. Hope this helps you!
What happens to the abdomen during inspiration?
The diaphragm contracts and so your abdomen comes out during inspiration.
How does the air move during night time and day time?
the cool air pushes the warm air
Period of breathing when air leaves the lungs?
Inspiration.
What is the intake of air called?
inspiration
How does the air move during day time?
it changes when the axis turn
