What are the four processes of respiration?

• Breathing, Metabolism, Filtration, Absorption
• Pulmonary ventilation, External respiration, Transport of gases, Internal respiration
• Inhalation, Exhalation, Digestion, Circulation
• Cellular respiration, Anaerobic respiration, Photosynthesis, Fermentation

What is the major difference between the conducting zone and the respiratory zone function?

• The conducting zone is responsible for gas exchange, while the respiratory zone transports air.
• The respiratory zone is a site of gas exchange & Conducting zone conduits that transport gas

• The conducting zone filters air, and the respiratory zone humidifies it.
• Both zones are involved in gas exchange but at different rates.

What are the functions of the nose?

• Warms, cleanses, and humidifies inhaled air

  – Detects odors

  – Serves as a resonating chamber that amplifies voice

• Producing tears
• Storing oxygen
• Regulating body temperature

Which cells produce mucus in the respiratory tract?

• Goblet cells
• Basal cells
• Alveolar cells
• Ciliated epithelial cells

What is the role of the nasal conchae?

• Conchae create turbulence that ensures most air contacts mucous membranes to enhance

  cleansing, warming, and moistening the air

• To enhance the sense of smell.
• To produce mucus for the throat.
• To support the structure of the skull.

What are the functions of the larynx?

• Regulating body temperature during exercise
• Producing hormones for growth
• Filtering dust from the air during inhalation
• Provides patent airway

  Routes air and food into proper channels

  Voice production - houses vocal folds

What structure of the larynx is involved in speech production?

• Vocal cords (vocal folds)
• Cricoid cartilage
• Thyroid cartilage
• Epiglottis

What are the anatomical differences between the left and right main bronchi?

• Both main bronchi are identical in length and angle.
• The left main bronchus is shorter and more vertical than the right.
• Right main bronchus wider, shorter, more vertical than left

• The right main bronchus is longer and more horizontal than the left.

What are the respiratory zone structures?

• respiratory bronchioles, which lead into alveolar ducts and finally into alveolar sacs

• Nasal cavity and pharynx
• Lungs and diaphragm
• Trachea and bronchi

Where in the respiratory system is the main site of gas exchange?

• Alveoli
• Lungs
• Trachea
• Bronchi
