anatomy of the respiratory tract;
Larynx
Trachea
Sinuses
Nasal cavity
Nose
differences between the right and left lung and right and left primary bronchi;
right lung
The right lung has three lobes
Left lung
The left lung has two lobes
left primary bronchi
The left main bronchus is smaller in caliber but longer than the right
right primary bronchi
The right main bronchus is wider and shorter
Left lung
The left lung is smaller
Major functions of the
respiratory system;
Internal Respiration Exchanges Gases Between the Bloodstream and Body Tissues
Air Vibrating the Vocal Cords Creates Sound
External Respiration Exchanges Gases Between the Lungs and the Bloodstream
Olfaction, or Smelling, Is a Chemical Sensation
inhalation and Exhalation Are Pulmonary Ventilation That’s Breathing
breathing mechanism;
The lungs add oxygen to the blood and remove carbon dioxide in a process called gas exchange.
A healthy lifestyle can help prevent lung injury and disease.
Carbon dioxide is a waste gas produced by the cells of the body.
The lungs bring oxygen into the body when breathing in and send carbon dioxide out of the body when breathing out.
The process of breathing out is called exhalation
The process of breathing in is called inhalation
definitions of lung capacity terminology;
The expiratory reserve volume (ERV), about 1,200 mL
Residual volume (RV), about 1,200 mL
The inspiratory reserve volume (IRV), about 3,100 mL
The total lung capacity (TLC), about 6,000 mL,
The vital capacity (VC), about 4,800 mL
The inspiratory capacity (IC), about 3,600 mL
The functional residual capacity (FRC), about 2,400 mL
internal and
external respiration;
Breathing
intake of oxygen into the body and expulsion of carbon dioxide out of the body.
Gas exchange
Internal respiration occurs within cells of the body and involves all body cells, not just cells of the lungs.
External respiration describes respiration that occurs between the external environment and the cells of the body
Aerobic respiration which requires oxygen
Anaerobic respiration (also known as fermentation) which does not require oxygen
disorders of the respiratory system.
tuberculosis
Infectious, potentially serious bacterial disease, which mainly affects the lungs.
copd
A group of lung diseases that obstruct air circulation and make breathing difficult.
Pneumonia
Infection that inflames the air sacs of one or both lungs, which can fill with fluid.
Lung cancer
Cancer that begins in the lungs and usually manifests in smokers.
organs of the respiratory system and location
(upper and lower respiratory track)
trachea
(lower)he trachea begins just under the larynx
bronchi
(lower) located in the upper portion of the lungs,
larynx
(upper) found in the anterior neck
pharynx
(upper)It is found in vertebrates and invertebrates
alveoli
(lower)located in the alveolar sacs of the lungs in the pulmonary lobes
nose
(upper) The inner part of the nose is above the roof of the mouth
