The Respiratory System Quiz

Study Notes

Organs of the Respiratory System

Respiratory system includes nasal cavity, pharynx, larynx, trachea, bronchial tree, and alveoli of the lungs.

Main Functions of the Respiratory System

Facilitates gas exchange, supplying oxygen to the body and removing carbon dioxide.
Assists in regulating blood pH through gas concentrations.
Provides vocalization through laryngeal structures.

Role of the Larynx

Acts as a passageway for air between the pharynx and trachea.
Contains vocal folds, enabling sound production, essential for speech.

Components of the Conducting Airways

Comprises nasal cavity, pharynx, larynx, trachea, bronchi, and bronchioles.
Responsible for filtering, humidifying, and conducting air to the lungs.

Medical Conditions Affecting Upper Respiratory Pathways

Common colds, sinusitis, and allergies can cause inflammation and obstruction.
Infections such as pharyngitis and laryngitis may impact airway function.

Organ Responsible for Sense of Smell

Olfactory bulbs located in the nasal cavity are responsible for detecting odors.

Function of the Pleurae

Pleurae are membranes surrounding the lungs, providing lubrication and reducing friction during breathing.
Help maintain negative pressure for lung expansion during inhalation.

Structure Connecting Larynx to Bronchial Tree

Trachea serves as the direct connection, branching into bronchi that lead to the lungs.

Function of the Bronchial Tree

Distributes air throughout the lungs via bronchi and bronchioles, further facilitating gas exchange.

Main Function of the Pharynx

Acts as a pathway for air to move from the nasal cavity to the larynx while also enabling the passage of food to the esophagus.
