Identify respiratory structures

• What is the name of the respiratory system structure labeled as "Right Bronchus"?

  Right Bronchus
• What are the names of the main bronchi that branch off from the trachea?

  • Right superior lobar bronchus
  • Left superior lobar bronchus
• What is the name of the cartilage located between the cricoid and thyroid cartilages?

  Cricothyroid ligament
• What is the primary function of the cartilage rings in the trachea?

  To keep the trachea open during breathing
• What is the name of the respiratory system structure labeled as "Pleura"?


  Pleura
• What is the name of the cartilage located at the base of the trachea?

  Cricoid cartilage
• What is the name of the respiratory system structure labeled as "Right Lung"?

  Right Lung
• What is the role of the alveoli in the respiratory system?

  • Site of gas exchange between air and blood
  • Oxygen diffuses from alveoli into blood
  • Carbon dioxide diffuses from blood into alveoli
• What is the function of the tracheal cartilages?

  • They provide structural support to keep the trachea open
  • They allow the trachea to be flexible and bend
• What is the name of the respiratory system structure labeled as "Pleural Space"?

  Pleural Space
• What is the name of the respiratory system structure labeled as "Tonsils"?

  Tonsils
• What is the name of the respiratory system structure labeled as "Pharynx"?

  Pharynx
• What is the name of the bronchus that branches off the trachea to supply the superior lobe of the left lung?

  Left superior lobar bronchus
• How do the structures shown in the image work together to facilitate respiration?

  Blood vessels transport oxygen and carbon dioxide, respiratory bronchioles connect to alveolar ducts which lead to alveoli where gas exchange occurs
• How do the cartilage rings and mucus production work together in the trachea?

  Cartilage rings keep it open, mucus traps dirt
• What does the trachea extend from?

  Larynx (voice box)
• What is the name of the respiratory system structure labeled as "Epiglottis"?

  Epiglottis
• How do the bronchi further divide within the lungs?

  The bronchi branch into smaller bronchi and then into bronchioles
• What is the name of the respiratory system structure labeled as "Adenoids"?

  Adenoids
• Where does the trachea split?

  Into two main bronchi
• What is the name of the ligament that connects the cricoid and thyroid cartilages?

  Cricothyroid ligament
• What is another name for the trachea?

  Windpipe
• What are alveoli?

  Tiny air sacs in the lungs
• What is the name of the respiratory system structure labeled as "Ribs"?

  Ribs
• What is the name of the respiratory system structure labeled as "Diaphragm"?


  Diaphragm
• How are alveoli structured?

  They are clustered like grapes on a vine
• What surrounds the alveoli?

  Blood vessels
• What is the name of the respiratory system structure labeled as "Left Bronchus"?

  Left Bronchus
• How do the bronchi branch further into the lungs?

  • The main bronchi branch into smaller bronchi (e.g. right and left main bronchi, segmental bronchi)
  • The bronchi then branch into bronchioles which further divide into alveolar ducts and alveoli
• How does the frequency of cartilage rings change as bronchi branch?

  They become less frequent
• If a person has damaged alveoli, how would this affect their respiratory function?

  • Reduced gas exchange capacity
  • Decreased oxygen absorption into the bloodstream
  • Impaired ability to expel carbon dioxide from the body
• What role do capillaries play in the function of alveoli?

  They provide direct contact for gas exchange
• If you wanted to observe the detailed surface structure of the alveoli, which type of microscope would you use?

  Scanning electron microscope (SEM)
• How do bronchioles differ from bronchi?

  Bronchioles lack cartilage rings
• What supports the larger airways of the bronchi?

  Cartilage rings
• What is the name of the cartilage located at the top of the trachea?

  Cricoid cartilage
• How does the structure of alveoli facilitate gas exchange?

  Thin walls and large surface area enhance exchange
• What is the function of the tracheal cartilages?

  They provide structural support to keep the trachea open
• What is the name of the main airway structure shown in the image?

  Trachea
• What are the main functions of the lungs?

  • Gas exchange: Oxygen uptake and carbon dioxide removal
  • Regulate breathing and respiration
  • Protect the body from airborne pathogens
