All of the following are formed components of the blood, EXCEPT:

Red blood cells
White blood cells
Platelets
Plasma

The correct answer is: Plasma

In the context of the components of blood, red blood cells, white blood cells, and platelets are all classified as formed elements. These formed components are the cellular parts of blood that are involved in various functions such as oxygen transport, immune response, and clotting. Red blood cells (erythrocytes) are responsible for carrying oxygen from the lungs to the rest of the body and returning carbon dioxide for exhalation. White blood cells (leukocytes) play vital roles in the immune system, defending the body against infections. Platelets (thrombocytes) are critical for the clotting process, helping to prevent excessive bleeding. In contrast, plasma is not a formed component; it is the liquid portion of blood that carries the formed elements, along with nutrients, hormones, proteins, and waste products. Plasma makes up a significant part of blood volume and serves as a transport medium but does not consist of cells or cellular fragments. Thus, identifying plasma as the exception aligns with the understanding of blood components, clarifying the distinction between the formed elements and the liquid component of blood.
