What does "Hem," "Hema," or "Hemo" refer to?

  1. Blood

  2. Breathe

  3. Clot

  4. Swallowing

The correct answer is: Blood

Hem, Hema, and Hemo are all prefixes or variations of the root word "heme," which refers to blood. This can be remembered by looking at related words such as hemoglobin, hematocrit, and hematology, which all relate to aspects of blood. Option B, "breathe," is incorrect because the word "hem" is not related to respiration in any way. Option C, "clot," can be misleading because clotting is a result of blood, not a direct reference to it. Option D, "swallowing," is also incorrect as there is no connection between the word "hem" and the act of swallowing.
