Explanation:
The absolute risk (AR) of a disease refers to the risk of developing the disease over a given time period. In this case, the absolute risk of the newborn African American child having sickle cell anemia is equal to 1 individual with the disease over 700 individuals >> AR = 1 / 700 = 0.0014. Moreover, the Relative Risk (RR) is calculated by comparing the likelihood of the absolute risk occurring between two distinct groups. In this case, the relative risk for the newborn African American having sickle cell anemia compared to a newborn European American child can be calculated by dividing the absolute risk of the newborn European American child with the measured absolute risk of the newborn African American child >> RR = 0.0000625 / 0.0014 = 0.0044.
The lungs are <em>separated by the mediastinum</em>. This anatomical region is the central compartment o f the thoracic cavity. It is located between the lungs and contains all the principal tissues and organs of the chest such as the heart, trachea, esophagus, thymus etc. The lungs are the only chest organs not contained in this region.
It is surrounded by the breastbone, vertebral column and is bounded laterally by the pericardium as well as being continuous with the loose connectinve tissue of the neck.
