Review Questions

• What are some common medical conditions that use the suffix -penia, and how do they impact health?
  • -penia is commonly found in terms like agranulocytopenia, thrombocytopenia, and leukopenia. Each condition represents a deficiency in specific blood cells—granulocytes, platelets, and white blood cells, respectively. The impact on health includes increased risk of infections from agranulocytopenia, bleeding issues due to thrombocytopenia, and overall impaired immune response from leukopenia.
• Analyze how the prefix combined with -penia specifies the type of deficiency present in the body.
  • The prefix preceding -penia is crucial because it directly indicates what specific component is deficient. For example, 'leuko-' refers to white blood cells, while 'thrombocyto-' pertains to platelets.
