Cesar Perez Period.1 Respiratory System
Major functions of the respiratory system
phonation
pulmonary defense and metabolism
acid-base balance
gas exchange
Allows you to talk and smell
warms air to match your body
Volume and Pressure relationships in thoracic cavity
Lung volume expands
Increasing the volume of the thoracic cavity causes a decrease in the intrathoracic pressure
air rushes into the lungs
Lower respiratory structures and functions
release carbon dioxide in exchange
windpipe
Absorbs the oxygen
bronchioles
alveoli
bronchi
Respiratory volumes and capacities
Inspiratory reserve (IRV)
Expiratory reserve (ERV)
Tidal (TV)
Residual volumes (RV)
Upper respiratory structures and functions
mouth
throat
nasal cavity
voice box
nose
Provides a passage for air to be breathed in and out of lungs
Contains vocal cords
Disorders of the respiratory system
Pneumonia
Lung cancer
Pulmonary fibrosis
Chronic obstructive pulmonary disease
Asthma
Compare and contrast the mechanism of inspiration and expiration
Diaphragm and intercostal muscle contract
allows air to enter the lungs
The inspiration muscles relax forcing gases to flow out of lungs
Inspiration is the process of drawing air inside the lungs
Expiration is a process of releasing air out
Layers of the pleurae
The inner layer wraps around the lungs
The outer layer lines the inside of the chest wall
Internal vs. external respiration
External moves gases from outside the body into the lungs
Internal is the gas exchange between the blood and tissues
Internal exchanges gases
External exchanges gases
