Immune System The Protection Against Pathogens



What is the Immune System?

The immune system keeps us safe from diseases. The reason why we are disease-free is that our immune system is strong. Whenever our immune system fails to protect us from pathogens we get down with the fever, cold etc.
Our immune system prevents viruses, bacteria and parasites to enter our body. If our immune system is weak these diseases causing bacteria and viruses easily enter into our body.

How does it work? 
The immune system encourages to produce cells that assist to kill disease-causing microorganism. Some cells do a specific task to kill a certain type of bacteria or virus. The immune system sends an alert signal to the body. The immune system takes action against the foreign body. Due to the war against the virus, our body becomes warm in fever.

Components of Immune System
The immune system is composed of various elements like antibodies, white blood cells, bone marrow spleen and proteins

How to Boost Immunity?

Healthy Food
The food we take is the great immunity booster of our body.
Green vegetables and fruits are a great source of anti-oxidants. It's also laced with vitamin C and beta carotene, which may increase the infection-fighting ability of our immune systems. Protein is a must for immunity building. We should take eggs, milk curd and other protein-rich product to increase immunity. Breastfeeding provides a lot of immunity to a young baby.

Vaccination
Weak or killed viruses are introduced in the body by vaccination. The immune system gets trained to take action against the virus in the future. Chicenpo, hepatitis polio vaccine rotavirus are some very common vaccination for kids.

Do not always rely on antibiotics
Take antibiotic only when a doctor prescribes. Antibiotics can decrease the capabilities of the immune system to kill bacteria. Antibiotics are only needed for treating certain infections caused by bacteria. Antibiotics do not work on viruses, such as those that cause colds, flu, bronchitis etc.
