What are the parts of the upper and lower respiratory tract?

What are the parts of the upper and lower respiratory tract?

The upper respiratory tract consists of the nose, the nasal cavity and the pharynx. The lower tract consists of the larynx, the trachea , the bronchi and the lungs. The trachea, which begins at the edge of the larynx, divides into two bronchi and continues into the lungs.

What part of the respiratory system is in the lower respiratory?

The lower respiratory system, or lower respiratory tract, consists of the trachea, the bronchi and bronchioles, and the alveoli, which make up the lungs. These structures pull in air from the upper respiratory system, absorb the oxygen, and release carbon dioxide in exchange.

Is the diaphragm part of the lower respiratory tract?

Lower respiratory tract: Composed of the trachea, the lungs, and all segments of the bronchial tree (including the alveoli), the organs of the lower respiratory tract are located inside the chest cavity. Diaphragm: The diaphragm is the main respiratory muscle that contracts and relaxes to allow air into the lungs.

Which of the following best describes the main function of the lower respiratory tract?

A )Explanation: The lower respiratory tract consists of the windpipe, the bronchi, bronchioles, and the alveoli. Alveoli form the site for exchange of gases (absorb oxygen and release carbon dioxide) between air and blood.

What are the structures of the lower respiratory system?

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.

Where does the lower respiratory tract take place?

Lower respiratory tract infections occur in the lower respiratory system’s anatomical structures and organs, including the larynx below the vocal folds, trachea or windpipe, lungs, bronchi, bronchioles, alveoli, and diaphragm.

How are the lungs part of the respiratory system?

The trachea, bronchi, and lungs are part of the lower respiratory system. The lungs are responsible for moving air throughout the upper and lower respiratory tract. They draw in air when contracting muscles cause them to expand. The difference in air pressure that results causes air to be drawn into the lungs.

Is the trachea part of the upper respiratory system?

This exchange of gases is the primary function of the respiratory system. The trachea, bronchi, and lungs are part of the lower respiratory system. When air is inhaled, it first passes through the upper respiratory system.
