Formed elements are the cellular components of blood, including erythrocytes (red blood cells), leukocytes (white blood cells), and thrombocytes (platelets). They play crucial roles in immune defense, oxygen transport, and clotting.

Leukocytes are a type of formed element that is integral to the innate nonspecific host defenses.
There are five major types of leukocytes: neutrophils, lymphocytes, monocytes, eosinophils, and basophils.
Neutrophils are the most abundant type of white blood cell and are key players in the initial response to infection.
Monocytes differentiate into macrophages and dendritic cells which are essential for phagocytosis and antigen presentation.
Platelets, although primarily involved in clotting, can also release signaling molecules that modulate immune responses.
