In the adult‚ this hollow tube is about 9 meters (29 feet) long Think of the tube as a passageway that extends through the body like a hallway through a building.

Discuss how a feedback loop would benefit a change initiative within an organization. Most systems have feedback loops‚ which enforce communication in some type of way. If an organization implements a

The respiratory system is composed of the nasal cavity‚ nostril‚ oral cavity‚ pharynx‚ larynx‚ trachea‚ carina of trachea‚ right main bronchus‚ right lung‚ left main bronchus‚ left lung‚ and diaphragm. These major organs collectively work together to give the body oxygen and eliminate carbon dioxide as we breathe. In order for the respiratory system to be fully capable of function‚ four procedures (pulmonary ventilation‚ external respiration‚ transport of respiratory gases‚ internal respiration)
