Verified step by step guidance

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: The formed elements of blood include erythrocytes (red blood cells), leukocytes (white blood cells), and platelets (thrombocytes). These are the cellular components responsible for various functions such as oxygen transport, immune response, and blood clotting.

Differentiate between plasma and formed elements: Plasma contains water, electrolytes, nutrients, and proteins like albumin, globulin, and fibrinogen. These are not considered formed elements as they are part of the liquid portion of blood.

Recognize the role of formed elements: Erythrocytes carry oxygen, leukocytes are involved in immune defense, and platelets are crucial for blood clotting. These functions are essential for maintaining homeostasis and responding to physiological challenges.

Review the options given: Compare the options provided in the problem with the definition of formed elements. Erythrocytes, leukocytes, and platelets match the description of formed elements, while the other options refer to components of plasma or other non-cellular elements.
