Which Of The Following Is Not A Formed Element In Whole Blood?

The answer is A. albumin. Blood is composed of three classes of formed elements, which are the erythrocytes (red blood cells), leukocytes (white blood cells), and the thrombocytes (platelets). The formed elements of human blood present in a normal healthy adult are RBCs, WBCs, and platelets; however, albumin is not considered a formed element.

The red blood cells, or erythrocytes, are produced in the bone marrow and contain hemoglobin, which carries oxygen through the body. White blood cells, or leukocytes, are responsible for fighting infection and defending the body against disease. Platelets, or thrombocytes, are cell fragments responsible for the formation of blood clots. Albumin, on the other hand, is a globular protein found in the plasma that helps to maintain blood pressure.

It’s important to note that all of these elements are vital for the proper functioning of the body. Each component has its own role to play, and disruption to any one element can cause serious medical problems. Thus it is important to ensure that our blood is healthy and contains the right balance of these elements.


In conclusion, the answer to the question “Which of the following is not a formed element in whole blood?” is A. albumin. Albumin is an important protein found in the plasma, but it is not considered a formed element. All of the other elements, RBCs, WBCs, and platelets, are essential for a healthy body and must be present in the right balance.
