What are the functions of the respiratory system?
The functions of the respiratory system include absorbing oxygen into the blood, removing carbon dioxide from the blood, maintaining acid-base balance, olfaction, speech, and expulsion of abdominal gases.
What is the functional classification of the respiratory conducting zone and respiratory zone?
The respiratory conducting zone includes organs that move air but are not involved in gas exchange, such as the nose to terminal bronchioles, which cleans, warms, and humidifies air. The respiratory zone includes organs involved in gas exchange, from respiratory bronchioles to alveoli.
What are the structural classifications of the upper and lower respiratory tracts?
The upper respiratory tract includes the nose, paranasal sinuses, pharynx, and larynx. The lower respiratory tract includes the trachea, bronchi, and lungs.
How could the classifications of the respiratory system help in describing diseases like rhinovirus (common cold) and pneumonia?
The classifications can help in identifying the specific part of the respiratory system affected by the disease. For example, rhinovirus primarily affects the upper respiratory tract, while pneumonia often involves the lower respiratory tract.
Describe the nose and nasal cavity.

The parts of the small intestine are the duodenum, jejunum, and ileum.
What is the function of the lower esophageal sphincter?
The function of the lower esophageal sphincter is to prevent the backflow of stomach contents into the esophagus.
