Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How does immune system fight viruses?
A
Immune system guards our body and when red blood cells which are the part of our immune system detect viruses in our body they kill the antigen or viruses by antibodies.
B
Immune system guards our body and when white blood cells which are the part of our immune system detect viruses in our body they kill the antigen or viruses by antibodies.
C
Immune system guards our body and when antibiotics which are the part of our immune system detect viruses in our body they kill the antigen.
D
None of above
Explanation: 

Detailed explanation-1: -The acquired immune system, with help from the innate system, makes special proteins (called antibodies) to protect your body from a specific invader. These antibodies are developed by cells called B lymphocytes after the body has been exposed to the invader. The antibodies stay in your child’s body.

Detailed explanation-2: -They are attracted towards the infective agents, then surround and engulf them. Once inside the cell, these white cells then release chemicals that break the organism down and destroy it. Other white cells, called lymphocytes, target attacks in another way, by making antibodies.

Detailed explanation-3: -The main job of the innate immune system is to fight harmful substances and germs that enter the body, for instance through the skin or digestive system. The adaptive (specific) immune system makes antibodies and uses them to specifically fight certain germs that the body has previously come into contact with.

Detailed explanation-4: -How Does the Immune System Work? When the body senses foreign substances (called antigens), the immune system works to recognize the antigens and get rid of them. B lymphocytes are triggered to make antibodies (also called immunoglobulins). These proteins lock onto specific antigens.

Detailed explanation-5: -Leukocytes patrol the blood and tissues throughout the body in search of intruders. When they detect a foreign substance, they send out signals and launch an immune attack. These disease-fighting cells are made in the bone marrow and are stored in many different places in the body such as the tonsils and adenoids.
