Immunity System
The immunity system is our body's ability to fight toxic. It’s a network of biological processes that protect an organism from diseases. The immunity system detects and reacts to a large type of pathogens; it develops throughout life in organisms.



It’s a type of security. We develop adaptive immunity once we are exposed to diseases or once we are insusceptible against them with vaccines. If our immune is powerful then it also protects us from several diseases including infection.

Types of Immunity System
There Are Two Type of Immunity System
1. Adaptive or Active Immunity System
2. Passive Immunity System


1. Adaptive or Active Immunity: -

Adaptive or Active Immunity It is recognized when openness to an infection life form triggers the resistant framework to create antibodies to that sickness. If a person is exposed to the disease, their immune system recognizes it and immediately produces the antibodies needed to fight it.
Dynamic invulnerability is made by our own safe framework when we are presented to a potential illness causing specialist. We are naturally exposed to these potential pathogens throughout our day - the air we breathe, the food we eat, and the things we touch. Those that do not result in disease, it is because our immune system works to neutralize them.

We are not aware of most of the functions of our immune system, we often do not think about how busy it is. But the reality is that like our heart and lungs, our immune system is also continuously working to keep us healthy. Evidence of this effort is found in the fact that our immune system produces gram antibodies every single day.

Vaccines contribute to active immunity by providing us with controlled ways to create an immune response. When a vaccine is introduced, our immune system treats it like any other risk. It works to prevent "attack" and in the process, immunological memory develops. Since vaccines are designed in such a way that they do not cause disease, in this way, vaccines provide an opportunity to "train" our immune system for future encounters.

2. Passive Immunity: -

In this, a person is given antibodies directly. It's given within the womb or through a blood product containing antibodies that are used to protect the body instantly from a specific disease. The main advantage of passive immunity is that it provides an immediate protection. But passive immunity doesn't last long within the body. It loses its result among some weeks and months.
Passive immunity may prove useful within the treatment of COVID 19. This can be done mainly in patients sick from the corona through a convent serum or plasma. Actually, antibodies develop in the blood of patients World Health Organization are cured of corona virus and this antibody can treat another infected person.

How Does It Work
There are many types of cells that either move throughout the body or reside in a particular tissue. Each cell plays a kind of unique role with different ways of identifying problems, communicating with other cells, and performing its functions. Recurrent and fatal infections occur when the immune system is less active than normal.

Infectious microbes such as viruses and bacteria release a set of signals recognized by the immune system called pathogen-associated molecular patterns. When the immunity system first recognizes these signals, it reacts to solve the problem.

If the immune system response cannot be activated when enough is needed, problems such as infection arise. Immune system dysfunction can lead to auto immune diseases, inflammatory diseases, and cancer.


Characters of Immunity System
White Blood Cells
White blood cells are called leukocytes. They flow inside the body in blood vessels and the lymphatic vessels that equal the veins and corridors.

White blood cells are on consistent watch and searching for microbes. at the point when they notice an objective, they begin to duplicate and convey messages out to various cell types to do a comparable.

Our white blood cells are hang on in better places in the body, that are alluded to as lymphoid organs. These incorporate the accompanying:-

Thymus — an organ between the lungs and just beneath the neck.
Spleen — an organ that channels the blood. It sits inside the upper left of the midsection.
Bone marrow — found in the focal point of the bones, it likewise delivers red blood cells.
Lymph nodes — little organs situated all through the body, connected by lymphatic vessels.
There Are Two Main Types of Leukocyte
1. Phagocytes
These cells encompass and absorb pathogens and break them down, effectively eating them.

There Are a Few Types

Neutrophils — these are the most widely recognized type of phagocyte and tend to attack bacteria.
Monocytes — these are the largest type and have a few jobs.
Macrophages — these patrol for pathogens and furthermore eliminate dead and biting the dust cells.
Mast cells — they have numerous jobs, including assisting with mending wounds and shield against pathogens.
2. Lymphocytes
Lymphocytes assist the body with remembering past intruders and remember them in the event that they return to attack once more.

Lymphocytes begin their life in bone marrow. Some stay in the marrow and form into B lymphocytes (B cells), others head to the thymus and become T lymphocytes (T cells).

These Two Cell Types Have Different Jobs:-
B lymphocytes — they produce antibodies and help alert the T lymphocytes.
T lymphocytes — they destroy traded off cells in the body and help alert other leukocytes.

B Lymphocytes
When B lymphocytes recognize the antigen, they begin to discharge antibodies (antigen is another way to say "antibody generators". Antibodies are unique proteins that lock on to explicit antigens.

Every B cell makes one explicit antibody. For example, one might make an antibody against the bacteria that reason pneumonia, and another might recognize the normal cold infection.

Antibodies are essential for a large group of synthetic compounds called immunoglobulins, which assume numerous parts in the invulnerable reaction:

Immunoglobulin G (IgG) — marks microbes so different cells can recognize and manage them.

IgM — is master at killing bacteria.
IgA — congregates in liquids, like tears and salivation, where it secures gateways into the body.
IgE — ensures against parasites and is additionally to blame for allergies.
IgD — stays bound to B lymphocytes, helping them to begin the resistant reaction.
Antibodies lock onto the antigen, but they don't slaughter it, just imprint it for death. The killing is the job of different cells, like phagocytes.

T Lymphocytes:- they organize the invulnerable reaction. Some speak with different cells, and some invigorate B cells to create more antibodies. Others draw in more T cells or cell-eating phagocytes.
