IMMUNE SYSTEM

An organism’s immune system, which is made up of a range of biological processes, is responsible for keeping it healthy and free of disease. In addition to viruses and parasitic worms, cancer cells, and foreign particles such as wood splinters, it is capable of identifying and responding to a wide spectrum of pathogens.

Components

 

  • White blood Cells(Leucocytes)

 

Each and every leukocyte is a component of the immune mechanism, which is responsible for protecting the body against both infectious disease and invading organisms. The bone marrow contains hematopoietic stem cells, which are responsible for the production of all leukocytes.

 

  • Complement system

 

Protein produced by the immune system in reaction to the presence of an antigen, antibody is also known as immunoglobulin. In order to remove antigens from the body, antibodies recognize and bind to them in order to do so.

  • Complement system

Its capacities as a component of the body’s routine defenses against sickness. A part of the supplement structure, otherwise called the supplement course.

  • Lymphatic system

Invasion defense system: The lymphatic system is a part of the immune system that fights infection. For example, it generates and releases immune cells that monitor and then remove external invaders — such as bacteria, parasites, and fungus; these cells are called lymphocytes (white blood cells).

  • Spleen

Defends the blood from invading pathogens (the spleen contains infection-fighting white blood cells).

  • Thymus

The immune system’s major lymphoid organ, the thymus is one of these. Thymus cell lymphocytes or T cells mature in the thymus.

  • Bone marrow

Many different types of platelets can be produced by bone marrow. RBCs , platelets, and WBCs are produced from it. Marrow is responsible for the production of lymphocytes, which are essential to the body’s immune system.

  • Skin

It’s possible that this can assist inhibit the spread of germs in the body.

  • Mucous membranes

Some organs and bodily cavities have moist, inner linings. They produce chemicals like as mucus and other secretions that are effective at containing and killing bacteria.

Types of immunity:

  • Innate immunity

Immunity that is built into you from birth. It serves as the body’s initial layer of protection against disease. The skin and mucous membranes are examples of this type of defense mechanism. They prevent the body from being harmed by dangerous substances. It also contains cells and chemicals that are capable of attacking foreign substances’

  • Active immunity

When you are exposed to or vaccinated against a foreign chemical, your body develops active immunity, which is also known as adaptive immunity. In general, active immunity lasts for quite some time. It can last for the rest of your life in many cases.

  • Passive immunity

what happens in the absence of your own immune system’s production of disease-specific antibodies? Babies receive antibodies from their mothers, for example. Passive immunity can be obtained through the use of blood products containing antibodies. As soon as you get this form of immunity, you are protected. However, it is merely temporary in nature, lasting only a few weeks or months.

Disorders of immune system.

• Severe immunodeficiency syndrome (SCID).

Immune deficits that are only temporary in nature.

The sickness of autoimmunity

• Diabetic type 1.

Rheumatoid arthritis and lupus are two common autoimmune diseases.

What are the benefits of a strong immune system?

The advantages of having a robust immune system can be subtle. Benefits include:

Fighting pathogens, fighting germs and viruses, and fighting foreign objects. It also aids in the prevention of infections and sickness.
