How do the lymph and immune systems depend on the cardiovascular system? The cardiovascular system pumps lymph fluid through blood vessels.
Nerve impulses from the brain are carried to the lymph nodes by blood.
White blood cells from the lymph and immune systems travel through blood vessels.
The lymph and immune systems do not interact with the cardiovascular system.

The correct answer is option C. "White blood cells from the lymph and immune systems travel through blood vessels".

B. Mitosis is the division or replication of cells. Normally a cell goes through checkpoints, to see if there are any mutations, “bad qualities” or need for the cell, then the body will order the cell to go through apoptosis if it catches anything wrong. In cancer, however, the cells blast through those checkpoints without a care in the world, so they keep dividing and replicating like crazy!
