Red blood cells are constantly being produced in your body. Another body system cooperates with the cardiovascular system in the production of these cells. What is this system and how does it cooperate? A) Red blood cells are produced throughout your lymph glands, part of the lymphatic system.

B) Red blood cells are produced in your liver and pancreas, organs that are part of the digestive system.

C)Red blood cells are produced in the bone marrow of certain bones, bones that are a part of the skeletal system.

D) Red blood cells are produced in your lungs and then circulated through your blood vessels. This is another way the cardiovascular and respiratory systems cooperate.
