Answer:
Infants are able to regulate cardiac output by changing the stroke volume to a greater extent than presumed, at least when cardiac output is influenced by changes in the mean airway pressure.
Explanation:
Cell replication is meant to be a very regulated process. Messages are sent to the cell, telling it when to duplicate and when not to. When cells divide according to their natural plan, then there are no problems. However, when cells either do not receive those messages or misinterpret them, they can divide too fast and without pause. These renegade cells are what we call cancer cells.
