RESPIRATORY SYSTEM LAB Flashcards
What is the function of the respiratory system?
the respiratory system provides oxygen the cells and removes carbon dioxide from the body
How do the cells use oxygen?
oxygen is used by the cells as a terminal electron receptor
What is carbon dioxide?
carbon dioxide is a waste product of cellular respiration
Describe the movement of atmospheric oxygen within the respiratory system.
atmospheric oxygen moves into the lungs and diffuses in the circulatory system
What is the result of too much carbon dioxide within the blood?
too much carbon dioxide within the blood increases the hydrogen ion concentration within the blood
What is the result of an increased hydrogen ion concentration in the blood?
an increased concentration of hydrogen ions causes acidosis of the blood
True or False: the respiratory system is integrated into other anatomical systems?
true; the respiratory system is integrated into other anatomical systems
What are the main organs of the respiratory system?
the main organs of the respiratory system are the nose, pharynx, larynx, trachea, bronchi, and lungs
Which of the main organs compose the upper respiratory system?
the nose, pharynx, and compose the upper respiratory airways
Which of the main organs compose the lower respiratory system?
the trachea, bronchi, and lungs make up the lower respiratory ariways
The framework of the nose is composed of what?
the framework of the nose is composed of bone a cartilage
What is anterior portion of the nose comprised of?
the anterior portion of the nose is comprised of hyaline cartilage
What is the posterior portion of the nose comprised of?
the posterior portion of the nose is compromised of bone
What are the initial openings of the respiratory system called?
the two initial opening of the respiratory system are called the external/ anterior nares
The external/ anterior nares lead to what?
the external nares lead to the nasal cavity
Describe the function of the nasal septum.
the nasal septum is responsible for separating the nasal cavity into right and left portions
Which part of the nasal cavity is highly vascularized and the sight of nosebleeds?
the nasal septum is highly vascularized and is the site of nosebleeds
What are the three curved, bony structures that extend into the nasal cavity?
the three curved, bony structures that extend into the nasal cavity are the superior, middle, and inferior nasal conchae/ turbinates
Describe the meatus.
the meatus is a concavity beneath each of the conchae which increases the surface area of the nose
What is the function of the meatuses?
the meatuses are responsible for warming and humidifying the air breathed in
What is the name of the palate that forms the floor of the nasal cavity?
the bony/ hard palate forms the floor of the nasal cavity
The nasal cavity ends with which two openings?
the nasal cavity ends with the internal/ posterior nares
The nasal cavity leads into which respiratory organ?
the nasal cavity leads into the pharynx
The pharynx is commonly known as what?
the pharynx is commonly known as the throat
The pharynx is divided into which three regions?
the pharynx is divided into the nasopharynx, oropharynx, and laryngopharynx
Describe where the nasopharynx begins and ends.
the nasopharynx begins at the external nares and ends at the soft palate
Describe where the oropharynx begins and ends.
the oropharynx begins at the soft palate and ends at the hyoid bone
Describe where the laryngopharynx begins and ends.
the laryngopharynx begins at the hyoid bone and ends at the esophagus
Where is the soft palate found?
the soft palate is found in the pharynx
Describe the anatomical position of the soft palate as it relates to the hard palate.
the soft palate is a posterior extension of the hard palate
Describe the anatomical position of the uvula as it relates to the soft palate.
the uvula is the oval-shaped tissue that dangles inferiorly as an extension of the soft palate
What is the function of the uvula?
the uvula is responsible preventing fluids from entering the nasopharynx during swallowing and directing food into the laryngopharynx
Which structures have openings from the middle ear into the nasopharynx?
the auditory tubes/ eustachian tubes have openings from the middle ear into the nasopharynx
Which tonsil is located on the posterior wall of the nasopharynx?
the pharyngeal tonsil/ adenoid tonsil is located on the posterior wall of the nasopharynx
The palatine and lingual tonsils are apart of which respiratory structure?
the palatine and lingual structures are apart of the oropharynx
How are infections able to be spread from the ears to the nose/ mouth?
infections are able to be spread throughout these areas because they are connected by ducts
The larynx is also known as what?
the larynx is also known as the “voice box”
