The immune system is a network of cells, tissues, and organs that cooperate to defend the body against infections including viruses, bacteria, and other external invaders.
The immune system is a complex network of cells, tissues, and organs that work together to defend the body against infections, diseases, and foreign substances. Its main function is to identify and destroy any harmful invaders that enter the body, including bacteria, viruses, fungi, and parasites.
The immune system is made up of two main types of responses: innate and adaptive. The innate immune response is the body's first line of defense and involves the activation of cells and molecules that are always present in the body. The adaptive immune response, on the other hand, is activated when the innate response is not enough to eliminate the invader. It involves the production of specific antibodies and immune cells that can target and eliminate the specific pathogen.
There are many factors that can affect the immune system, including genetics, age, stress, diet, and environmental factors. Maintaining a healthy lifestyle, including eating a balanced diet, getting enough sleep and exercise, and avoiding harmful substances, can help to support a strong and effective immune system.

| Reduce Stress |
Get Enough Sleep: Sleep promotes healing and regeneration in the body, which can strengthen the immune system.
Immune
system cells are in charge of identifying and combating foreign intruders.
The
thymus, spleen, and lymph nodes are immune system organs that are in charge of
creating and storing immune system cells.
Frequent exercise: helps lower your risk of contracting the flu, the common cold, or other illnesses by helping to clear bacteria from the lungs and airways.
Take Action to Prevent Infection: Regular hand washing and avoiding contact with sick people will help lower your chance of becoming ill.
Take Supplements: Certain supplements, including probiotics, zinc, and vitamin
C, may help strengthen the immune system.
Decrease Stress: Stress can impair immunity, thus it's critical to discover
methods of stress management.
Don't smoke: Smoking can impair your immune system, so it's crucial to stop if you do.

What are Immune System Disorders
When the immune system isn't working properly, problems called immune system disorders might develop. Allergies, immunodeficiency diseases like HIV/AIDS and severe combined immunodeficiency (SCID), and autoimmune diseases like lupus and rheumatoid arthritis are examples of immune system disorders.
When the immune system unintentionally targets healthy cells, autoimmune disorders develop. Organ dysfunction, tissue damage, and inflammation may result from this.
Immunodeficiency diseases develop when the immune system is compromised and unable to fend off pathogens. Infections may become common and severe as a result.
When the immune system overreacts to soft material, such as pollen or pet dander, allergies develop. This may
result in symptoms like itching, sneezing, and swelling.
Immune System Functions
1. Pathogen recognition: The immune system recognizes foreign substances, such as bacteria and viruses, and triggers an immune response.
2. Phagocytosis: Phagocytes are specialized cells that engulf and digest foreign particles and cellular debris.
3. Antibody production: B cells produce antibodies that recognize and bind to specific antigens, such as bacteria and viruses, to help eliminate them from the body.
4. Inflammation: Inflammation is a response to infection or injury that helps to protect the body from further damage.
5. T-cell activation: T cells are specialized cells that recognize and destroy infected or abnormal cells.
6. Immune memory: The immune system remembers previous exposures to pathogens and can respond more quickly and effectively if the same pathogen is encountered again.
By Which Hormones Immune System Influence
The hormones of the endocrine system play a major role in
influencing the immune system.
Hormones such as cortisol, epinephrine, and norepinephrine are released in response to stress and can affect the immune system by suppressing the production of certain immune cells, such as T-cells and B-cells.
Additionally, hormones such as testosterone, estrogen, and progesterone can influence the immune system by modulating the production of cytokines, which are molecules that help regulate the immune response.
Finally, hormones such as thyroid hormones can affect the immune system by influencing the production of antibodies and other immune cells.
Immune System Weak Symptoms
1. Fatigue: This is a common symptom of a weakened immune system. When the body is fighting off infections, it can use up a lot of energy, leaving you feeling tired and exhausted.
2. Frequent infections: A weakened immune system can make it harder for the body to fight off infections. This can lead to more frequent and severe illnesses, such as colds, flu, and other infections.
3. Slow wound healing: When the immune system is weakened, it can take longer for wounds to heal. This is because the body is not able to fight off infection as quickly or effectively.
4. Digestive issues: A weakened immune system can lead to digestive issues, such as diarrhea, nausea, and abdominal pain.
5. Skin rashes: A weakened immune system can cause skin rashes, such as eczema or psoriasis. These rashes can be itchy and uncomfortable.
Immune System Components
White blood cells recognize and remove foreign invaders and are the body's primary line of defense against infection.
•Lymphatic System:
This system transports white blood cells-containing lymph, a clear fluid, throughout the body. It consists of a web of organs and pathways.
•Antibodies:
In reaction to an illness, the body makes these proteins to neutralize and eliminate foreign invaders.
•The complement system, made up of proteins that hunt down and destroy foreign invaders, strengthens the body's immunological response.

The body's defense against foreign invaders like bacteria, viruses, and other pathogens is provided by the immune system, a complex network of cells, tissues, and organs. The innate immune system and the adaptive immune system make up its two primary parts. The innate immune system, which includes physical barriers like the skin and chemical barriers like saliva and tears, is the body's initial line of defense against foreign intruders. Specialized cells and proteins that are part of the adaptive immune system are able to identify and react to particular foreign invaders.
