The Respiratory System By: Philopater Migalli Period: 1
organs of the respiratory system and location
(upper and lower respiratory track)
Upper Respiratory Track: the organs of the upper respiratory tract are located outside the chest cavity
Larynx
Pharynx
Nose
Sinuses
Lower Respiratory Track: the organs of the lower respiratory tract are located inside the chest cavity
Lungs
Bronchi
Trachea
Diaphragm
differences between the right and left lung and right and left
primary bronchi
The left lung is smaller because of the space taken up by the heart. Each lung is separated into lobes branching off the main bronchus; the right lung has three lobes, while the left has only two lobes
definitions of lung capacity terminology
Total lung capacity, or TLC, refers to the total amount of air in the lungs after taking the deepest breath possible
breathing mechanism (physiology)
The action of breathing in and out is due to changes in pressure within the chest (thorax). This action is also known as external respiration and is created by the muscles of the chest and the diaphragm changing the size of the chest cavity (and air pressure)
disorders of the respiratory system
Chronic Obstructive Pulmonary Disease
Chronic bronchitis
Emphysema
Asthma
internal and external respiration
Internal Respiration
Internal respiration occurs in the metabolizing tissues, where oxygen diffuses out of the blood and carbon dioxide diffuses out of the cells
External Respiration
External respiration occurs in the lungs where oxygen diffuses into the blood and carbon dioxide diffuses into the alveolar air

Major functions of the
respiratory system
the exchange of oxygen from the atmosphere for carbon dioxide produced by the cells of the body.
