Our Immune System | Work, Parts, Boost, And More – healthytalk8


So today we talk about how we need them a lot in this tremendous time, which means immunity. so let’s fight against covid and talk about the immune system.

Our immune system normally adjusts to our environment.

For example, when your body encounters something that causes harm, then your immune system becomes aware and gets ready for that.

And that is the immune system that protects us from dangerous diseases like cancer diabetes, TB, etc. without an immune system we can’t stand in today’s times.

So say thank you to your immune system for keeping you healthy, but some people have low immunity – we will talk about this further.

1. Immune System

Our immune system is like a protection shield that protects us from viruses, and diseases caused by tiny invaders.

Immunity helps to protect us against unknown diseases which are caused by invaders called pathogens such as viruses, bacteria, and parasites.

And our immune system is spread throughout the body and involves many essential parts, cells, tissues, and antibodies, which all work together to kill these bad bacteria.

If the immune system encounters a pathogen, for instance, a bacterium, virus, or parasite, this reaction is an immune response.

2. How Does The Immune System Work?

When invaders such as viruses, bacteria, and parasites enter our body, our immune system recognizes it as a foreign invader and attacks it.

But how immune system recognize that is bad bacteria or viruses?

And throughout the body, cells fighting disease are stored in the immune bank and whenever that virus arrives, the cells are ready to fight.

How Immune system recognizes that this is a bad bacteria?

Antibodies are used here, which is very essential (like a guard) and are designed for the specific binding site that only connects with the antigens that have their structures on their binding sites and only allows the good bacteria to enter, and grab bad bacteria to kill.

To understand this in a good way, see the diagram given below where antigens are bad, and antibodies are grabbing them.

And antibodies are in the number of millions that are produced by specialized white blood cells called B lymphocytes, or (B cells).

3. Covid, and Immune System Connection

At this time of Covid, our immunity should remain strong. because covid first attacks our immune system.

Our doctors are treating the coronavirus patient not everyone can recover from the treatment.

Because it depends on our immune system and how strong our system is to fight coronavirus.

Read: Why does the coronavirus attack only on our immune system?

Because the Ace2 receptor in our lungs boundary corresponds to the spike protein above the coronavirus that is why the covid attacks only on our lungs, not in the brain, or skin.

The spike of coronavirus is key and the Ace2 receptor is a lock.

4. Essential Parts of the Immune System

There are 7 parts of the immune system, but here I briefly explain to you 2 main parts of the immune system, which would be very useful even in Covid. include:


Antibodies (like a guard), and many different types of antibodies have different-different binding sites, with this, they capture and destroy foreign invaders called antigens, which enter the body.

The antibodies then mark these antigens for destruction. there are many cells, proteins, and chemicals involved in this attack.

White blood cell

WBC plays an essential role in your immune system.

They are made in your bone marrow and are part of the lymphatic system.

White blood cells roam our whole body through our blood and tissue and find foreign invaders like:

  • Viruses
  • fungi
  • parasites

NOTE: In the case of coronavirus, the same thing happens, when antibodies catch the coronavirus, they also need someplace to throw it.

In such a situation, WBC comes in handy. he goes to those places that have antibodies and inserts the coronavirus inside himself with antibodies.

Other parts

  • Lymphatic system: Small glands positioned throughout the body, linked by lymphatic vessels.
  • Spleen: An organ that filters the blood. it sits in the upper left of the abdomen.
  • Bone marrow: Bone marrow is found in the centre of most bones and has many blood vessels. and also produce red blood cells.
  • Thymus: A gland between the lungs and just below the neck.
  • Complement system: This is a part of the immune system that enhances the ability of antibodies, and others cells.

5. Immune System Cells

The cells of the immune system are classified distinctly such as:

  • Lymphocytes (T-cells, B-cells, and NK cells)
  • neutrophils
  • monocytes, and macrophages these are all types of WBC.

Lymphocytes are white blood cells that are also one of the body’s main types of immune cells. 

There are 3 main parts of lymphocytes include:


T cells are like soldiers who search out and destroy the targeted invaders. T-cells are also known as “killer T cells” – that they can kill viruses, as well as cancer cells.

T-cells are born from hematopoietic stem cells found in the bone marrow. then, developing T cells migrate to the thymus gland to mature.


This is also a type of WBC of the lymphocyte subtype. these function in the humoral immunity component of the adaptive immune system.

B-cells fight against bacteria, and viruses by creating Y-shaped antibodies that are specific to each pathogen.

It can lock on the surface of invading cells. an mark it for destruction by other immune cells.


NK cells are also known as “Natural killer cells”. NK cells provide rapid responses to virus-infected cells and other intracellular pathogens.

However, they can recognize and kill stressed cells in the absence of antibodies.

6. How To Boost Immunity?

There are many ways to boost immunity especially, in this Covid situation which should be our priority to strengthen our immunity which is a wise thing.


This is the best way to boost immunity and has no side effects because it is all-natural.

  • Yoga: It is the best and my first option to boost immunity naturally, many Patanjali evidence says that anulom vilom, kapal bhati, child pose, and surya namaskar are some of the yoga that will help you in increasing immunity as well as reducing Allergy.
  • Turmeric milk: I also consume turmeric milk daily before going to bed at night. due to which I have shown a great difference in my immunity.
  • Well-balanced meal: Fast food, has been linked to many negative health effects. Eating many streets food may also weaken your immunity

Essential vitamins/supplement

  • Vitamin D: Some research shows that having healthy levels of vitamin D can help keep your immune system healthy and may protect against respiratory illnesses in general.
  • Vitamin B6: Rich foods like – chicken, salmon, and tuna. vitamin B6 is also found in green vegetables such as kale, microgreens, cabbage, etc.
  • Vitamin E: is a powerful antioxidant that helps the body fight off infection. Foods rich in vitamin E include nuts, seeds, and spinach.

Notice: Boost your immunity naturally as much as possible, do not depend as much on the supplement, and only take it when you realize that food is not enough to fulfill your vitamin bank.

Down Line

Our Immunity helps to protect us against unknown diseases which are caused by invaders called pathogens such as viruses, bacteria, and parasites.

White blood cells roam our whole body through our blood and tissue and find foreign invaders like viruses, fungi, and parasites, and when they find them they make an immune attack.
