MORE IDEAS FROM Do You Know How Active and Passive Immunity Work to Keep You Healthy?
Passive immunity refers to the creation of immunity by introducing antibodies from outside the organism, such as the injection of antivenom after having been bitten by a snake.
Immunity is defined as the set of defenses, that our bodies possess, which has the role to protect us against pathogens and to fight against infections.
By active immunity, we generally understand the resistance that our immune system shows against pathogens.
By the so-called 'clonal selection', enough antibodies are built up in order to help our organism fight off colds or different diseases.
There are several immunity categories:
Much like a hundred years ago when Spanish Flu killed millions, questionable medicinal concoctions and folk remedies have surfaced across the world, claiming to boost the immune system.
Social media is super quick to spread nutritional advice, home remedies, and bizarre ideas. Some are straightforward like seeking out foods rich in Vitamin C and antioxidants, many pseudoscientists are peddling products like probiotics, cayenne pepper, and green tea as ways to protect us from the virus, which they cannot.
“Think of the immune system like the military, each part has a different role"
The first line of defense is the white blood cells, who are first to recognise pathogens and fight off infection. Lymphocytes, a specific type of white blood cell, work to allow the body to remember the invading microbes to fight them faster in future infections.
Other parts of the immune system include the bone marrow, where white blood cells are produced; lymph nodes, which produce and store infection-fighting cells throughout the body; and the spleen, which helps control and clean the amount of blood in the body.
Hypersensitivity reactions are an overreaction of the immune system to an antigen which would not normally trigger an immune response. The antigen may be something which would in most people be ignored – peanuts, for example, or it may originate from the body. In either case, the damage and clinical symptoms result from the body’s response to the substance rather than damage caused by the substance itself.
