PATHOLOGY

Detailed explanation-1: -Immunity to a disease is achieved through the presence of antibodies to that disease in a person’s system. Antibodies are proteins produced by the body to neutralize or destroy toxins or disease-carrying organisms.

Detailed explanation-2: -In most cases, if you are immune to something, it has no effect on you-for example, you might be immune to a disease or to criticism. If you are immune from something, it cannot reach you-for example, you might be immune from prosecution in a plea bargain.

Detailed explanation-3: -The immune system protects the body from possibly harmful substances by recognizing and responding to antigens. Antigens are substances (usually proteins) on the surface of cells, viruses, fungi, or bacteria.

Detailed explanation-4: -A healthy immune system can defeat invading disease-causing germs (or pathogens), such as bacteria, viruses, parasites-as well as cancer cells-while protecting healthy tissue. Understanding how the immune system works and how we can help protect our bodies is essential to the fight against the COVID-19 pandemic.

Detailed explanation-5: -Immunity is the ability of the body to defend itself against disease-causing organisms. Everyday our body comes in contact with several pathogens, but only a few results into diseases. The reason is, our body has the ability to release antibodies against these pathogens and protects the body against diseases.
