There’s no way our body could fight infection without its defense mechanism; thanks to the immune system. This is the best and natural way to fight any diseases.
The immune system is a complex system consisting of cells, tissues, and organs that work together to protect the body against diseases in order to maintain overall health. However, there are many surprising things you may not know about your body's natural defense system. Read below to know more!
Through a series of steps called the immune response, the immune system attacks various antigens (foreign substances that enter the body) to protect the body from various diseases. These antigens can be microbes such as bacteria, viruses, parasites, and fungi. Interestingly, even the tissues of other people entering the body - for example during organ transplantation - can be considered as foreign substances by your immune system causing rejection reactions.
The key to a healthy immune system is when it is able to distinguish between the body and the foreign material that enters the body. So when an unfamiliar foreign object enters the body, our system will perform a self-defense process.
Here are some facts about the human immune system that you may not know about yet :
- For the majority of healthy people, the immune system is constantly adapting and responding to new germs, be it viruses, bacteria, or parasites, every day. Continued exposure to these germs enables the immune system to continue to study germs and build up its resistance.
However, in rare cases, people who have chronic immune conditions such as primary immunity, their immune system generally cannot fight these germs to the fullest. Well, this makes them susceptible to infection.
- The gut works as a gatekeeper for the body's defense system
The largest part of the human immune system is in the digestive or intestinal tract. This section continuously distinguishes between good and bad bacteria for maintaining general health.
- How important is the spleen?
The spleen is a large and important organ of the lymphatic system. Its function is to purify the blood from viruses, bacteria, and other foreign substances in the body. Located behind the stomach and under the diaphragm, the spleen has many functions, including filtering damaged red blood cells and storing white blood cells for antibody production.
When the body is resistant to infection, the spleen will become bigger temporarily. Theoretically, humans can live without the spleen, since our immune system has many ways to protect the body from pathogens.
- Antibodies act as an army
When the body detects germs or foreign substances that trigger the immune system's response, it produces antibodies. Once the antibody is formed, it remembers the foreign substance and to make sure that it does not attack again. Understanding the function of these antibodies gives rise to vaccination methods in preventing certain diseases.
Keep in mind, in order for the immune system to function properly, remember to always wash your hands to prevent the spread of disease. Also, a healthy lifestyle is the most effective way to keep your immune system function optimally. Some of the things you can do to maintain your immune system are to get enough sleep, exercise regularly, avoiding stress and eat healthy foods
