It is a red coloured fluid that flows in vessels and is responsible for the transportation of different useful and harmful substances.Blood forms about 8-10% of the body weight of a vertebrate.It is saltish in taste, slightly alkaline in nature, heavier than water and viscous sticky fluid. Blood is bright red when oxygenated and dark red when deoxygenated.
The human heart is about the size of a clenched fist. It is a muscular organ that rhythmically contracts to force blood around the body of an organism. The circulation of blood is initiated by the heart which lies in between the lungs and slightly towards the left side. It is formed of four chambers.
