Through blood tests we all know our blood groups—yes, we know the blood type but how much more are we really aware of?
Coming to what really makes up the blood pumped by our heart, the liquid part called plasma is made of water, salts and proteins. The solid part is composed of red blood cells, white blood cells and platelets.
Red blood cells are the mode of transport for oxygen from your lungs to your tissues and organs. White blood cells are part of our immune system and plasma triggers blood clotting to avoid blood loss in case of any mishaps.
Speaking of immunity and protection, did you know by the time we are six months old, as a defence mechanism, our body develops antibodies for our red blood cells!
Antibodies and antigens are two very important elements to understand how our blood cells work. Antibodies are proteins produced by our white blood cells to help fight against any foreign substance – antigen, which can be fungi, bacteria or virus. As soon as any antigen enters our body, our immune system goes in overdrive to manufacture antibodies.
Out of the four main blood types—A, AB, B and O, AB positive is the universal recipient while O is the universal donor. The most common blood type in the world is O, followed by A, B and then the rarest – AB.
Remember that your blood stream right now is carrying what you ate and drank over the past several months. Build a healthier blood and ward away bad cholesterol by exercising, drinking adequate water and keeping a check on your diet.
