Hematology Prefix: Combining form: Suffix: Definition: Question 2 Hyperplasia Prefix: Combining form: Suffix: Definition:
The Correct Answer and Explanation is:
Question 1 – Hematology
- Prefix: None
- Combining form: Hemat/o
- Suffix: -logy
- Definition: Hematology is the study of blood and blood-related disorders.
Explanation: The word hematology derives from the Greek roots “haima” meaning blood and “logia” meaning study. The combining form hemat/o refers specifically to blood, while the suffix -logy indicates a field of study. There is no distinct prefix in this term.
In medicine, hematology focuses on the diagnosis, treatment, and prevention of diseases related to blood and blood-forming organs. This includes red and white blood cells, platelets, bone marrow, and the lymphatic system. Hematologists study conditions such as anemia, clotting disorders, hemophilia, leukemia, and lymphoma. Their work is essential in understanding how blood supports oxygen transport, immunity, and nutrient distribution throughout the body.
Question 2 – Hyperplasia
- Prefix: Hyper-
- Combining form: Hyper/
- Suffix: -plasia
- Definition: Hyperplasia refers to an increase in the number of cells in a tissue or organ, often leading to enlargement.
Explanation: The term hyperplasia comes from the Greek “hyper,” meaning excessive or above normal, and “plasis,” meaning formation or development. The prefix hyper- expresses excess, while the suffix -plasia refers to the formation or growth of cells.
Hyperplasia is not the same as hypertrophy, which involves an increase in cell size rather than number. This process can be physiological, as in the enlargement of a woman’s breasts during pregnancy, or pathological, such as the proliferation of cells in the lining of the uterus due to prolonged estrogen stimulation. Understanding hyperplasia is critical in evaluating tissue responses to stimuli and in diagnosing conditions like benign prostatic hyperplasia or endometrial hyperplasia.
