The suffix '-emia' is associated with which bodily substance?

The suffix '-emia' is specifically related to blood. This is derived from the Greek word "haima," which means blood. When this suffix is used in medical terminology, it usually indicates a condition that is related to the presence or concentration of a specific substance within the bloodstream. For instance, "anemia" refers to a deficiency of red blood cells or hemoglobin in the blood, while "hyperglycemia" refers to an excess of glucose in the blood.

The other answers refer to different bodily substances and conditions. For instance, fluid would be more accurately indicated with terms like "hydro-" or "-orrhea," while "tissue" is related to terms that use "tiss-" or "-plasia." Protein could be recognized in terms like "proteinuria," which involves proteins found in urine rather than blood. Therefore, the association of '-emia' with blood is what makes the first choice the correct answer.
