The human respiratory system takes in oxygen and expels carbon dioxide using the lungs and other organs. The lungs carry out the exchange of gases as we breathe. Red blood cells collect oxygen from the lungs and distribute it throughout the body. During inhalation, the diaphragm and intercostal muscles contract and expand the rib cage and lungs, increasing their volume and allowing more air to enter. Exhalation is the movement of air out of the bronchial tubes and lungs to the external environment during breathing.

2. The human respiratory system is a
series of organs responsible for
taking in oxygen and expelling
carbon dioxide. The primary
organs of the respiratory system
are lungs, which carry out this
exchange of gases as we breathe.
Red blood cells collect the oxygen
from the lungs and carry it to the
parts of the body where it is
needed.

3. *On inhalation the diaphragm muscle contracts and
intercostal muscles dilate. The diaphragm
descends from his position and intercostal muscles
as a result of the position adopted, raise the ribs.
When this happens, the volume of the rib cage
increases together with the volume of the lungs,
and has more space.

current out of the organism. In humans
it is the movement of air out of the
bronchial tubes, through the airways,
to the external environment during
breathing.

Bronchus - Bronquios
Alveolus - Alvéolos
Trachea- Tráquea
Bronciole - Bronquiolos
Diaphagram - Diafragma

*Bronchi are also called the
segmental bronchi. They
branch out from the secondary
bronchi, which descend from
the mainstream bronchi.

Part of the respiratory
system, these tiny
alveoli have a key role
in the movement of
oxygen and carbon
dioxide.

*The trachea is a tube of
wide, hollow that
connects the larynx to
the bronchi of the lungs.

One of the successively
smaller channels into

bronchi divide within
the bronchus
pulmonary segments.

*The diaphragm in the
respiratory system is the
dome-shaped sheet of
muscle that separates the
chest from the abdomen.
