UNIT 5: CHAPTER 23
THE RESPIRATORY SYSTEM
List the functions of the Respiratory System: Pg
...
The 2 broad aspects of
respiration are; ventilation and respiration
...
In addition to respiration, the respiratory system performs the following functions:

List the structures that compose the respiratory system:
There are several structures that make up the respiratory system:
1
...
Nasal cavity: is a cleaning, warming and humidifying chamber for inspired air
...
Pharynx: commonly called the throat, it serves as a common passageway for food
and air
...
Larynx: is usually called the voice box
...
5
...
It serves as an air cleaning tube to funnel
inspired air into each lung
...
Bronchi: are tubes that direct air into the lungs
...
Lungs: each lung consists of a maze of air tubes, and a complex network of air sacs
(called alveoli and capillaries)
...
***See figure 23
...
The largest part of our noses is
made up of hyaline cartilage plates
...
Nasal cavity
Is the open chamber inside the nose where air enters the respiratory
system
...
Nasal Septum
Nasal cavity
5 functions of
the nasal
cavity
The floor of the nasal cavity, which separates it from the oral cavity in
the mouth, is called the hard palate
...
The anterior nasal septum is made up of cartilage while the posterior
part consists of the vomer bone and part of the ethmoid bone
...
It is a critical component of respiration and has 5 functions

Describe the structure of the lungs, including blood supply
...
o The lungs are the primary organs of respiration
...
o The portion of the lungs in contact with the diaphragm is the base
...
The right lung is also slightly larger than the left
...
This is where
structures such as bronchus, blood vessels, nerves and lymphatic vessels enter and
exit the lung
...
o Blood supply: Blood that has passed through the lungs and picked up Oxygen is
called oxygenated blood, and blood that has passed through the tissues and
released some of its oxygen is called deoxygenated blood
...
o The first (major) route: Deoxygenated blood flows through pulmonary arteries then
capillaries (in the alveoli) where it is oxygenated and returns to the heart through
pulmonary veins
...
Pg 854
o Once oxygen and carbon dioxide enter the blood, they interact with components
that aid in their solubility and reduce the potentially dangerous impact CO2 could
have on blood pH
...
o Hemoglobin: is a complex protein made by immature red blood cells
...
o Type 1 & 2 are called embryonic and fetal hemoglobin: which are unique forms of
hemoglobin found in the red blood cells of embryos and fetuses only
...
It is this heme group that oxygen binds to, so one hemoglobin
can carry up to 4 oxygen molecules
...
This type is found in individuals
who have a disease called sickle-cell anemia
...
Approximately 98
...
o Transport of CO2: CO2 is a byproduct of the breakdown of glucose
...
The blood concentration of CO2 needs to be tightly
regulated because too much of it in the blood causes the blood to become acidic
...
Describe how blood pH,
Define Asthma and list the symptoms and treatment of this condition:
o Asthma is a condition of the lungs in which widespread narrowing of airways occurs,
caused by contraction of smooth muscle, edema of the mucosa and mucus in the
lumen of the bronchi and bronchioles
...
o Treatment: avoid the causing agent (asthma is sometimes brought on by exercise,
allergen, chemicals), taking of medication and using bronchodilators
