Answer to Question 1

Hypersensitivity: increased responsiveness or abnormal reaction to a foreign material such as an allergic or transfusion reaction
Immunity: resistance to disease provided by the body's defense system

Answer to Question 2

The liver becomes swollen because of fatty liver change or an increased accumulation of fat droplets in the cytoplasm due to the impairment of enzyme systems that metabolize fat. This is an initial reaction to injury. If the offending organism is not eliminated, the liver eventually undergoes scarring or cirrhosis as a result of chronic inflammatory process.
