What is the primary function of the heart?

  • A. Filtering blood
  • B. Exchanging gases
  • C. Pumping blood throughout the body
  • D. Producing hormones
Correct Answer: C

Rationale: The main function of the heart is to pump blood throughout the body. The heart acts as a muscular pump that circulates blood, delivering oxygen and nutrients to the body's tissues and removing waste products. Option A is incorrect because blood filtration is a function of the kidneys, not the heart. Option B is incorrect as gas exchange occurs in the lungs, not the heart. Option D is also incorrect as hormone production is mainly carried out by endocrine glands, not the heart.
