Study Notes
Respiratory System Components
- The respiratory system consists of the nose, nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, and terminal bronchioles.
- These components work together to filter, warm, and moisten air and conduct it into the lungs.
Respiratory Zone
- The respiratory zone is composed of tubes and tissues within the lungs where gas exchange occurs.
- The wall of the respiratory zone is composed of skeletal muscles and is lined with a mucous membrane.
- Relaxed skeletal muscles help keep the pharynx patent.
Pharynx Functions
- The pharynx functions as a passageway for air and food.
- It provides a resonating chamber for speech sounds.
- It houses the tonsils, which participate in immunological reactions against foreign invaders.
- The pharynx is located anterior to the esophagus and extends from the larynx to the superior border of the fifth thoracic vertebra (T5), where it divides into right and left primary bronchi.
Pharynx and Skeletal Muscles
- Contraction of the skeletal muscles assists in deglutition (swallowing).
- The skeletal muscles also help in keeping the pharynx patent.
