what are the parts and the function of the respiratory tract
The respiratory tract (or system) is a complex arrangement of organs and tissues. Its main functions are taking in oxygen and getting rid of carbon dioxide. The respiratory tract can be separated into two parts (see Figs. 1 and 2): (b) The distal respiratory region (i.e., respiratory bronchioles, alveolar ducts, and alveoli).
The respiratory system provides oxygen to the bodyâs cells while removing carbon dioxide, a waste product that can be lethal if allowed to accumulate. There are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration. The airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, carries air between the lungs and the bodyâs exterior. The lungs... Click to read more below. The cells of the human body require a constant stream of oxygen to stay alive.
