Verified step by step guidance

Understand the context: Blood is composed of various components, including plasma and formed elements. Formed elements include erythrocytes, leukocytes, and thrombocytes.

Identify the role of each component: Erythrocytes (red blood cells) are responsible for carrying oxygen, leukocytes (white blood cells) are involved in immune response, and thrombocytes (platelets) are involved in blood clotting.

Recognize common diagram labeling: In diagrams, erythrocytes are often labeled as '1' due to their abundance and primary role in oxygen transport.

Differentiate between the options: Plasma cells are not typically considered a primary formed element in blood; they are a type of white blood cell involved in antibody production.

Conclude based on typical labeling conventions: Given the options and typical diagram labeling, '1' is most likely to represent erythrocytes, which are the most numerous and easily identifiable formed element in blood diagrams.
