Heart is the organ A.
Heart pumps a liquid that is denoted by B, and it is blood.
Blood supplies oxygen and nutrients.
These two are C and D, which are called useful substances.
The color of the liquid B is red because of the presence of RBC red blood corpuscles.
The waste is carbon Dioxide, which is removed by blood from the cells.
