The *heart* is the main organ of the circulatory system.
The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic).

Explanation:
Producing breast milk to satisfy a starving newborn is an arduous and energy-intensive task - about 500 calories a day. Therefore, it is important that moms a little more than normal.
