  1. no. The blood will be replenished but not from the heart.  Blood cells develop in the bone marrow.  The bone marrow is constantly replenishing blood cells due to bleeding and cells that get old (most blood cells only last 3-4 months)


  2. Nope just moves it around, blood cells are created in bone marrow.
