The Lungs And Breathing Quiz! Trivia - Quiz


What do you know about the lungs and breathing? Do you know enough to pass this quiz? The lungs are one of the essential parts of your body. Lungs are necessary for life because they allow you to breathe. One of the vital roles that your lungs perform is to intake air and oxygen that your body needs to survive. Take this quiz and find out exactly just how much you know about the lungs and breathing.


Questions and Answers
  • 1. 

    What needs oxygen to live and grow?

    • A.

      Carbon Dioxide

    • B.

      Cells

    • C.

      Respiratory System

    Correct Answer
    B. Cells
    Explanation
    Cells need oxygen to live and grow. Oxygen is necessary for cellular respiration, the process by which cells convert nutrients into energy. During cellular respiration, oxygen is used to break down glucose molecules and produce ATP, the energy currency of cells. Without oxygen, cells cannot generate enough energy to carry out their functions and eventually die. Therefore, cells rely on oxygen to support their metabolic activities and maintain their survival and growth.

    What is the trachea?

    • A.

      Food Pipe

    • B.

      Pumps Blood

    • C.

      Air Pipe

    Correct Answer
    C. Air Pipe
    Explanation
    The trachea is the air pipe in the human body. It is a tube-like structure that connects the larynx (voice box) to the bronchi in the lungs. Its main function is to allow the passage of air to and from the lungs during breathing. The trachea is lined with tiny hair-like structures called cilia, which help to filter and remove any foreign particles or debris from the inhaled air, protecting the lungs from damage.

    Rate this question:

  • 3. 

    Which of these is a function of the passage of air?

    • A.

      Allowing air to pass into the nose

    • B.

      Getting rid of carbon dioxide

    • C.

      Pumping Blood

    Correct Answer
    A. Allowing air to pass into the nose
    Explanation
    The passage of air is responsible for allowing air to pass into the nose. This is an important function as it allows oxygen to enter the respiratory system and reach the lungs for the process of respiration. The nose acts as a filter, warming and moisturizing the air before it enters the lungs. This process is essential for the exchange of gases and maintaining proper oxygen levels in the body.

    Rate this question:

  • 4. 

    Which of these is part of the respiratory system?

    • A.

      Heart

    • B.

      Ribs

    • C.

      Larynx

    Correct Answer
    C. Larynx
    Explanation
    The larynx is part of the respiratory system. It is commonly known as the voice box and is located in the throat. The larynx plays a crucial role in the production of sound and is responsible for protecting the airway during swallowing. It contains the vocal cords, which vibrate to produce speech and other vocal sounds. The heart and ribs are not part of the respiratory system. The heart is part of the circulatory system, and the ribs are part of the skeletal system.

  • 5. 

    All the cells of the body need ________ to live and grow.

    Correct Answer
    oxygen
    Explanation
    Oxygen is essential for the survival and growth of all cells in the body. It is required for cellular respiration, the process by which cells convert nutrients into energy. Oxygen is transported through the bloodstream to all tissues and organs, where it is used to produce ATP, the energy currency of the cell. Without oxygen, cells would not be able to carry out their metabolic functions and would eventually die. Therefore, oxygen is crucial for the maintenance and development of all cells in the body.

    Rate this question:

  • 6. 

    Another word for the throat is ________.

    Correct Answer
    pharynx
    Explanation
    The correct answer is "pharynx" because it is a medical term that refers to the part of the throat behind the mouth and nasal cavity. It is responsible for the passage of air and food, making it synonymous with the word "throat."

    Rate this question:

  • 7. 

    Living cells produce _________  __________ as a waste product.

    Correct Answer
    carbon dioxide
    Explanation
    Living cells produce carbon dioxide as a waste product. During cellular respiration, cells break down glucose to produce energy in the form of ATP. As a byproduct of this process, carbon dioxide is released. This waste gas is then transported to the lungs, where it is exhaled out of the body. Carbon dioxide plays a crucial role in maintaining the balance of gases in the atmosphere and is also an essential component of the carbon cycle.
