Oxygen O2 is transported in vertebrates as complexed with haemoglobin.
● Invertebrates red blood cells contain a pigment called hemoglobin which has 4 units that form complex with oxygen entered into the body.
● Thus formed complex is called oxyhaemoglobin and is transported to all parts of the body and vice versa the caring of carbon dioxide takes place.
