Difference Between Active and Passive Immunity

What is Immunity?

Difference Between Active and Passive Immunity: Immunity is a state of being resistant to a particular infection or disease. This can be due to natural or artificial means. Immunization is a form of artificial immunity that achieved through vaccination.

What Does the Immune System do?

The immune system is a network of cells, tissues, and organs that work together to protect the body from infection. It recognize and attack viruses, bacteria, and other organisms that can cause harm. The immune system also helps to remove damaged cells and substances from the body.

Active Immunity

One way the body defends itself against disease is through active immunity. Active immunity achieved when the body produces its own antibodies in response to a disease or infection. The antibodies attach to the invading cells and destroy them. Active immunity can be either naturally-occurring or artificially-induced.

Passive Immunity

is the transfer of antibodies from one person to another, either through serum transfusion or through the placenta during pregnancy.

Passive immunity is the transfer of antibodies from one person to another, either through serum transfusion or through the placenta during pregnancy. It is a type of immunity that obtained when antibodies from a foreign source introduced into the body. It is usually short-term, as the body eventually eliminates the antibodies. Passive immunity can be obtained through the transfusion of blood or serum from an immune donor, or through the transfer of antibodies from a pregnant woman to her fetus.

Difference Between Active and Passive Immunity

There are two types of immunity- active and passive immunity. Active immunity acquired when a person exposed to a disease and their body produces immunity to it. Passive immunity, on the other hand, is when a person is given immunity from someone else. This done through a vaccine or through a blood transfusion.

Examples of Active Immunity

An example of active immunity is when a person vaccinated against the flu. The vaccine causes the person’s body to produce antibodies to the flu virus. If the person is then exposed to the flu virus, they will have a better chance of fighting off the infection because their body will already have some immunity to the virus.

Examples of Passive Immunity

Passive immunity conferred upon an individual by the transfer of antibodies from another individual. Passive immunity conferred upon an individual either through the injection of preformed antibodies or through the transfer of immunity-producing cells called lymphocytes.

Some Interesting Facts of the Immune System

• The immune system is a collection of organs, tissues, and cells that work together to protect the body from infection.
• The immune system divided into two parts: the innate immune system and the adaptive immune system.
• The innate immune system is the first line of defense against infection. It consists of a variety of cells and organs that are always ready to respond to infection.
• The adaptive immune system is the second line of defense against infection. It consists of a variety of cells that activated when the body gets infected. These cells mount a response to the infection and help to clear it from the body.

Acquired or Adaptive Immunity

• The acquired or adaptive immune system is a complex network of cells and organs that defends the body against infection. The system composed of two main parts: the humoral immune system and the cell-mediated immune system.
• The humoral immune system is responsible for producing antibodies that recognize and neutralize invading pathogens. The cell-mediated immune system is responsible for destroying infected cells and pathogens by recruiting and activating special immune cells called T cells and killer cells.
• The acquired or adaptive immune system is a complex network of cells and organs that defends the body against infection.

The system composed of two main parts:

• the humoral immune system, which produces antibodies that recognize and neutralize invading pathogens
• the cell-mediated immune system, which destroys infected cells and pathogens by recruiting and activating special immune cells called T cells and killer cells.
