Nose Flashcards
Nose, conchae, nasopharynx, oropharynx, laryngopharynx. (33 cards)
What are the functions of the nose in respiration?
Entry point for air, produce mucus to filter, warm and humidify the air.
What are conchae, where are they located, and what is their function?
Turbinates, they are located in the nose, and their purpose is to warm filter and humidify air.
Know what substances are supposed to pass through the 3 regions of the throat:
Nasopharynx- Air only
Oropharynx- Food, fluids, air
Laryngopharynx- Foods, and fluids
Why are the pleural membranes important for maintaining the health of your lungs?
- Create a vacuum in the lungs to keep them inflated.
- Prevents friction between lungs and chest cavity
What are the 3 functions of the sinuses?
- Filter air
- Act as a resonance chamber for speech
- Produce mucus
What are the functions of the larynx?
- Voice box
- Houses vocal cords
What structures make up the conducting zone?
- Nasal Cavity
- Sinuses
- Pharynx
- Larynx
- Trachea
What is the function of the conducting zone?
transport, warm, moisten, and filter air as it moves to the lungs.
What structures make up the respiratory zone?
Alveoli, bronchioles.
What process happens in the respiratory zone
Gas exchange.
Where are alveoli found, and what is their function during respiration?
End of the bronchioles in the lungs, gas exchange.
What is the order of structures that inhaled air passes through to get from the nose to alveoli in the lungs?
Nostrils/mouth, nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, alveoli
What is the role of the cardiovascular system in respiration?
Transports O2 and CO2 between the lungs and the body tissues.
What is the purpose of the surfactant produced by the cells in your lungs?
Coats the alveolar membranes and aids in gas exchange
What is the difference between the parietal and visceral pleural membranes?
Parietal-outer membrane lines inside of rib cage
Visceral-coats surface of lungs
Which protein found in red blood cells is necessary for transporting respiratory gasses?
Hemoglobin
What happens to the blood if the concentration of carbon dioxide is too high?
The blood starts to turn acidic
Which lung is smaller? Why is this the case?
Left lung because it only has 2 lobes
What are the 2 reasons that high altitudes make it difficult to breathe?
Reduced concentration of oxygen, decreases respiratory gases ability to diffuse.
What is the epiglottis, and what is its function?
A cartilage flap, directs food and fluids into the esophagus and air into the larynx
What are the two reasons that exercise increases your respiratory rate?
- More ATP needed = more O2 needed
- Increased CO2 production
When is a cough reflex triggered?
When anything other than air enters the larynx.
What is the main cause of emphysema?
Smoking
Which system is malfunctioning when you have an allergic reaction?
Immune system
