Answer:
Lungs supply oxygen carried by blood to cells of the body. The cells which are responsible for the transportation of oxygen is hemoglobin. When oxygen rich hemoglobin reaches a cell so the oxygen is unloaded and carbondioxide which is produced as a waste product is loaded in hemoglobin. Again this hemoglobin goes to the lungs and dispose carbondioxide there and repeat the process again.

Answer:
Explanation:
Long-term Self-Renewal: Stem cells are capable of division while remaining unspecialized.
Differentiation
: Stem cells can divide asymmetrically, where one stem cell divides into two cells that have different cellular fates. 
Induced Pluripotency
: Stem cells that have been artificially created from specialized cells are called induced pluripotent stem cells. 
Considerations
: Due to their unspecialized nature, stem cells have a large research potential. The most pluripotent stem cells derive from the human embryo.
