Verified step by step guidance

Begin by understanding the composition of blood, which consists of plasma and formed elements. Formed elements include erythrocytes (red blood cells), leukocytes (white blood cells), and platelets.

Recognize that erythrocytes are responsible for transporting oxygen and carbon dioxide throughout the body, and they make up the majority of the formed elements in blood.

Consider the function and abundance of leukocytes, which are involved in the immune response, and platelets, which are crucial for blood clotting. Both are present in much smaller quantities compared to erythrocytes.

Plasma proteins are not considered formed elements; they are part of the liquid component of blood, which includes water, electrolytes, and proteins like albumin and globulins.

Conclude that erythrocytes are indeed the most abundant formed element in blood, significantly outnumbering leukocytes and platelets.
