    The                             is a shared pathway that traps and destroys pathogens

    • Larynx

    • Pharynx

    Correct Answer
    A. Pharynx
    Explanation
    The pharynx is a shared pathway that traps and destroys pathogens. The pharynx is a part of the throat that connects the nasal cavity and the larynx. It serves as a passage for both air and food. The pharynx contains specialized cells and immune system components that help to trap and destroy pathogens, such as bacteria and viruses, that may enter the body through the respiratory or digestive systems. This defense mechanism helps to prevent infections and keep the body healthy.

    The larynx contains the                               to keep food and fluids from going down wrong tube

    Correct Answer
    epiglottis
    Explanation
    The larynx contains the epiglottis, which is a flap of cartilage that covers the opening of the trachea during swallowing. This prevents food and fluids from entering the windpipe and going down the wrong tube.

    Factors that affect O2 transport are                  

    • Cardiac output

    • Number of rbc men have higher count

    • Blood hematocrit

    • Excercise, 20X normal rate

    • All the above

    Correct Answer
    A. All the above
    Explanation
    The factors that affect O2 transport are cardiac output, number of RBC (men have higher count), blood hematocrit, and exercise at 20X normal rate. All of these factors can influence the amount of oxygen that is transported in the blood. Cardiac output determines the amount of blood that is pumped by the heart, which affects the delivery of oxygen to tissues. The number of RBCs and blood hematocrit determine the oxygen-carrying capacity of the blood. Exercise increases the demand for oxygen, leading to an increased transport of oxygen. Therefore, all of the mentioned factors can affect O2 transport.

    The upper respiratory systems includes the mouth, nose, pharynx, and ?

    • Trachea

    • Lungs

    • Larynx

    • Bronchi

    Correct Answer
    A. Larynx
    Explanation
    The upper respiratory system includes the mouth, nose, pharynx, and larynx. The larynx, also known as the voice box, is a part of the respiratory system that plays a crucial role in producing sound and protecting the airway during swallowing. It is located between the pharynx and the trachea. The trachea, lungs, and bronchi are part of the lower respiratory system, which is responsible for the exchange of oxygen and carbon dioxide in the body.

                                levels stimulate breathing

    • Oxygen

    • Co2

    Correct Answer
    A. Co2
    Explanation
    CO2 levels stimulate breathing.

    Rate this question:

  • 7. 

                           low blood 02 will secondarily stimulate breathing

    Correct Answer
    hypoxemia
    Explanation
    Hypoxemia refers to a low level of oxygen in the blood. When the blood oxygen level is low, it can stimulate the body to increase its breathing rate in order to bring in more oxygen. This is a secondary response, meaning that it is a result of the low blood oxygen level.

    Rate this question:

  • 8. 

                                 is the movement of air between the atmosphere and the alveoli of the lungs.

    • Gas exchange

    • Transport of O2

    • Ventilation

    Correct Answer
    A. Ventilation
    Explanation
    Ventilation refers to the movement of air between the atmosphere and the alveoli of the lungs. It involves the process of inhalation and exhalation, where air is drawn into the lungs and then expelled. This movement of air allows for the exchange of gases, including the intake of oxygen (O2) and the release of carbon dioxide (CO2). Ventilation is essential for maintaining proper oxygen levels in the body and removing waste gases. Gas exchange and the transport of O2 are also important processes that occur during ventilation, but they specifically refer to the exchange and transportation of gases within the lungs and bloodstream, respectively.

  • 9. 

    The lower respiratory systems is                           and                         

    Correct Answer
    trachea and lungs
    Explanation
    The lower respiratory system consists of the trachea and lungs. The trachea, also known as the windpipe, is a tube that connects the upper respiratory system (nose and mouth) to the lungs. It allows air to pass through and reach the lungs for gas exchange. The lungs are the main organs of respiration, responsible for taking in oxygen and expelling carbon dioxide. Together, the trachea and lungs play a crucial role in the process of breathing and ensuring the exchange of gases in the body.

  • 10. 

    What portion of the airway is most prone to obstruction

    • Pharynx

    • Larynx

    • Trachea

    • Mouth

    Correct Answer
    A. Larynx
    Explanation
    because it is narrow

    Rate this question:

  • 11. 

    Pulmonary ventilation is also called                                  .

    Correct Answer
    active breathing
    Explanation
    Pulmonary ventilation refers to the process of breathing, which involves the movement of air in and out of the lungs. It is an active process that requires the contraction of the diaphragm and other respiratory muscles to expand the chest cavity and create a pressure gradient for air to flow in and out of the lungs. Therefore, the term "active breathing" accurately describes pulmonary ventilation.

    Rate this question:

  • 12. 

    Poor peripherial perfusion increases the risk for hypoxemia

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Poor peripheral perfusion refers to inadequate blood flow to the peripheral tissues, which can lead to tissue hypoxia. However, this does not necessarily increase the risk for hypoxemia (low oxygen levels in the blood). Hypoxemia can occur due to various reasons such as lung diseases, respiratory distress, or inadequate oxygen intake. While poor peripheral perfusion may contribute to tissue hypoxia, it does not directly increase the risk for hypoxemia. Therefore, the correct answer is false.

  • 13. 

                                      transport of O2 from lungs to tissue and CO2 from tissues back to lungs.

    Correct Answer
    transport of O2 and CO2
    Explanation
    The given correct answer states that the function being described is the transport of O2 and CO2. This means that the process mentioned is responsible for carrying oxygen from the lungs to the tissues in the body, and also for transporting carbon dioxide from the tissues back to the lungs for elimination. This process is essential for maintaining the body's oxygen levels and removing waste carbon dioxide.

    The respiratory center is in the                             and                       of brain

    Correct Answer
    medulla and pons of brain
    Explanation
    The respiratory center, which controls the rate and depth of breathing, is located in the medulla and pons of the brain. These regions are responsible for coordinating the muscles involved in respiration and regulating the levels of oxygen and carbon dioxide in the blood. The medulla and pons work together to ensure the proper functioning of the respiratory system, allowing us to breathe efficiently.

  • 16. 

                                    the diffusion of oxygen from alveoli into the pulmonary blood vessels.

    Correct Answer
    alvelolar gas exchange
    Explanation
    The alveolar gas exchange refers to the process of oxygen diffusing from the alveoli (tiny air sacs in the lungs) into the pulmonary blood vessels. This exchange occurs due to the concentration gradient between the oxygen-rich alveolar air and the oxygen-poor blood in the pulmonary capillaries. Oxygen molecules move across the thin walls of the alveoli and into the bloodstream, where they can be transported to the body's tissues for cellular respiration. This process is essential for ensuring that oxygen is effectively delivered to the body's cells and carbon dioxide is removed from the bloodstream.

    Rate this question:

  • 17. 

    Pulmonary ventilation includes Inhalation, exhalation, lung               and                              .

    Correct Answer
    compliance, lung recoil
    Explanation
    Pulmonary ventilation refers to the process of breathing, which involves both inhalation and exhalation. Compliance refers to the ability of the lungs to expand and contract easily, allowing air to flow in and out. Lung recoil refers to the natural tendency of the lungs to return to their resting state after being stretched during inhalation. Both compliance and lung recoil are important factors in ensuring efficient and effective pulmonary ventilation.
