What are the structures of the upper respiratory tract?
The major passages and structures of the upper respiratory tract include the nose or nostrils, nasal cavity, mouth, throat (pharynx), and voice box (larynx). The respiratory system is lined with a mucous membrane that secretes mucus.
What structures are part of the lower respiratory tract?
The major passages and structures of the lower respiratory tract include the windpipe (trachea) and within the lungs, the bronchi, bronchioles, and alveoli. Deep in the lungs, each bronchus divides into secondary and tertiary bronchi, which continue to branch to smaller airways called the bronchioles.
Which of the following structures are part of both the lower respiratory tract and the respiratory division of the respiratory system?
The pharynx has dual functions: both air and food (or other swallowed substances) pass through it, so it is part of both the respiratory and digestive systems. Air passes from the nasal cavity through the pharynx to the larynx (as well as in the opposite direction).
What are the 5 main structures in the respiratory system?
These are the parts:
- Nose.
- Mouth.
- Throat (pharynx)
- Voice box (larynx)
- Windpipe (trachea)
- Large airways (bronchi)
- Small airways (bronchioles)
- Lungs.
Which of the following structures is located in the lower respiratory tract quizlet?
The lower respiratory tract consists of the trachea, bronchi, bronchioles, and lungs.
What structures are used by both the respiratory and digestive system?
pharynx, (Greek: “throat”) cone-shaped passageway leading from the oral and nasal cavities in the head to the esophagus and larynx. The pharynx chamber serves both respiratory and digestive functions.
What are the major structures of the respiratory system and their functions?
Pharynx (throat): Tube that delivers air from your mouth and nose to the trachea (windpipe). Trachea: Passage connecting your throat and lungs. Bronchial tubes: Tubes at the bottom of your windpipe that connect into each lung. Lungs: Two organs that remove oxygen from the air and pass it into your blood.
What is the first structure in this respiratory sequence?
The respiratory system starts at the nose and mouth and continues through the airways and the lungs. Air enters the respiratory system through the nose and mouth and passes down the throat (pharynx) and through the voice box, or larynx.
What structures make up the upper and lower respiratory tracts quizlet?
Structurally, the respiratory system consists of two parts: (1) The upper respiratory system includes the nose, nasal cavity, pharynx, and associated structures. (2) The lower respiratory system includes the larynx, trachea, bronchi, and lungs.
What are the structures of the upper respiratory tract quizlet?
Nasal cavity, nasopharynx, pharynx, larynx.
What structures are used by both the respiratory and digestive system quizlet?
The pharynx, commonly called the throat, is a passageway that extends from the base of the skull to the level of the sixth cervical vertebra. It serves both the respiratory and digestive systems by receiving air from the nasal cavity and air, food, and water from the oral cavity.
