Verified step by step guidance

Identify the main function of white blood cells (WBCs) in the body, which is to protect against infections and foreign invaders.

Understand that WBCs are nucleated cells, meaning they contain a nucleus, which is a key characteristic distinguishing them from red blood cells.

Recognize that not all WBCs are granulocytes. Granulocytes are a type of WBC that includes neutrophils, eosinophils, and basophils, but there are also agranulocytes like lymphocytes and monocytes.

Acknowledge that while some WBCs have phagocytic functions, such as neutrophils and monocytes, not all WBCs are primarily phagocytic.

Clarify that WBCs do not transport oxygen; this is the primary function of red blood cells, which contain hemoglobin for oxygen transport.
