What is immunity?
Immunity is the ability to resist and fight different infections and diseases. The central pillar of immunity is Antigens and Antibodies, which revolves around the entire immunity mechanism. When immunity develops against a disease, the body can fight against the disease and resist the infections. The study of immunity and the ability to fight illness is called immunology. The discipline is called diagnostic immunology, which involves and studies immunity regarding various conditions.
What is an antigen?
The foreign material which enters the body through the environment, which makes the condition to develop antibodies, is called antigen. The antigen and antibody functioning becomes the main base of immunity.
What is Antibody?
Antibodies are protein substances which develop due to some antigens in the presence of plasma and reacts with antigen. The cells that produce antibodies are called immunocytes, which are affected through antigens and produce antibodies. Antibodies are developed due to viruses, bacteria, and other infections.
Types of immunity
There are two types of immunity.
- Active immunity: Active immunity means a man’s internal reactions towards an antigen, through which various antibodies develop in the body. This acquired immunity is against a specific antigen. This means antibodies are reactive towards a particular pathogen.
- Passive immunity: This immunity is developed in one person’s body by introducing the antibodies of another person’s serum into that person’s body. The immunity acquired is called passive artificial immunity.

- The human digestive tract has billions and trillions of healthy gut bacteria, which are suitable for digestion and the formation of vitamins B and K. Still, research has also shown that our gut bacteria help our immune system and keep us healthy in various ways. These gut bacteria are suitable for gastrointestinal tract immunity and allergy prevention.
- The body cannot function without the immune system. If the immune system collapses, the body may be surrounded with various diseases and conditions and ultimately face severe health consequences.
