What is the immune system’s job?
Your immune system is an entire network system that functions in tandem to safeguard the body against foreign invaders like bacteria.
Your immune system is an entire network system that functions in tandem to safeguard the body against foreign invaders like bacteria, pathogens infections, viruses, and parasites that could cause serious illness, infection, or even disease.
It is comprise of white blood cells, adenoid lymph nodes, and antibodies in the thymus, spleen, and bone marrow that combat invaders.
Any problems with the immune system trigger various illnesses including allergic diseases or autoimmune diseases, as well as immune deficiencies.
Consult your doctor regarding medical-relate concerns, such as how you can improve your immune system and help you avoid illnesses like COVID-19 and other conditions which can impact your health.
Essential components that makeup our immune system
White blood cells:
White blood cells are the largest and most important component of the immune system.
It is create in the bone marrow. White blood cells fight harmful viruses and bacteria and then destroy their targets.
White blood cells are compose of components including granulocytes like neutrophils, eosinophils and monocytes, basophils, and lymphocytes.
Lymph nodes:
It is a small gland with immune cells. These cells eliminate pathogens and stop the spread to other areas of the body.
Spleen:
They store white blood cells and protect your body from foreign contaminants.
It also cleanses your blood, taking out old or damage red blood cells.
Thymus:
The small organ that lies behind the breast bone in your chest.
It is responsible for the maturation process of a particular kind of white blood cell.
It learns to recognize and keep track of an invader so that an attack can be initiate immediately after the invaders enter the cells.
Innate immunity as well as Adaptive immunity
There are two major kinds of immunity, well-known as adaptive and innate immunity.
Innate immunity is a primary define that is store genetically in your body from the time your birth, which is sometimes referred to as natural immunity.
Adaptive immunity is a third line define that must be obtained from other sources that are classifie into passive and active immunity.
Innate immunity develops before exposure to pathogens, by stopping the entry of pathogens infecting the host and is then eliminate by two processes:
Direct destruction
It is responsible for the production of chemical chemokines and cytokines to the locations of inflammation and infection which are crucial in the recruitment of cells and local inflammation.
Cytokines are powerful therapeutic agents. A malfunctioning cytokine can trigger inflammation and cause autoimmune disease.
Phagocytosis
It is a collection of proteins that recognize bacteria and kill them by taking in pathogens through the process of phagocytosis.
The phagocytic activity of the immune system’s innate response eliminates foreign substances effectively by encapsulating the disease with the host’s proteins.

The adaptive immunity system is complex. It plays a specific function when the innate immune system is not effective in removing infectious pathogens.
Acquired immunity is characteriz by the recognition of antigens or molecules against pathogens invading.
Antigens are recognized due to antibodies generated by B lymphocytes and T lymphocytes.
It is believed that the acquired immune system is an innate memory, and in the event of re-infection, and antigen is recognized, the immune response will be quicker and more powerful than the initial reaction.
What conditions impact our immune system?
A few people have a hyperreactive and weak immune response.
A disruption in the immune system can lead to illnesses such as allergic diseases or autoimmune disorders.
Allergies develop when your body reacts too strongly to an allergen and triggers an immune response.
The body releases histamine to fight allergies. The symptoms of an allergic reaction, such as mild fever, sneezing facial pain, swelling of the face, itching blocked nose, and breathlessness could influence a person’s life quality and result in discomfort if not addressed.
Antihistamine medicines like chlorpheniramine and loratadine as well as cetirizine can temporarily ease symptoms like sinusitis and allergic rhinitis.
Other allergic conditions include asthma, eczema, and skin hives, and dermatitis.
Autoimmune illness is a condition that occurs in which the body’s immune system accidentally targets health cells.
Autoimmune disorders can be common to uncommon. Some examples of autoimmune diseases include Hashimoto’s disease, thyroid systemic lupus, diabetes, and rheumatoid arthritis.
The immune system not functioning properly is called immunodeficiency. The condition can be passed on from parent to child.
There are over 100 different types of immune deficiency diseases including HIV, AIDS, and specific types of cancer.
Leukemia and myeloma can cause cells to expand in uncontrolled ways and impact the immune system.
How do we enhance the performance of the immunity system?
Your immune system has to be nurtured to function effectively.
There are several methods you can follow to increase the efficiency of your immune system.
Lifestyle changes can help boost your immune system, and thus be able to avoid many illnesses.
Here are some suggestions to follow:
- Sleep enough
- Exercise regularly
- Always be sure to take care of your hygiene
- Include fruits and vegetables in your diet
- Beware of smoking and drinking alcohol.
- Be aware of your body weight and ensure you’ve got an appropriate BMI.
- De-stress with therapy like yoga, meditation, or tai chi
- Beware of exposure to harmful substances
