What is the main organ of the cardiovascular system?

Question 1 options:

the lungs


the heart


the spleen

Answers

Answer 1
it’s the heart lol. :)
Answer 2
the heart (B) should be the correct answer.
heart = cardio and blood vessels = vascular. since the cardiovascular system is responsible for pumping blood into the body and circulating it around, this seems to be the logical answer.
