DISCUSSION TEXT
.
Respiration is an event when the body lacks oxygen (O2) and

what is outside the body is inhaled (inspiration) through the
respiratory organs. In certain circumstances the body has an
excess of carbon dioxide (CO2), so the body tries to exhale this
excess by exhaling (expiration) resulting in a balance between
O2 and CO2 in the body. The respiratory system's role is to
circulate air to the inner surface of the lungs. Air enters and
stays in the respiratory system and enters the muscular
respiratory system.
Respiratory system function
The five basic functions of the respiratory system are:

1. where gas exchange occurs from the atmosphere with blood circulation
2. moving air to and from the surface of the lungs
3. Protect and protect the mucosa from dehydration, temperature changes, or
environmental variations, as well as defend other mucosal surfaces from
bacterial invasion promoter
4. produce sounds or voices for speaking, singing, and other verbal
communication activities
5. olfactory sensations to be sent to the central nervous system from the
epithelium providing the olfactory nerves in the superior part of the nasal cavity:
indirectly, pulmonary capillaries help regulate blood volume and pressure.
Anatomy of the respiratory
system
The anatomy of the respiratory tract

consists of the upper respiratory tract
(nasal cavity, nostril, and pharynx),
lower respiratory tract (larynx,
trachea, bronchi, and alveoli),
pulmonary circulation , lungs (3 lobes
on the right and 2 on the left), pleural
cavity, and diagpragm
1. Nasal Cavity
The nose consists of two nostrils which are the
entrances to the nasal cavity. The mucosa
filters, warms, and moistens the air that enters
the nose. The vestibule is part of the nasal
cavity which is hairy and functions to filter
large foreign particles so they do not enter the
lower respiratory tract
2.pharynx
The pharynx (throat) is a muscular tube
that starts at the base of the skull and ends
up junction with the esophagus and
cricheid cartilage hatas, Pharynx consists
of three parts which are named based on
their location, namely the nasopharynx
(behind the nose), arofaring (behind the
nose) (mouth), and laryngopharynx
(behind the larynx).
3.Larynx
The larynx (throat) is located between the pharynx and the
trachea. Based on the location of the cervical vertebrae, the
larynx is at the 4th or 5th vertebra and ends at the 6th cervical
vertebrae. The larynx is composed of 9 cartilages which are
held together by ligaments and skeletal muscles in the hindgut
above and the trakches below. The largest cartilage is the
thyroid cartilage, and in front of it is the sabeutaneal lump
known as the Adam's apple that is visible in men.
4.Trachea
The trachea is a tube with a diameter of 2.5

cm and a length of 11 cm (can be seen in
Figure 1-5). The trachea is located after the
larynx and extends downward equivalent to
the 5th thoracic vertebra. The lower end of
the trachea branches into two bronchi
(bronchi). Right and left. The branching of the
right and left bronchi is known as the carina
(carina). The trachea is composed of 16-20 C-
shaped haline cartilages that attach to the
walls of the trachea and serve to protect the
airways.
5.Bronhci
The bronchi are one of the respiratory

organs in humans in the form of a pair
of bronchial branches, one of the
branches leading to the lungs and the
other branch leading to the left lung.
This branching section is called a
bifurkase. The bronchi are similar in
structure to the trachea and are lined by
the same cell types.
.
6.Bronchioles

Bronchioles are branches of the bronchi,

the walls in the bronchioles are thinner
besides that the channels are also smaller
when compared to the bronchioles. In the
bronchioles the smaller the channels, the
less cartilage and finally only the fibrous
walls with a layer of cilia remain.

7.Alveoli
Alveoli become the final channel of the

respiratory apparatus in humans in the form
of air bubbles. The walls are thin, with moist
conditions and attached to each other with
blood capillaries. In the alveoli there is a
single layer of flat epithelial cells and it is in
this place that air comes into almost direct
contact with blood.
8.Diaghragm
The diaphragm is a muscle that

is at the base of the internal
skeleton between the chest cavity
and the abdominal cavity which
plays a role in the breathing
process.
CONCLUSION
Respiration is an event when the body lacks oxygen

(O2) and what is outside the body is inhaled
(inspiration) through the respiratory organs. In certain
circumstances the body has an excess of carbon dioxide
(CO2), so the body tries to expel this excess by
bandaging the breath (expiration) so that there is a
balance between O2 and CO2 in the body, which
consists of various organs starting from the nose,
larynx, pharynx, trachea, bronchi, bronchioles, alveoli,
diaphragm and lungs.
