Answer:
1. The respiratory system allows us to breathe . They bring oxygen into our body and remove carbon dioxide from the body .
2. Tiny hairs called cilia protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.
3. The throat (pharynx and larynx) is a ring-like muscular tube that acts as the passageway for air, food and liquid. It is located behind the nose and mouth and connects the mouth (oral cavity) and nose to the breathing passages (trachea [windpipe] and lungs) and the esophagus (eating tube).
4. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled.
5. The heart pumps blood to the lungs for oxygenation and the lungs then give the heart back oxygen rich blood to be transmitted to the whole body

Answer:
The correct answer is ''the mechanisms for coordinating subunits.''
Explanation:
Integration mechanisms are explicitly defined to coordinate subunits. In turn, are divided into structural and non-structural mechanisms. Structural integration mechanisms coordinate activities and are usually linked to specific management positions or bodies. The non-structural integration mechanisms, for their part, are characterized because they do not create organs or positions, but they constitute a relevant complement to the structural mechanisms, facilitating the organization of work. Informal integration mechanisms or those aimed at facilitating informal relationships are the simplest and easiest to use. Individuals face a certain situation and, spontaneously, communicate with each other. If no further coordination is required, informal mechanisms may be sufficient
