What is #13 pointing to?
Bronchi
Location where gas exchange occurs
Alveoli
Describe the function of the trachea
carry oxygen-rich air to your lungs from the pharynx/larynx
Bronchial spasm resulting in decreased air movement and air trapped in alveoli
asthma
Would a lung with oxygen drawn in - sink or float in a beaker of water?
Float
What is #15 pointing to?
Pharynx
Area at the back of the throat where the mouth and nasal cavity meet
pharynx
Flap of tissue which prevents food from entering windpipe during swallowing
Infection of the lungs caused by viruses, bacteria, or fungi. Alveoli fill with pus and fluid, making gas exchange difficult
Pneumonia
What happens to the size of the bronchioles as you go deeper into the lungs.
shrink
What is letter L pointing to
Diaphragm
Each lung is covered in a very thin membrane called
Pleura
This cartilage in the tracheal wall provides support and keeps the trachea from collapsing
Hyaline
Tubercles encapsulate bacteria, and elasticity of the lungs are reduced
Pulmonary Tuberculosis
tool that measures the amount of air you can breathe out in one second and the total volume of air you can exhale in one forced breath
spirometer
What is #4 pointing to?
Right (superior) upper lobe of the lung
What is a biopsy?
Describe what happens during inhalation by describing the movement of your diaphragm, lung volume, and air pressure
Diaphragm contracts = lung volume increases = air pressure decreases (air in)
Inflammation of the lining of the bronchial tubes
Bronchitis
Expired air will contain more ___________ than inspired air
CO2
What are the blood filled vessels that surround this structure called?
Capillaries
What is respiratory distress?
having to work harder to breathe or are not getting enough oxygen
Why would it be beneficial for alveoli to have a ton of surface area?
More capability for gas exchange
the body's reaction to a lack of oxygen, caused by ascent at a faster pace than acclimatization
Acute Mountain Sickness (altitude sickness)
How does emphysema affect the lungs?
Alveoli walls deteriorate
