  • What is the role of the diaphragm in breathing?
    It helps expand and contract the lungs.
  • What role do alveoli play in respiration?
    They are the site of gas exchange between air and blood.
  • What protein in red blood cells binds to oxygen?
    Hemoglobin.
  • Where does gas exchange occur in the lungs?
    In the alveoli.
  • What does "contract" mean when talking about muscles?
    Get shorter.
  • What is the primary function of respiration?
    To release energy from glucose.
  • What is the waste gas produced during respiration?
    Carbon dioxide.
  • What is the function of the respiratory system?
    To bring oxygen into the body and remove carbon dioxide.
  • What is the liquid part of the blood called?
    Plasma.
  • What is the function of hemoglobin in red blood cells?
    To carry oxygen.
  • What is the chemical formula for aerobic respiration?
    Glucose + Oxygen → Carbon Dioxide + Water + Energy (ATP).
  • During exhalation
    It relaxes and moves upward.
    what happens to the diaphragm?
  • What type of respiration requires oxygen?
    Aerobic respiration.
  • Which gas is needed for aerobic respiration?
    Oxygen.
  • What happens to oxygen after it enters the alveoli?
    It diffuses into the blood.
  • What type of respiration produces the most energy?
    Aerobic respiration.
  • What waste product is expelled during exhalation?
    Carbon dioxide.
  • What byproduct is released when glucose is broken down during aerobic respiration?
    Carbon dioxide.
  • What is the main function of white blood cells?
    To fight infections.
  • What is the main role of red blood cells?
    To carry oxygen from the lungs to the body.
  • What part of the blood carries nutrients and waste products?
    Plasma.
  • What happens to the diaphragm when you inhale?
    It contracts and moves downward.
  • Which type of respiration occurs in the absence of oxygen?
    Anaerobic respiration.
  • Where does aerobic respiration take place in the cell?
    Mitochondria.
  • What is the difference between breathing and respiration?
    Breathing is the physical process of moving air in and out , respiration is a series of chemical reactions that take place in every living cell.
  • What do white blood cells produce to kill pathogens?
    Antibodies.
  • What process allows oxygen to move from the alveoli into the blood?
    Diffusion.
  • What type of blood cell helps transport carbon dioxide back to the lungs?
    Red blood cells.
  • What are the products of aerobic respiration?
    Carbon dioxide, water and energy (ATP).
  • Which organelle is known as the "powerhouse of the cell"?
    Mitochondria.
