Respiratory System Function


Exchange of oxygen and carbon dioxide
between the atmosphere and body cells.
The process is called respiration.

External respiration (breathing): Oxygen passes
from lungs to blood (capillaries) and carbon
dioxide passes from capillaries back into lungs to
be expelled.
 Internal respiration: The body cells take on oxygen
from the blood and give back carbon dioxide,
which is transported back to the lungs.

5-5
Organs of the Respiratory System


nose: lined with mucous membrane and fine
hairs; acts as a filter to moisten and warm the
entering air
pharynx (throat): serves as a food and air
passageway

adenoid: lymphoid tissue located behind the
nasal cavity
 tonsils: lymphoid tissue located behind the mouth

Organs of the
Respiratory System (cont’d.)



larynx (voice box): location of the vocal
cords
epiglottis: flap of cartilage that automatically
covers the opening of the larynx during
swallowing and keeps food from entering the
larynx
trachea: passageway for air to the bronchi

5-7
Organs of the
Respiratory System (cont’d.)

bronchus: one of two branches from the
trachea, which conducts air into the lungs,
where it divides and subdivides (referred to
as a bronchial tree).


bronchioles: smallest subdivision of the bronchial
tree
alveoli: air sacs at the end of the bronchioles;
oxygen and carbon dioxide are exchanged
through alveolar walls and capillaries

5-8
Organs of the
Respiratory System (cont’d.)

lungs: 2 sponge-like organs in the thoracic
cavity (right lung has 3 lobes; left lung has 2
lobes)



pleura: serous membrane covering each lung and
lining the thoracic cavity
diaphragm: muscular partition that separates
the thoracic cavity from the abdominal cavity;
aids in breathing
mediastinum: space between the lungs

Read Medical Terms In Use
A 24-year-old man visited the emergency department
because of dyspnea, hyperpnea, paroxysms of
cough (kawf), and the presence of thick, tenacious
mucus. He had a history of asthma since the age of
12 years. A chest radiograph was negative for
pneumonia. Arterial blood gases showed
hypoxemia but no hypercapnia. Pulmonary
function tests disclosed bronchoconstriction, which
was corrected by a bronchodilator. A nebulizer was
prescribed for treatment. The asthma attack was
probably precipitated by an episode of bronchitis.
