Verified step by step guidance

Understand the components of blood: Blood is composed of formed elements and plasma. Formed elements include cells and cell fragments, while plasma is the liquid portion.

Identify the formed elements of blood: The formed elements include erythrocytes (red blood cells), leukocytes (white blood cells), and platelets (thrombocytes).

Recognize the role of plasma: Plasma is the liquid component of blood that carries cells and other substances throughout the body. It is not considered a formed element.

Compare the options given: Platelets, leukocytes, and erythrocytes are all formed elements, while plasma is not.

Conclude which option is not a formed element: Based on the understanding that plasma is the liquid part of blood, it is not one of the formed elements.
