What are the 4 immune system components?

The cells of the immune system can be categorized as lymphocytes (T-cells, B-cells and NK cells), neutrophils, and monocytes/macrophages. These are all types of white blood cells. The major proteins of the immune system are predominantly signaling proteins (often called cytokines), antibodies, and complement proteins.

What are the 4 characteristics of the innate immune response?

The innate immune system includes physical and anatomical barriers as well as effector cells, antimicrobial peptides, soluble mediators, and cell receptors (Table 1).

Can the acquired immune system be understood without the innate one?

The acquired immune system can’t be understood without the innate one. As various sources point out, it’s the cells of the innate system that process the antigens (substances of viruses and bacteria) and present them to the lymphocytes. It’s all so that they act accordingly.

How does the immune system react to foreign molecules?
