Question

Treatment of snake’s bite by providing antivenom is an example of
A. Artificially acquired active immunity
B. Artificially acquired passive immunity
C. Natural acquired passive immunity
D. Specific natural immunity

Answer 1

Hint: The body needs to protect itself from any foreign particle from harming it. It will get triggered when it will sense some problem. It can send its soldiers (antibodies) to fight against them. From our birth, we get this immunity from our mother and it slowly develops during a lifetime.

Complete answer:
The snake’s venom can be very poisonous and fatal for the beings. As soon as it enters the body, it can affect any part of the body depending on the type of venom. For example- cobra’s venom usually affects the neural system.
The immunity is a defence system in our body to fight the foreign organisms that enter to harm us. This gets activated when it senses some foreign particle in the system.

The defence mechanism sends antibodies to fight with those foreign organisms to make them exit our body system. Immunity can be active or passive. Active immunity is long-lasting and is developed with the encounter to pathogens. Passive immunity develops for a short time in the body to fight pathogens instantly.
Snake venom can be countered with the anti-venom as it has antibodies which will fight the venoms antigens or pathogens.

> Option A: Artificial required active immunity: Antivenom gives artificial immunity but is not active. As the antibodies are given to fight for venom only for that particular instance.

> Option B: Artificial required passive immunity: The anti-venom provides passive immunity as it is for the short time to prevent the spread of the venom. It is artificial as it's given and prepared from outside.

> Option C: Natural acquired passive immunity: It is not a natural immunity but an artificial one. It is not acquired rather artificially inserted.

> Option D: Specific natural immunity: Antivenom does not provide natural immunity, it gives passive immunity.

Hence, the correct answer is option (B).

Note: Immune system is the complex mechanism powered by blood and lymph. We should maintain a good immune system to live long. The immune system includes WBC’s, spleen, thymus, bone marrow and lymph.
