The lymphatic system, for most people, is associated with the immune system to such a degree that the two systems are virtually indistinguishable. The lymphatic system is the system of vessels, cells, and organs that carries excess fluids to the bloodstream and filters pathogens from the blood.

Leukocytes protect the body against invading microorganisms and body cells with mutated DNA, and they clean up debris. Platelets are essential for the repair of blood vessels when damage to them has occurred; they also provide growth factors for healing and repair.

Innate immunity, found in all metazoans, provides immediate, non-specific defense through germline-encoded receptors, while adaptive immunity, unique to vertebrates, involves specific responses with memory. It highlights immune cells, pattern recognition receptors (PRRs), and the role of adjuvants in enhancing vaccine responses.

It highlights instances such as delayed-type hypersensitivity and contact sensitivity. It also notes that some pathogens evade antibodies by invading cells, but activated T cells can enhance macrophage activity to combat these threats.

B cells produce antibodies and mature in the bone marrow, while T cells, maturing in the thymus, include CD4+ (helper) and CD8+ (cytotoxic) cells. It outlines the activation and cloning process of B cells and TCR functionality in recognizing antigen fragments. The selection process for T cells ensures self-tolerance, with gamma/delta T cells serving as a frontline defense.
