Question

question 14 what are the three main formed elements in blood? a lymphocytes, monocytes, and eosinophils b iron, hemoglobin, and plasma c plasma, red blood cells, and white blood cells d erythrocytes, leukocytes, and platelets

Explanation:

The formed elements of blood are cells and cell - like structures. Erythrocytes (red blood cells), leukocytes (white blood cells), and platelets are the three main formed elements. Plasma is the liquid part of blood, not a formed element. Iron and hemoglobin are components within red blood cells, not formed elements on their own. Lymphocytes, monocytes, and eosinophils are types of leukocytes, which are part of the formed elements but not the three main categories themselves.

Answer:

D. Erythrocytes, leukocytes, and platelets
