High schools focus on primary rather than acute care and provide knowledge about health and health promotion that occurs outside traditional health care institutions, such as hospitals, reha-bilitation hospitals, and nursing homes.
Answer to Question 2
B
Respiration is the mechanism the body uses to exchange gases between the atmosphere, blood, and cells. Respiration involves three processes: ventilation (the mechanical movement of gases into and out of the lungs), diffusion (the movement of oxygen O2 and carbon dioxide CO2 between the alveoli and the red blood cells), and perfusion (the distribution of red blood cells to and from the pulmonary capillaries). The normal rate and depth of ventilation is known as eupnea.
