The Role Of Immune System On Health

The immune system is our body's natural defense mechanism playing a crucial role in maintaining health and well-being. Your immune system is your body’s first line defense against invaders like germs. It helps protect you from getting sick and promotes healing when you’re unwell or injured. It is made up of:

          •   Various organs

           •    Cells

           •   Proteins

We wouldn't be able to combat dangerous substances that enter our bodies from the outside or dangerous alterations that take place within our bodies if we didn't have an immune system. Vaccinations are an effective way to use the immune system's memory to teach it to identify and fight particular invade.

Importance of a Balanced Immune System:

Immune system function is a prerequisite for good health. But keeping everything in balance is essential. While an overactive immune system can cause autoimmune illnesses, when the body unintentionally attacks its own tissues, an underactive immune system can result in infections and diseases.

Functions of the immune system:

The immune system's three main jobs are to:

, • Neutralize dangerous substances.

• Combat non-infectious illnesses.

• Fighting off and eliminating pathogens bacteria, viruses, parasites and fungi that cause disease.

Identifying and eliminating dangerous elements from the environment combating changes in the body that lead to disease such as cancer cells.

All of these tasks are performed by immune cells in a coordinated manner.

Working of Immune System:

It shields your body from dangerous chemicals, pathogens, and potentially detrimental cell alterations. It detects and gets rid of aberrant cells that could turn into cancer in addition to warding off infections. It keeps you healthy with much effort .When our body's immune system functions correctly, it notifies:

• Identifies the difference between cells that belong in your body and those that don’t.                               • Activates and mobilizes to eliminate pathogens that could endanger you.

• Terminates an assault when the danger has passed.
• Acquires knowledge about germs subsequent to encounter.
•Terminate with them and produces anti-tumor antibodies.
• Defends your body against future germ invasions by releasing antibodies

.

Things that make immune system healthy:

The immune system keeps your body safe by:

• Reducing the amount of damage foreign invaders can cause if they get inside.
• Eliminating intruders
• Repairing bodily injuries
• Preserving your body from being invaded by microorganisms .
• Changing to meet fresh difficulties and dangers.

                  

Major Organs of Immune System:

The following are the main immune system organs found in humans

• Bone marrow
• Thymus
• Dermal
• Nodes Lymphatic
• The  Kidney
• Digestive system organs, including the stomach, small and large intestines.

Bone marrow:

Inside the bones lies a substance called bone marrow that resembles sponge. The bloodstream carries these cells to different organs and tissues. Red bone marrow which actively produces immune system cells, is present in many birth bones. Stem cells situated in the spongy center of the bones are the source of red blood cells, plasma cells, various types of white blood cells, and other immune cells. The bone marrow creates billions of new blood cells each day, which are then released into the bloodstream. Hematopoiesis is the process by which all blood cells are produced throughout fetal development.

Thymus:

The thymus is located above the heart and behind the breastbone. One of the thymus's most important roles is to induce central tolerance. It aids in the maturation of a certain kind of white blood cell. Thymus cell lymphocytes (T cells) are specialized immune system cells that develop there. This cell's specific job is to identify and identify an intruder so that, the next time the intruder assaults, a counterattack can be launched with ease.

Lymph nodes:

Little bean-shaped tissue clusters called lymph nodes are seen along the lymphatic veins. The nodes of lymph serve as filters. To stop germs from spreading to other parts of the body, these microscopic glands filter and eliminate them. Painful, swollen lymph nodes indicate that the body is battling infections.

Spleen:

The spleen is a secondary lymphoid organ located high in the left abdominal cavity. Spleens are made to react to systemic infections, filter blood and absorb blood-borne antigens. It is in charge of numerous tasks including:

• Immune cell production to combat antigens
• Blood cell production throughout the fontal life.
• Erythrocytes or red blood cells are broken down by it.

• Among other things, it stores and degrades platelets thrombocytes, which are in charge of blood clotting.
Through lymph nodes and blood circulation, the spleen destroys bacteria and blood cells coated in antibodies. The spleen manufactures antibodies in its white pulse.

Components of immune system:

                 The two primary parts of the immune system are the innate immune system and the adaptive immune system.

Innate Immune System:

The innate immune system is the body's first line of defense. It provides a general defense against harmful germs and substances so it’s also called the non-specific immune system. And it is used to fight immune cells like:

·         Natural killer cells

·         Phagocytes

The main working of this component is to innate immune system to fight harmful substances and responds quickly often within minutes to hours after an infection begins.

Adaptive Immune System:

Antibodies against pathogens are produced by the adaptive immune system. It is used to combat certain bacteria that the body has already encountered. An "acquired" or "specific" immune response is another term for this. It consists of lymphocytes like B cells.
• T lymphocytes

         T lymphocytes eliminate diseased cells, whereas B cells create antibodies that neutralize infections. Because the adaptive immune system is memory-based the body can react to infections that it has previously encountered more effectively.

Factors That Influence Immune Health:

                There are several factors can influence the strength and balance of the immune system:

• Diet

• Excessive sweats at night

• Inexplicable weight loss

• Loss of hair

• Anywhere on your body,  redness rashes or inflammation

• Achy sore muscles

• Inexplicable fever

• Engaging in Exercise

• Rest

• Managing Stress

• Water

Things that prevent diseases:

             There are some factors that are used to prevent diseases in immune system:

·         Eat a balanced diet

·         Exercise regularly

·         Get enough sleep

·         Manage stress

·         Stay hydrated

Conclusion:

An intricate web of organs, cells and proteins called the immune system is necessary for life. That is essential for preserving health and warding off illness. If the bacterium re-enters the body, it may swiftly identify it and eliminate it. Increasing immunity can be achieved through adopting a healthy diet and exercise routine giving up alcohol and tobacco use and getting the required vaccinations. We can improve our general health and well-being by being aware of its role and taking action to support it.
