The primary function of the respiratory system is to supply
oxygen to the blood system in order for the blood to
deliver oxygen to all parts of the body. The respiratory
system does this through breathing. When we breathe, we I
inhale oxygen and exhale carbon dioxide. This exchange of
gases is the respiratory system's means of getting oxygen
to the blood.
Respiration is achieved through the mouth, nose, trachea,
lungs, and diaphragm. Oxygen enters the respiratory system
through the mouth and the nose. The oxygen then passes
through the larynx (where speech sounds are produced) and
the trachea which is a tube that enters the chest cavity.
In the chest cavity, the trachea splits into two smaller
tubes called the bronchi. Each bronchus then divides again
forming the bronchial tubes. The bronchial tubes lead
directly into the lungs where they divide into many smaller
tubes which connect to tiny sacs called alveoli. The
average adult's lungs contain about 600 million of these
spongy, air-filled sacs that are surrounded by capillaries.
The inhaled oxygen passes into the alveoli and then
diffuses through the capillaries into the arterial blood.
Meanwhile, the waste-rich blood from the veins releases its
carbon dioxide into the alveoli. The carbon dioxide follows
the same path out of the lungs when you exhale.
The diaphragm's job is to help pump the carbon dioxide out
of the lungs and pull the oxygen into the lungs. The
diaphragm is a sheet of muscles that lies across the bottom
of the chest cavity. As the diaphragm contracts and
relaxes, breathing takes place. When the diaphragm
contracts, oxygen is pulled into the lungs. When the
diaphragm relaxes, carbon dioxide is pumped out of the
lungs.
