Answer:
The blood is responsible to transport food, oxygen, and waste materials in human bodies.
Blood usually consists of a fluid medium known as plasma where the cells remain suspended.
Plasma is responsible to transport food, carbon dioxide, and nitrogenous wastes in dissolved form.
However, oxygen is carried by the red blood cells.
Many other substances such as salts, are also transported by the blood.
