Hello everyone..!

I hope you are doing great and safe. I am here again to discuss about health care. Today we have a hot topic.

Almighty create a best system in our body to fight against disaese called immune system. We are human, we always pray for different diseases. Each disaese cause is different on the base of its symptoms and reaction on our body.

Some disease are caused by insect, some disaese caused viruses like Covid-19. Some disease caused by bacteria like dahrrea. So our body deal with each infection with different manners. Lets move to the topic and how immune system dose work ? And how we can make it more strong?

What is immune system

This is naturally system to fight against different diseases. When foreign particals or antigen (virus or bacteria) try to inter into our body. Our body have a security system to detect foreign disease causing agents and kill them. This system also works as security guard. Continuously screening blood vessels, organ , tissues to detect foreign particals and kill them before causing any infection.

Components of immune system

• Dendritic cells (present in all body parts and detect antigen or work for signaling in the body)

• Phygocytes (engulf antigen and kill it completely)

• T lymphocytes (directly kill foreign antigen and produce cytokines)

• B cells (produce antibodies which is highly specific to antigen)

• Memory T cells (make memory of specific antigen which is already intered into the body and if in future in come again out immune system detect it easily and kill fast)

Types

Innate immunity: when foreign particals or antigen inter into the body phygocytes engulf it and then kill it by endocytosis process. Here memory cells are not produce and it is just detection and kill of antigen.

Adaptive immunity: This immunity is adaptive by cell. We artificially adopt it. Like we vaccination. We vaccinated before we get infection.

This is two types

Active immunity (when we get vaccine to secure ourself for future intrection called active immunity)

Passive immunity (when get antibody to protect our body for future viral infection)

How immune system dose works ?

Our immune system controls by lecocytes (white blood cells) they are present in blood stream and blood vessels. 1 microliter of blood contains 4ooo-11000 leukocytes.

Leukocytes continuously screening blood, tissue and organ for suspicious activity in the body. So direction depends upon the antigen composition and structure. Some moleculer traces are present on the surface of foreign pathogens. Some antigen detect by the detection of carbohydrates in the surface of pathogens. Detection take 1 minute to induce response to kill the foreign pathogen or antigen.

• Phagocytes are highly diverse in human body. Trigger immune response when foreign antigen is detected. They send microphage cell and send signal through dendritic cells to detect foreign particals and uptake it and kill it. Then they send signal to higher level of immune system T lymphocytes.

• T lymphocytes go for searching for infected body parts and kill the infected cells. Than B cells and T cells use the information gather from forgin antigen and make antibodies

• B cell is responsible for production of antibodies. Large amount of antibodies produce and screated into the blood streaming. They continuously producing antibodies untill body is out of risk.

• Than memory T cells save the information of this particular antigen and if this same antigen inter again into the body our body would have information about this particular antigen. So the detection and action would be fast and kill it immediately.

What are autoimmune disaese?

Actually sometimes our immune system fail to determine the difference of body cells or antigen. Our immune system take a body cell and consider it foreign antigen and start producing antibodies again it. Which cause autoimmune disaese.eg juvenile (type 1) diabetes.

7 ways to boost immune system naturally.

Enough sleep

By getting enough sleep make our immune system strong. If we take complete sleeping hours than our immune system would be strong. When we are sleeping all physical activities are stoped and our body in relax form so our immune system become more active and kill the waste particals from our body and make our immune system more active to fight against any disease. So 8 hours is must for enough sleep.

Those who do not sleep properly they have weak immune system and Bigger Chance to infection.

Take more vitamin C

Vitamin C is antioxidant and antiflammantory which protect us from different free radicals and infection. It also protect us from lungs cancer. It make our immune system more strong. Vitamin C found in citrus food and red pepper is beat source of vitamin C.

Avoid Sugar

To eat more sweet containing foods weak our immune system and our immune fail to fight against different diseases. It increase high blood sugar level. So keep yourself away from high sugar containing foods and sweets. In results you can save yourself teeth from teeth diseases and your injuries would recover soon if you use less sugar in your diet. It would strong your immune system and infection hazard would be less.

Stay hydrated

Drink more and more water according to your need. So it keep yourself from dehydration. When we use less water we caught by dehydration. Dehydration lead to make our immune system weak. So when we drink more water than our immune cells get stronger as well as work more effectively. So when you go outside keep a water bottle with yourself. When you feel thirsty drink water on time.

Take proper diet

To take good diet, it make our body stronger physically also make our immune system stronger. So we should take all vitamin which are necessary for growth and which make our immune system more stronger. So skip junk food. Focus on natural foods.

Wash your hands regularly

Thousand if microbes present on our hands. Hands are only body parts which do all works. So we touch different things which contains thousand of microbes which can cause disease by touching hand on mouth and nose. So if you keep cleaning your hands regularly you get low risk of disaese. And your immune system would get time to make itself more perfect. That's the reason in Covid-19 precautions to clean your hand again and again so the risk of infection decrease.

Wear mask

Wear mask decrease the Chance of infection at great extent. When we are in mob or polluted areas. Automobiles smoke cause different diseases like lungs cancer etc. So cancer is unprogrammed death of cell. So our immune system fail to control it. So wear mask can protect you from different infection and disaese. But when you are at home or office alone no need to wear it. Because over use of mask also lead weak out immune system.

Summary

Clearly you can see if you have strong immune system then you are a healthy and minor viruses cannot effects you. As you saw that in Young generation the ratio of covid-19 infection was less than babies and old men and women. A young man have very strong immune system. But with passage of time and some Environmental factor weak our immune system.

Almighty make a best protection system again disaese. So it is depends upon us how we care about ourselves. We need precautions to save yourself from different diseases by making immune system more stronger. So do excersize regularly and take food diet which have all vitamin espically vitamin C. It is so necessary. So take care of yourself. Adopt such a environment where no risk of infection and pollution.

Source of information

I got nothing from google. This was our last time lecture on immunity. We have a subject name immunity, so my sir! Tells us in detail about immune system and how it works. So i got idea to share with you. Because it was very important topic to tell for welfare of human.

Thanks for reading :)
