Respiratory System Flashcards
During the process of inspiration, volume in the lungs _____________ , causing pressure in the lungs to _____________.
increases, decrease.
What causes voice changes after puberty?
vocal cords grow longer
What is the purpose of the cartilaginous rings that surround the trachea?
To prevent the trachea from collapsing between breaths
Blowing out birthday candles- demonstrates which lung volume?
expiratory reserve volume
What are the functions of paranasal sinuses?
lighten the skull, resonate speech and produce mucus
Vocal cords
produce sound when air passes over them
Cilia
responsible for moving foreign particles towards the throat
The 2 respiratory control groups that collect sensory information and control regular, quiet breathing are located in the:
pons & medulla
Epiglottis
involved in both respiratory and digestive systems
Which of the following describes the path of carbon dioxide as it leaves your capillaries and exits through the respiratory system?
alveoli, bronchioles, bronchi, trachea, larynx, pharynx, mouth/nose
Your respiratory rate increases with exercise because
your cells are building up more carbon dioxide.
Conchae
increase air turbulence in the nasal cavity
Tonsils and alveolar macrophages are found within the respiratory system, but function as part of the
lymphatic system
The amount of air that is regularly being exchanged through your lungs during this time is called the
tidal volume
Trachea
surrounded by cartilage
What is included in the upper respiratory system?
nasal cavity, pharynx, larynx, trachea
What connects the nose and the throat?
nasopharynx
What does our larynx allow us to do?
Speak
Sinuses
found above the nasal cavity
The largest cartilaginous portion of the larynx that is prominent in men and commonly called the “Adam’s apple” is
the thyroid cartilage
Alveoli
found in the respiratory zone
Function of the pleural fluid is
to reduce friction on surrounding tissues
The cartilaginous rings are U-shaped, on the trachea. They are open on one side to allow movement of
the esophagus
Where is the respiratory membrane/zone found?
between the capillary and each alveolus
Inspiration
Diaphragm contracts-> increase in volume of lungs-> decrease in pressure within lungs-> air rushes in
Expiration
Diaphragm relaxes-> decrease in volume of the lungs -> increase in pressure within lungs -> air rushes out
