Blood is a fluid connective tissue. It serves to transport digested food from the small intestine and oxygen from the lungs to every cell of the body. It also collects waste material from the cells and transports it to places where it gets filtered out. Water which gets reabsorbed from the large intestine is redistributed in the body via blood. Blood also serves to protect us against any foreign invasion by germs or microbes. Apart from these, blood also helps in maintaining the normal body temperature of an individual.
