Which of the Following is NOT a Function of the Heart

Question

Which of the following is NOT a function of the heart?
A)Serves as an endocrine gland
B)Creates blood pressure
C)Keeps oxygen-poor blood separated from oxygen-rich blood
D)Maintains the acidity level of the blood

Accepted Answer

The heart's primary functions include pumping blood throughout the body, serving as an endocrine gland by releasing atrial natriuretic peptide, creating blood pressure through its pumping action, and keeping oxygen-poor blood separated from oxygen-rich blood within its chambers. It does not directly maintain the acidity level of the blood; this is primarily managed by the kidneys and lungs.
