What is the immune system:
A complex network of cells, tissues, organs, and structures that help the body fight infections and other diseases. Immune systems include white blood cells and organs and tissues of the lymph system, such as the thymus, spleen, tonsils, lymph nodes, lymph vessels, and bone marrow.
Outside of your body, foreign invaders are waiting for opportunities to spread. Bacteria, viruses, bacteria and fungi can all thrive inside your body - usually at your own expense. It keeps your immune system away from your healthy cells, protecting you from infections. Trying to block attackers. If they do not do so, your immune system attacks the invaders and spreads the disease. To do this, your body uses various cells and a network of all connected organs to prevent threats.
Immune Strategies:
Strategies for a healthy immune system include:
Regular exercise - Experts recommend at least 150 minutes of moderate exercise per week.
Eat a healthy, nutritious diet full of fruits and vegetables - Use the Plate method to find the components and types of healthy foods that most feed your army.
Keeping a healthy weight - Set a BMI of 25 or less. The best way to lose weight is through exercise and a healthy, nutritious diet.
Getting quality sleep - Set a schedule and pattern for sleep, and exercise cleanliness.
Reducing stress and developing positive coping strategies - Include activities in your daily life that help you deal with stress, such as hobbies with people you love, going out, engaging in regular meditation, exercise, play art or other hobbies.
Quitting smoking - If you smoke, you can get support to help you quit.
Drink only moderate alcohol, if not - Limit the amount of alcohol you keep in the house or set the amount of glasses / bottles you drink.
Taking steps to prevent infection - This includes regular hand washing and social isolation.
Function of immune system?
The immune system works to prevent and slow down the local production or systematic distribution of bacteria, viruses, fungi, and protozoa. In addition, it should accomplish this function without over-inflammation or autoimmunity development. The immune system has four main components:
1.
The immune system (humoral or B cell immunity) is controlled by B lymphocytes found in bone marrow and plasma cells (cells that produce different antibodies), which release antibodies (immunoglobulins) into secretions, plasma, and interstitial. Antibodies work to stimulate and promote biological phagocytosis, reduce toxins, and lyse pathogens (with the help of ingredients).
2.
Cell-mediated immunity (T cell immunity) is linked to thymus-derived T lymphocytes (i.e., CD4 and CD8 T cells) that act on antigen-presenting cells (e.g., dendritic cells, macrophages). ) and antigens. Although T cells do not produce immunoglobulin, CD4 T cells are needed for B cells to function properly. CD4 T cells also produce cytokines that activate phagocytes to release viruses within cells. CD8 T cells divide the infected cells.
3.
The phagocyte system contains macrophages of tissue and dendritic cells, as well as blood monocytes and neutrophils. Responding to certain signals, phagocytes swallow and kill invasive microorganisms. Dendritic cells act as antigen-presenting cells in T cells.
4.
The filling system works with antibodies and residues of the immune system to help clear microbial infections both directly (intermediate catalysis) and indirectly (phagocyte cell recruitment, opsonization of microbes).
