The facts about your immune system!
Immunity is our ability to fight and resist pathogens and toxins. The word immunity itself originated from the Latin word ‘‘immunis’’, which means "exempt''. Our ability to exempt these annoying germs lies in the several components of the immune system that are harmoniously orchestrating such defence.
The environment around us is heavily populated with many organisms that can challenge our health and wellbeing constantly. Our everyday surroundings contain literally millions of pathogens and other molecules that can make us fall ill easily on every encounter. Pathogens, like viruses and bacteria, are lurking around us all the time and if left unhampered they can enter our systems, damage our different cells and tissues then eventually destroy organs and spread diseases. These microscopic bugs, although insignificant in size compared to us, but their effect on our existence is highly significant and can be detrimental.
So how do we in general stay fit and keep those bugs at bay? The main reason lies in our highly developed defence system that is capable of recognising and neutralizing those pathogens swiftly and promptly. Amazingly, this happens in our body on daily bases without us feeling or sensing a thing of such battles. Our body recruits special cells and molecules to identify, attack, and restrain any foreign invasion. Collectively; these cells comprise a complicated protective system that is called ‘the immune system’. Our immune system comprises different organs, cells and chemicals like the bone marrow, lymphatic nodes, spleen, thymus, white blood cells, antibodies, complement system and hormones. The ability of our immune system to resist any attack by any foreign particle is coined ‘immunity’. The immune system produce antibodies to identify special structures on foreign objects called ‘antigens’ and neutralise them. Any impairment to the different parts of the immune system can be damaging and life-threatening.
