Blood is a fluid connective tissue which acts as the primary medium for transportation in the human body (secondary is lymph). About 94% - 95% of the blood is made up of a fluid like substance called PLASMA (matrix of blood) which consist of proteins and has the same colour as straw (yellow to dark yellow with brown tinge) and is responsible for transport of CO2, nitrogenous waste materials, hormones, nutrients and many other substances. The remaining 5% is made of solid components ie, RBCs, WBCs and platelets. Red blood cells (red due to haemoglobin) help in transport of O2 and do not have a nucleus. White blood cells act as soldier cells protecting human body from pathogens. Whereas, platelets form networks in order to plug leaks in the blood vessels ie, BLOOD CLOTTING.
