Unit 3: Transportation Systems: Respiratory System Flashcards
How does the respiratory system function in warming, moistening, and filtering incoming air
The mouth, nose, and nasal cavity warms, moistens, and filters the air as it enters the body
What are the three functions of the respiratory system
- Warm, moisten, and filter incoming air
- Provides resonating chambers used on speech and sound production
- Carbon dioxide exchange
How does the respiratory system function in providing resonating chambers used in speech and sound production
Larynx generates sound
Nose provides a resonating chamber for speech sounds
How does the respiratory system function in carbon dioxide and gas exchange
Alveoli serve as a site of gas exchange (O2 and Co2) between the air and blood
Provide openings into the nose
Nares or nostrils
What are structures in the framework of the nose
Bony framework, cartilage, skin, and mucous membrane
What is the septum of the nose
Piece of cartilage that separates the nostrils into right and left sides. Like the septum of the heart
What is the function of the nose
Warm, moisten, and filter incoming air, smell, and provide resonating chambers used in speech and sound
Large, air filled space above and behind the nose in the middle of the face
Nasal cavity
Where air is warmed, filtered, and humidified
Nasal cavity
where are nerve endings that provide the sense or smell located
upper part of the nasal cavity
funnel-shaped tube about 13cm (5 inches) long
pharynx
where is the pharynx located
behind the mouth and nasal cavity, and above the larynx
what are the three sections of the pharynx
nasopharynx, oropharynx, and the laryngopharynx
serves as a passage way for air, water, and food
pharynx
resonate chambers for speech and sounds and assists in the formation of words
nose, pharynx
a large leaf-shaped place of cartilage that covers the larynx during swallowing to prevent food from entering the larynx
epiglottis
opening through the larynx (voice box) for the passage of air
epiglottis
below the pharynx, contains vocal cords, connects the pharynx and the trachea
larynx (voice box)
tubular passageway for air about 4.5 inches in length. located anterior to the esophagus, and passageway for air
trachea (windpipe)
large sets of branches that come off the trachea and enter the lungs, passageway for air
bronchi
what bronchi is more vertical, wider, and shorter than the left which means inhaled objects are more likely to get lodged in
right bronchi
bronchi divide to form smaller tubes called
bronchioles
serve as site of gas exchange (O2 and Co2) between the air and blood
alveoli
