Understand the components of blood: Blood is composed of plasma and formed elements. Plasma is the liquid portion, while formed elements are the cellular components.
Identify the formed elements: Formed elements of blood include erythrocytes (red blood cells), leukocytes (white blood cells), and platelets (thrombocytes).
Differentiate between plasma and formed elements: Plasma contains water, electrolytes, nutrients, and proteins like albumin, globulin, and fibrinogen, but these are not considered formed elements.
Recognize the role of formed elements: Erythrocytes are responsible for oxygen transport, leukocytes are involved in immune response, and platelets are crucial for blood clotting.
Conclude with the correct answer: Based on the definitions and roles, erythrocytes, leukocytes, and platelets are the formed elements of blood.
