What is the Function of the Immune System?

The immune system’s function is to protect your mind and your body from dysfunction, severe harm and injury.

Its many roles include defending you from the continuous onslaught of outside invaders, such as Chicken Pox, COVID-19, the Influenza virus, other familiar infections, some unknown.

Not only does your immune system protect you from nasty germs from the outside, such as bacteria, fungi, toxins and other harmful substances, but also bacteria and toxic substances on the inside.

Your immune system comprises various organs, cells, proteins and tissues working together in perfect synergy, consisting of many complex parts and working parts.

This post will give you a better understanding of what your immune system is, what it consists of and how it functions.

You’ll also get an insight into how it fights disease and infection to defend and protect you from harmful viruses and bacteria.

Below I have highlighted the important bits for you, just in case your schedule is tight.

Immunity Types

You can develop an Immunity to disease through the presence of antibodies in your system.

Antibodies are proteins produced by the body to neutralise or destroy toxins or disease-carrying organisms.

Antibodies are disease-specific; for example, the influenza antibody will protect a person exposed to the influenza virus but will not affect the chickenpox virus.

Active & Innate

  1. The Adaptive Immune System (acquired immunity)
  • Active Immunity develops over time and produces cells which are called antibodies that protect you from a specific invader can be short term, long term or life long. 
  • Passive Immunity is activated when you are introduced to antibodies to fight infection instead of antibodies produced by your immune system.

2. The Innate Immune System (natural immunity)

Innate immunity takes place immediately and is non-specific, both internal and external.

  • Internal Defenses
  • External Defenses

Also known as natural immunity or genetic immunity, and is lifelong.

Immune System Sub-Systems

Your lymphatic system consists of lymphatic vessels, similar to the veins and capillaries of the circulatory system.

 

1. Lymphatic System: A network of channels throughout the body carries lymphocytes to the lymphoid organs and bloodstream.

2. Complement System: Made up of numerous distinct plasma proteins.

3. Lymphoid Organs: Made up of organs such as the thymus and bone marrow, and secondary lymphatic tissues.

If our immune system becomes compromised due to a deficiency or has become weakened due to:

  • underlying health condition,
  • hormone imbalance,
  • obesity
  • anorexia
  • malnutrition
  • stress
  • depression
  • old age

You will have great difficulty fighting viruses, particularly those new to your system and more aggressive.

So, What Does the Immune System Do Exactly?

It fights disease-causing germs (pathogens) such as bacteria, viruses, parasites and fungi, and expels them from the body in varying ways.

  • It can recognise and neutralise harmful substances from the environment.
  • Can fight any disease-causing changes in the body, such as cancer cells.
  • Considerably slows down the degenerate and functionality that comes with old age.
  • A healthy immune system ensures a good measure of life force and vitality.

The Immune System can considerably slow down the degeneration of muscle and bone, resulting in old age.

So We Can All Agree?

In my opinion,t our excellent immune system is one of the major wonders of the world.

The Immune System’s function is essential to our very existence and happiness, which is a by-product of good health, it is our life force, and to me, that’s a beautiful thing.

It makes perfect sense, then, that you take the very best care of your immune system that you can in return, and of that fact, I am 100% confident you will agree.
