What does the word root hem/o refer to in veterinary terminology?

Heart
Blood
Liver
Kidneys

The correct answer is: Blood

In veterinary terminology, the word root "hem/o" specifically refers to blood. This root originates from the Greek word "haima," which means blood. It is commonly used in various medical terms associated with blood, such as "hemoglobin" (the protein in red blood cells that carries oxygen) and "hemorrhage" (the loss of blood). Understanding this root is essential for interpreting terms in both veterinary and medical contexts that involve blood-related conditions or procedures. The other options—heart, liver, and kidneys—are associated with different terms and roots in medical terminology and do not relate to the "hem/o" root. For example, "cardi/o" pertains to the heart, "hepat/o" refers to the liver, and "nephr/o" is used for the kidneys. Recognizing these roots can enhance comprehension of veterinary terms and facilitate communication in the field.
