DIRECTIONS: The questions in this segment consists of two statements, one labelled as Assertion A"and the other labelled as "Reason R". You are to examine these two statements carefully and decide if the Assertion A and Reason R are individually true and if so
Correct Answer: (d) A is false but R is true.
Explanation:
The heart is not a tissue, but it is an important organ of the cardiovascular system or circulatory system, with the size of a fist.
The main function of the heart is to pump blood across the body through the blood vessels. As the main function of the cardiovascular system is transport, Oxygen from the lungs and nutrients from the digestive system are transported to cells throughout the body through blood.
