Closed Circulatory System — NEET Biology
📚 Practice ConceptClosed type in which the blood is circulated through a series of vessels of varying diameters (arteries, veins and capillaries).
Assertion (A): Animals have different types of circulatory systems for transport of materials. Reason (R): In open circulatory system, blood is circulated through a series of vessels, while in closed type, blood directly bathes the cells and tissues.
View solution & NCERT explanation
Correct answer: C — If assertion is true but reason is false.
NCERT confirms different circulatory system types exist (Assertion true). However, NCERT states “open type in which the blood is pumped out of the heart and the cells and tissues are directly bathed in it and closed type in which the blood is circulated through a series of vessels.” The Reason swaps the characteristics - open type has blood bathing tissues directly, closed type uses vessels.
