Verified step by step guidance1
Identify the key terms in the problem: 'most numerous formed element in blood' and 'their function'.
Recall the types of formed elements in blood: erythrocytes (red blood cells), leukocytes (white blood cells), and thrombocytes (platelets).
Understand the primary function of each type: Erythrocytes are responsible for transporting oxygen (O₂) and carbon dioxide (CO₂), leukocytes are involved in immune response, and platelets are crucial for blood clotting.
Determine which formed element is the most numerous in blood. Erythrocytes are the most abundant, making up about 45% of blood volume.
Conclude that the most numerous formed element in blood is erythrocytes, and their primary function is to carry oxygen and carbon dioxide.
