Jackson usually described Mark as his blood. His parents and the other members of GOT7 found it weird but to Jackson it made sense. He would often get question if he meant Mark is his heart but no. Jackson knew what he was talking about.
See, the heart is a very useful muscle for living creatures such as animals, but what use would the heart have if there wasn't any blood to pump out to the rest of the body?
Without the blood you wouldn't survive, all organs would fail. Blood helps the body with oxygen and nutrients as well as help fighting infections. You simply cannot live without it.
And that's exactly why Jackson compared Mark to blood.
