Step 1
Is this statement true or false?
Answer
The statement is false. The human heart is part of a double-circulatory system, which consists of two circuits: the pulmonary circuit (for oxygenating blood) and the systemic circuit (for delivering oxygenated blood to the body). Hence, it does not belong to a single-circulatory system.
