  • Q2
    Which of the following is true of the digestive system?
    It includes the mouth, lungs, esophagus, and stomach
    It gives our bodies a place to exchange carbon dioxide and oxygen
    It is responsible for physically and chemically breaking food into usable parts
    It relies only on the action of chemicals in the small intestine to get nutrients

  • Q3
    The correct level of organization found in humans is…
    Skin, muscles and bone are the basic building units
    Organs form tissues which form cells which form organelles
    All of the above depending on the age of the person
    Cells form tissues which form organs which form organ systems

  • Q4
    In the human respiratory system, there are structures called cilia. Why are these important?
    They warm and moisten the air we breathe
    They trap and filter dust and debris
    They are the place of gas exchange in our lungs
    They are the branches of the bronchial tree

  • Q5
    When air moves into your respiratory system, what pathway is followed?
    Mouth and nose -> Pharynx -> Trachea -> Right and left bronchi -> Bronchi -> Bronchioles -> Alveoli
    Diaphragm -> Trachea -> Lungs -> Alveoli -> Bronchus -> Cilia -> Small intestine -> Anus
    Mouth and nose -> Cilia -> Bronchioles -> Alveoli -> Bronchial tree
    Mouth -> Pharynx -> Esophagus -> Stomach -> Small intestine -> Liver -> Large intestine -> Anus

  • Q6
    Which of the following is NOT true of cellular respiration?
    It produces carbon dioxide and energy as a product
    It converts nutrient energy into usable energy
    It requires carbon dioxide to occur
    It can be either aerobic or anaerobic
    120s
  • Q7
    Which of the following are examples of accessory organs?
    The pancreas and liver
    The T-cells and B-cells
    All of the above
    The mouth and stomach

  • Q8
    Once absorption of nutrients occurs through the villi in the small intestine, what happens to them?
    The cilia trap them and move them where they need to go
    The nucleus of a cell converts them to tissues
    The bloodstream transports them to cells for cellular respiration
    The body excretes them
    120s
  • Q9
    Where in the respiratory system does the exchange of oxygen and carbon dioxide take place?
    It happens at the alveoli that are surrounded by blood vessels
    It first occurs in the trachea which is the main air tube
    The cilia are responsible for this function as well as exhalation
    It occurs throughout the bronchial tree in the lungs

  • Q10
    During a viral infection, which of the following occurs?
    The natural killer cells destroy infected cells and non-infected cells
    A fever might develop to help slow down the reproduction of the virus
    The T-cells and B-cells are called into action and antibodies are produced
    All of the above
    120s
  • Q11
    What happens during inhalation?
    The muscles in the bronchial tree relax and air pressure in the lungs increases as the chest cavity gets smaller.
    The diaphragm contracts which increases the size of the chest cavity. This lowers the pressure inside the lungs so air rushes in.
    The esophagus and the pharynx work together to move air into the bronchial tree.
    The trachea contracts and relaxes in rhythmic waves to pull air into the chest cavity.

  • Q12
    Which of the following is NOT true of the small intestine?
    It contains structures called villi to increase its surface area
    It is where most nutrients are absorbed
    It is where the feces are formed and stored
    It is longer in length than the large intestine
    120s
  • Q13
    The wavelike contractions of smooth muscle that move food down the esophagus are called...
    Digestion
    Absorption
    Peristalsis
    Excretion
    120s
  • Q14
    Your body needs vitamins because ...
    they provide the building material of muscle
    they help carry out chemical reactions
    they are a main energy source
    they insulate the body’s organs
    120s
  • Q15
    Where does digestion begin?
    In the mouth
    In the small intestine
    In the liver
    In the stomach
