White Blood Cells Introduction (aka Leukocytes) | How they Work

The video explores the structure and function of white blood cells, or leukocytes, in the immune system. It compares them to red blood cells, highlighting differences in structure, lifespan, and quantity. White blood cells are unique in their ability to leave blood vessels and enter tissues through diapedesis. The video categorizes leukocytes into granular and agranular types, detailing the roles of neutrophils, eosinophils, basophils, lymphocytes, and monocytes in immune responses. It emphasizes the importance of specific and nonspecific immunity, and the role of memory cells in faster immune responses.
