What are the types of immunity offered by the human immune system?
The human body is a classic example of a complicated multicellular organism. Right from the circulatory system to the excretory system, the human body has different kinds of systems that carry out several life processes in it. But have you ever wondered what protects our body from the harmful effects of the pathogens around us? The human immune system is the one responsible for this job. It is composed of different structures which produce diverse antigens like CD20 antibody, that help in protecting the body against these pathogens.
According to the researches, there are two types of immunity present in the human body. One we tend to get from the mother’s womb, and the other type is acquired throughout our life. Here is a brief description of both types of immunity present in our body for reference:
- The innate immunity
Innate immunity refers to the generic responses of the body cells, which are non-specific and are present in the human body from birth. Right after the emergence of the antigens in the body, the body provides the first line of defense to combat the harmful effects of the pathogen.
This response is generally non-specific in nature and is visible right after birth. These responses are activated by the chemical properties of the antigens entering the body. The organs that take part in the innate immunity include skin, gastrointestinal tract, respiratory pathways, and the lungs, nasopharynx, eyes, etc.t Don't use plagiarised sources.Get your custom essay just from $11/page
- The acquired immunity
The subsystem of the human immune system helps the body to develop the second line of defense over time. As a result, the body tends to develop an advanced level of immunity, which is termed as the acquired immunity. The acquired immune responses help the memory cells to store the pathological responses accordingly from time to time.
As a result of such memories of the responses, the body can provide an advanced level of immunity in the future. The different systems involved in the acquired immunity help the body to synthesis different kinds of antibodies like CD20 antibody, thereby providing the ultimate security to the body. This type if mainly defined by the presence of the lymphocytes, B and T cells, and other associated organs. The T cells are the effector cells that can directly destroy the tumor cells present in the body.
On the other hand, the B cells are the ones responsible for the production of antibodies in response to the presence of the antigens in the body. These two systems work in close relation to provide the ultimate protection to the internal systems of the body. To know more about these kinds of systems, make sure to consult your doctor or any other specialist available in the market.
