White blood cells are like the military of your body. The provide a defence system against invading pathogens that could harm your body.
Lymphocytes are responsible for the production of antibodies (and memory cells for immunity). Phagocytes are able to engulf cells and break them down.

B Cells vs T Cells | B Lymphocytes vs T Lymphocytes - Adaptive Immunity - Mechanism
In this video, we're going to talk about B Cells vs T Cells. We'll explore the differences between these two types of cells, and discuss their roles in adaptive immune system.
Did you know that B Cells and T Cells are two different types of cells in the immune system? B Cells are responsible for creating antibodies, while T Cells help the body to fight off infection. We'll talk about the role each type of cell plays in the adaptive immune system, and how they work together to fight diseases.
I really appreciate you watching this video. You are more than welcome to leave a comment or ask a question, I’ll do my best to get back to you. Make sure you leave a 💯 emoji if you made it to the end of the video.

Lymphocyte migration.
This short video describes how lymphocytes migrate through lymphatics which allows them to encounter foreign antigen and stimulate an immune response. Lymphocytes, such as B cells and T cells, play a vital role for the immune system to protect our bodies from infectious disease.

The T helper cells (Th cells), also known as CD4+ cells or CD4-positive cells, are a type of T cell that play an important role in the immune system, particularly in the adaptive immune system. As their name suggests, they "help" the activity of other immune cells by releasing cytokines, small protein mediators that alter the behavior of target cells that express receptors for those cytokines. These cells help to polarize the immune response into the appropriate kind depending on the nature of the immunological insult (virus vs. extracellular bacterium vs. intracellular bacterium vs. helminth vs. fungus vs. protist). They are generally considered essential in B cell antibody class switching, breaking cross-tolerance in dendritic cells, in the activation and growth of cytotoxic T cells, and in maximizing bactericidal activity of phagocytes such as macrophages and neutrophils.
Mature Th cells express the surface protein CD4 and are referred to as CD4+ T cells. Such CD4+ T cells are generally treated as having a pre-defined role as helper T cells within the immune system. For example, when an antigen-presenting cell displays a peptide antigen on MHC class II proteins, a CD4+ cell will aid those cells through a combination of cell to cell interactions (e.g. CD40 (protein) and CD40L) and through cytokines.
