The entire system of air passages involved in breathing, especially the trachea, bronchial tubes, bronchioles, and alveoli.
The respiratory tract consists of the lungs and a series of air passages leading to and from the lungs. These passages are divided into the conducting portion (nasal cavities, pharynx, larynx, trachea, bronchi, and the bronchioles) and the respiratory portion (where gas exchange occurs between air and blood. It consists of the respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli.
The organs that are involved in breathing. These include the nose, throat, larynx, trachea, bronchi, and lungs. Also called the respiratory system.
the passages through which air enters and leaves the body
The upper respiratory tract includes the nose, sinuses, pharynx (throat), and larynx (voice box). The lower respiratory tract includes the trachea (windpipe), bronchial tubes (two branches from the windpipe), bronchioles (smaller bronchial tubes), and alveoli (tiny sacs in the lungs where the exchange of oxygen and carbon dioxide occurs).
Composed of the conducting airway including the nose, mouth, pharynx, larynx, trachea, bronchi, bronchioles, and alveoli.
organs responsible for carrying oxygen from the air to the bloodstream and for expelling the waste product, carbon dioxide. The respiratory tract includes the upper air passages, the lungs, and the muscles that control breathing.
Consists of the air passageways involved in breathing; for example the nose, larynx, trachea, and lungs.
The entire system of organs and tissues involved in breathing; especially the lungs, trachea, bronchial tubes, bronchioles and alveoli.
In humans the respiratory tract is the part of the anatomy that has to do with the process of respiration or breathing.
