Let’s talk about one of the most important organs that helps in preventing gems and other toxic substances entering the body or killing them. The organ is none other than our immune system. This organ is considered one of the most important one because it keeps our body healthy, fit and free from harmful conditions.
The following article tells us about the immune system and its working process.
What is Immune system?
The immune system is a complex network of cells, tissues, and organs that collaborate to protect the body from outside invaders including viruses, bacteria, parasites, and cancer cells. It is essential for the entire health and well-being of the body.
The immune system is divided into two parts: the innate immune system and the adaptive immune system.
Innate immune system
The innate immune system, which is present in all organisms, is the initial line of protection against pathogens. It is a non-specific immune response that is triggered as soon as a pathogen, such as a virus or bacteria, enters the body.
Physical and chemical barriers, as well as immune cells capable of promptly recognizing and responding to external intruders, comprise the innate immune system. The following are some of the most important components of the innate immune system:
Physical barriers: The skin and mucous membranes serve as physical barriers that keep germs out of the body.
Chemical barriers: Pathogens are destroyed by a variety of chemicals, including stomach acid and enzymes found in tears, saliva, and mucus.
Neutrophils: The most numerous form of white blood cell, neutrophils are the first to be attracted to the site of infection. Via a process known as phagocytosis, they may swiftly engulf and kill pathogens.
Macrophages: Macrophages are enormous immune cells that may engulf and kill infections while also alerting other immune cells to their existence.
Natural killer cells: These cells have the ability to recognize and destroy virus-infected and cancer cells.
Complement system: A set of proteins that may either directly kill infections or assist other immune cells in destroying them.
The innate immune system is an important component of the body’s defence against infections because it responds to pathogens immediately before the adaptive immune system has a chance to respond. It is not always enough, however, to totally remove infections and may necessitate the assistance of the adaptive immune system for a more specific response.
Adaptive immune system
The adaptive immune system is a subset of the immune system that is activated in response to a specific pathogen, such as a virus or bacterium, and is in charge of providing a tailored and long-term defence against that pathogen.
T cells and B cells are the two primary kinds of immune cells in the adaptive immune system. T cells are in charge of fighting infected cells directly, whereas B cells create antibodies, which are proteins that can attach to and kill certain infections.
When a pathogen enters the body, the innate immune system recognizes it. The pathogen is subsequently detected by the innate immune system, which notifies the adaptive immune system. The adaptive immune system then mounts a targeted response by producing T cells and B cells that are specific to the pathogen.
T and B cells may detect particular chemicals on the surface of infections known as antigens. When a T or B cell detects a specific antigen linked with a disease, it goes through a process of activation and proliferation that allows it to attack and eliminate the infection.
Crucially, the adaptive immune system includes a memory component that enables it to recall particular infections met in the past. If the same virus is met again in the future, the immune system will be able to generate a faster and more effective response.
The adaptive immune system is critical for protecting the body from a wide range of pathogens, including viruses, bacteria, and parasites. However, it can take several days to become fully activated, which is why the innate immune system is important for providing an initial defence against pathogens.
Conditions that affect immune system
A variety of illnesses and disorders can have an impact on the immune system. Some of the most frequent are as follows:
Immunodeficiency: Immunodeficiency diseases are situations in which the immune system is weakened or nonexistent, rendering people more vulnerable to infections. HIV/AIDS, primary immunodeficiency diseases, and secondary immunodeficiency disorders are a few examples.
Autoimmune diseases: Autoimmune diseases occur when the immune system erroneously assaults the body’s own tissues and cells. Rheumatoid arthritis, lupus, and multiple sclerosis are a few examples.
Allergic reactions: Allergic diseases are situations in which the immune system reacts abnormally to normally innocuous things such as pollen or specific foods. Allergic rhinitis, asthma, and food allergies are a few examples.
Immune system cancer: Immune system malignancies, such as lymphoma and leukaemia, are examples of immune system cancers.
immune -complex disorders: Immune complex diseases are situations in which the immune system forms immune complexes, which are antibodies and antigen clusters that can cause inflammation and tissue damage. Lupus and rheumatoid arthritis are two examples.
Immunotherapy-related adverse events: These are side effects that may develop as a result of immunotherapy therapies, which are intended to boost the immune system in order to fight cancer. Cytokine release syndrome and autoimmune toxicity are two examples.
Immune dysfunction caused by stress: Prolonged stress can have a deleterious influence on the immune system, increasing vulnerability to infections and other disorders.
How to boost your immune system?
There are numerous strategies to strengthen your immune system:
- Healthy diet: A well-balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats can give the body the resources it requires to maintain immunological function.
- Regular exercise: Exercising on a regular basis can help reduce stress and inflammation, which can boost immunological function. On most days of the week, aim for at least 30 minutes of moderate-intensity exercise.
- sleep:Sufficient sleep is essential for immune function because sleep allows the body to repair and replenish. Attempt to get 7-8 hours of sleep every night.
- Stress management: While chronic stress can harm the immune system, adopting healthy strategies to cope with stress, such as meditation or yoga, might be useful.
- Avoiding smoking and drinking: Smoking and excessive alcohol intake can impair the immune system and raise the risk of infections and diseases.
- Hygiene practices: Hand washing and basic hygiene habits can help reduce the spread of diseases and illnesses.
- Supplements: Some supplements, such as vitamin C, vitamin D, and zinc, may aid with immunological function. Nevertheless, before taking any supplements, it is always preferable to contact a healthcare expert.
Our body’s immune system is a crucial aspect that must be protected at all costs. Following the better practices stated above can assist enhance one’s immune system and keep one healthy.
