primary function of the respiratory system
Is to provide oxygen for the body and remove gaseous waste carbon dioxide
secondary function of the respiratory system
Maintaining the acid, base, balance, producing speech, facilitating, smell, and maintaining the bodies heat and water balances
external respiration
Moves oxygen from the air into the blood
External respiration is the process involved in breathing, the ventilation of the lungs, and the exchange of oxygen (O2) and carbon dioxide and carbon dioxide(CO2) between the air in the lungs and the blood
internal
Moves oxygen from the blood to the tissues
Internal, this change of oxygen, internal, this change of oxygen, (O2) and carbon dioxide (CO2) is called cellular respiration
Respiratory system
cooperates with the circulatory system, to provide oxygen for body cells, and to expel waste carbon dioxide through breathing.
In/spir(o)/ation
inspiration
In(into) + spitro)( to breathe) + action(process)
Means drawing of air into the lungs (inhalation)
The process of breathing in
A.k.a. in/halation
inhalation
expiration a.k.a. exhalation
Expelling air from the lungs (breathing out) by active breathing out or letting out one’s breath
Pulmonologist
Is a physician specializing in evaluating and treating lung disorders
A physician who specializes in lungs and respiratory disorders
Ventilation
Another term for breathing
Breathing/pulmonary ventilation
pulmon/ary
Pertains to the lungs
Conducting passages
Are known as the upper respiratory tract and the lower respiratory tract
upper respiratory tract
Nose, nasal cavity, nasopharynx, oropharynx, laryngopharynx, larynx
nose, nasal cavity, paranasal sinuses, pharynx, and larynx
lower respiratory tract
Trachea, bronchi, bronchioles, alveoli, and lung capillaries
Pleura
There are two types, and are separated by a lubricating fluid
Nasopharynx
Is the upper part of the pharynx
Is nearest to the nasal cavity
Larynx
Is the organ of the respiratory tract that is indicated in laryngitis
The glottis is the vocal apparatus of the
The organs of respiration
Air first enters the body through the nose and passes through the nasal cavity 1. or it enters through the mouth and passes through the oral cavity 2. The air reaches the pharynx 3. And passes through the larynx 4. And the trachea 5. The trachea divides into a left and right bronchus 6. Each Bronchus divides into smaller tubes called bronchioles 7. At the end of each bronchiole are clusters of air sacs called alveoli 8. Where oxygen is exchanged for waste carbon dioxide.
diaphragm
Normal quiet, breathing is accomplished almost entirely by movement of the
epiglottis
Covers the Larynx during swallowing to prevent food from entering the larynx and trachea
Parts of the lung starting from the top
Apex - the very top of the lung
Trachea - in between the two longs
Left primary bronchus - splits off from the trachea
Right pulmonary artery
right pulmonary veins
Coastal surface of the lung
Base of lung
Two types of pleura
Visceral pleura - inner layer of the lung
Parietal pleura - outer layer of the lung
Clusters of alveoli
are at the end of the bronchioles and reassemble a bunch of grapes
About 300 million alveoli
in a pair of healthy adult lungs, providing a large surface for exchange of carbon dioxide and oxygen,
Which structure is nearest the larynx? which structure is nearest the Lorax?
Trachea
