Verified step by step guidance

Begin by understanding the term 'formed elements' in the context of blood. Formed elements refer to the cellular components of blood.

Identify the main types of cells present in blood. These include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).

Differentiate between formed elements and other components of blood. Formed elements are distinct from plasma, which is the liquid portion of blood containing water, electrolytes, nutrients, hormones, and enzymes.

Recognize that plasma and serum are not considered formed elements. Plasma is the liquid component, and serum is plasma without clotting factors.

Conclude that the term 'formed elements' specifically refers to red blood cells, white blood cells, and platelets, as these are the cellular components of blood.
