White blood cells “The masters of our immunity system”
We now have to live like a tongue between thirty-two teeth. No one knows where the new corona virus is. There is another powerful force that can be relied upon to protect oneself from disease, in addition to following health care practices. That is the body’s immunity system. Most people these days talk about immunity. Covid-19 severe cases are more likely to be found among those whose immune system is weakened by a non-communicable disease. When it comes to immunity, the number one thing that comes to mind is white blood cells. About one percent of all our blood cells are white blood cells. These fight infections and germs that enter the body from the outside. The average white blood cell in the human body is 4000 – 11000 per cubic millimetre, consisting of neutrophils, basophils, eosinophils, and agranulocytes (lymphocytes and monocytes).
Composition of White blood cells present in the body differ when an infection occurs and the body becomes ill. Neutrophils are the first to fight when there is an infection in the body. Eosinophils increase in response to allergens or in the fight against parasitic invasion. Basophils are rare and are active when there is inflammation.
When the white blood cell level is less than 3,500 cubic millimetres, the condition is called leukopenia. A situation like this occurs when,
In a severe bacterial infection
In a viral infection
In autoimmune disorders (autoimmune disorders)
As a side effect of medication and radiation therapy
In a bone marrow cancer
When the white blood cell level rises above 11000 per cubic millimetre of blood, it is called leucocytosis. A situation like this arises when,
When suffering from asthma
When inflammation is present
When leukemia occurs
If you are under stress
If the level of neutrophils is higher than normal, it is after a serious physical accident or trauma or an acute infection. Or rheumatoid arthritis, gout, and thyroiditis (swelling of the thyroid gland). Neutrophil levels are lower than normal in viral infections. In addition to receiving chemotherapy treatment, severe bacterial infections can affect this. Elevated eosinophil levels can cause allergies, cancer, and parasitic infections.
Eosinophils’ levels are lower than normal as a result of excessive alcohol consumption or increased cortisol levels. Cortisol is the body’s main stress hormone. This hormone plays an important role in the fight against germs that enter the body. Basophilic levels increase in conditions such as chickenpox, allergies, and leukaemia. Decreases in cancer, severe injuries, and acute infections. When there is tuberculosis, leukaemia, chronic infections, parasitic infections, the level of monocytes rises. Monocyte levels go down due to certain infections and certain cancers. Lymphocyte levels rise in viral or bacterial infections or any other inflammation. HIV / AIDS, sepsis (a deadly condition caused by an infection), chemotherapy, and steroid medications can all lower monocyte levels.
Considering all the above facts maintaining a good healthy life style is important in day-to-day life for a proper functioning immunity system.
