Human Anatomy & Physiology: The Respiratory System 2 - Quiz

I created these quizzes to help me study for my A&P exams. This quiz deals with the organs of the upper respiratory system.


Questions and Answers
  • 1. 

    The upper respiratory tract includes the _______, ___________, _________ and _________.

    Explanation
    The upper respiratory tract consists of the nose, nasal cavity, sinuses, and pharynx. These structures are responsible for the initial filtration, warming, and humidification of the inhaled air. The nose acts as the main entrance for air and is lined with tiny hairs and mucus-producing cells that help trap and remove foreign particles. The nasal cavity is a hollow space behind the nose that further filters and moistens the air. The sinuses are air-filled cavities located in the bones of the face, which help to lighten the skull and produce mucus. The pharynx is a muscular tube connecting the nasal cavity and mouth to the larynx and esophagus, serving as a passage for both air and food.

    Correct Answer
    E. Nasal hairs; large
    Explanation
    The nasal hairs, also known as cilia, provide the first line of defense in the respiratory tract. They help to prevent the entrance of relatively large particles by trapping them in the nasal cavity. The large size of the nasal hairs allows them to effectively filter out these particles and prevent them from entering further into the respiratory system.

  • 6. 

    The __________ are the delicate, scroll shaped bone plates that form the lateral walls of the nasal cavity.

    Correct Answer
    nasal conchae
    Explanation
    The nasal conchae are the delicate, scroll-shaped bone plates that form the lateral walls of the nasal cavity. They help to increase the surface area of the nasal cavity, which aids in the filtration, humidification, and warming of the inhaled air. The nasal conchae also play a role in directing the airflow within the nasal cavity, ensuring that the air is properly distributed and reaches all parts of the nasal passages.

    Rate this question:

  • 7. 

    The inferior & middle nasal conchae are covered by __________ and consist of a type of _______ that varies on location and a supporting layer of ________.

    Correct Answer
    respiratory mucosa, epithelium, connective tissue
    respiratory mucosa, epithelium, CT
    Explanation
    The inferior and middle nasal conchae are covered by respiratory mucosa, which is a specialized type of epithelium. This respiratory mucosa varies depending on its location within the nasal conchae. In addition to the epithelium, there is a supporting layer of connective tissue present.

    Rate this question:

  • 8. 

    The superior conchae are covered by specialized ____________ that contain receptors for __________.

    Correct Answer
    olfactory epithelium, sense of smell
    Explanation
    The superior conchae, which are structures in the nasal cavity, are covered by specialized tissue called olfactory epithelium. This tissue contains receptors that are responsible for the sense of smell. These receptors detect odor molecules in the air and send signals to the brain, allowing us to perceive different smells.

    Rate this question:

  • 9. 

    The nasal mucous membrane is composed of ____________________ that contains an abundance of mucus secreting __________.

    Correct Answer
    pseudostratified ciliated columnar epithelium, goblet cells
    Explanation
    The nasal mucous membrane is made up of a type of epithelium called pseudostratified ciliated columnar epithelium. This type of epithelium appears stratified, but all cells are in contact with the basement membrane. It is characterized by the presence of cilia, which help in moving mucus and trapped particles out of the nasal cavity. Goblet cells, which are specialized cells that secrete mucus, are also found in abundance in the nasal mucous membrane. These cells play a crucial role in trapping and removing foreign particles, as well as moisturizing and protecting the nasal passages.

    Rate this question:

  • 10. 

    The three functions of the nasal mucous membrane are that it _____ the incoming air, it _________ the incoming air by evaporation and it uses mucus to ___________.

    Correct Answer
    warms, moistens, entrap dust and other small particles
    Explanation
    The nasal mucous membrane has three main functions. Firstly, it warms the incoming air, ensuring that it reaches the lungs at a suitable temperature. Secondly, it moistens the air, preventing the respiratory system from becoming too dry. Lastly, the mucous membrane uses mucus to entrap dust and other small particles, preventing them from entering the lungs and causing potential harm.

    Rate this question:

  • 11. 

    Within the nasal mucous membrane, ___________ help to move the mucus with the trapped particles toward the ________. As the mucus reaches the back of the throat it is _________. ___________of the stomach will destroy most microbes and thus helps prevent ___________.

    Correct Answer
    cilia, pharynx, swallowed, gastric juices, respiratory infections
    Explanation
    The cilia within the nasal mucous membrane help to move the mucus with the trapped particles toward the pharynx. As the mucus reaches the back of the throat, it is swallowed. The gastric juices of the stomach will destroy most microbes and thus help prevent respiratory infections.
