What does the suffix -emia refer to?

The suffix -emia refers specifically to a condition related to the blood. In medical terminology, it is commonly used to denote the presence of a substance in the blood or a blood-related disorder. For example, "anemia" refers to a deficiency of red blood cells or hemoglobin in the blood, while "leukemia" refers to a type of cancer that affects the blood and bone marrow. Understanding this suffix is crucial for medical professionals, as it helps in identifying various blood disorders and conditions that may require clinical attention or intervention.

The other options are not correct because they refer to different aspects of medical terminology: death conditions, nutritional issues, and general weakness do not specifically relate to the blood, which is the main focus of the suffix -emia.
