The document discusses the structure and function of the human respiratory system. It describes the major parts as the airway, lungs, and respiratory muscles. The airway includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles. The trachea is a tube that connects the larynx to the lungs. It branches within the lungs into the right and left primary bronchi. The bronchi further divide into smaller secondary and tertiary bronchi, and bronchioles which do not participate in gas exchange.

3. respiratory system
• 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.
•

4. • Lower respiratory tract: Composed of the
trachea, the lungs, and all segments of the
bronchial tree (including the alveoli), the
organs of the lower respiratory tract are
located inside the chest cavity. Trachea:
Located just below the larynx, the trachea is
the main airway to the lungs.
What are the different organs that
make up the respiratory system?

5. What is the function of the respiratory
system?
• The function of the human respiratory
system is to transport air into the lungs and to
facilitate the diffusion of Oxygen into the
blood stream. Its also receives waste Carbon
Dioxide from the blood and exhales it.

6. structure and function of the
respiratory system
• There are 3 major parts of the respiratory
system: the airway, the lungs, and the
muscles of respiration. The airway, which
includes the nose,
mouth, pharynx, larynx, trachea, bronchi, and
bronchioles, carries air between the lungs and
the body's exterior.

9. Diseases of the respiratory system
• Featured in Respiratory System Diseases
• asphyxia.
• (TB)
• pneumonia.
• asthma.
• sleep apnea.
• chronic obstructive pulmonary disease (COPD)
• lung cancer.
• influenza.

10. MOUTH & NOSE
• The lungs work to pass oxygen into the body,
whilst removing carbon dioxide from the body.
The muscles of respiration, such as the
diaphragm, work in unison to pump air into
and out of the lungs whilst breathing.
The nose is the primary opening for
the respiratory system, made of bone,
muscle, and cartilage.

12. Trachea
• Trachea (Windpipe) The trachea (or windpipe)
is a wide, hollow tube that connects the larynx
(or voice box) to the bronchi of the lungs. It is
an integral part of the body's airway and has
the vital function of providing air flow to and
from the lungs for respiration.
• Shape-- cup-shaped

13. Structure
• he human trachea has an inner diameter of about 25
millimetres (1 in) and a length of about 10 to 16
centimetres (4 to 6 in). It commences at the lower
border of the larynx, level with the sixth cervical
vertebra. Inside the trachea at the level of the
fifth thoracic vertebra(T5) there is a cartilaginous ridge
known as the carina of trachea which runs across from
the front to the back of the trachea and marks the
point of bifurcation into the right and left
primary bronchi. The carina is opposite the sternal
angle and can be positioned up to two vertebrae lower
or higher, depending on breathing.

16. What is the role of the trachea?
• The trachea, or windpipe, is a 5-inch long tube
made of C-shaped hyaline cartilage rings lined
with pseudostratified ciliated columnar
epithelium. The trachea connects the larynx
to the bronchi and allows air to pass through
the neck and into the thorax.

17. Is the trachea considered an organ?
• The trachea is an important structure within
your respiratory system, which is
the organ system that delivers oxygen to your
bloodstream. The trachea is a rigid tube that
conducts air from your larynx to your bronchi.

18. What is the respiratory system made
up of?
• There are 3 major parts of the respiratory
system: the airway, the lungs, and the muscles
of respiration. The airway, which includes the
nose, mouth, pharynx, larynx, trachea,
bronchi, and bronchioles, carries air between
the lungs and the body's exterior. The lungs...

19. bronchi
• The bronchi, singularly known as a bronchus,
are extensions of the windpipe that shuttle air
to and from the lungs. Think of them as
highways for gas exchange, with oxygen going
to the lungs and carbon dioxide leaving the
lungs through them. They are part of the
conducting zone of the respiratory system.

21. • A bronchus, also known as
a main or primary bronchus, is an airway in
the respiratory tract that conducts air into
the lungs. There is a right bronchus and a left
bronchus and these bronchi branch into
smaller secondary and tertiary bronchi which
branch into smaller tubes, known
as bronchioles.[1] No gas exchange takes place
in the bronchi.

22. Why is the right bronchus shorter and
wider than the left?
• The right main bronchus, about 2.5 cm in
length, is shorter, wider, and more nearly
vertical than the left. Because it is in almost a
direct line with the trachea, foreign objects
traversing the trachea are more likely to enter
the right main bronchus.

23. What is the structure and function of
the bronchi?
• Structure. The structure of the larger bronchi
is identical to that of the trachea. On the
smaller bronchi the C-shaped cartilage
rings are gradually replaced by irregular
plaques of cartilage. Bronchioles have
no cartilage at all.
