Answer:

a)to move air toward the lungs while warming, moistening, and filtering it

Explanation:

The respiratory system consists of the upper and lower respiratory tract (airways). The upper respiratory tract consists of organs located outside the rib cage: external nose, nasal cavity, pharynx, larynx and upper trachea. These organs are responsible for the entry of oxygen into the body, so we can say that the function of the upper respiratory system is to move the air in the environment towards the lungs while heating, moistening and filtering.

The Needlestick Safety and Prevention Act (the Act) (Pub. L. 106-430) was signed into law on November 6, 2000. Because occupational exposure to bloodborne pathogens from accidental sharps injuries in healthcare and other occupational settings continues to be a serious problem, Congress felt that a modification to OSHA's Bloodborne Pathogens Standard was appropriate (29 CFR 1910.1030) to set forth in greater detail (and make more specific) OSHA's requirement for employers to identify, evaluate, and implement safer medical devices. The Act also mandated additional requirements for maintaining a sharps injury log and for the involvement of non-managerial healthcare workers in evaluating and choosing devices.
