Let me clear u, heart does not have an artery, heart is divided into four chambers, namely; right auricle, right ventricle, left ventricle and left auricle. So, what we have dat functions lyk artery is main aorta. So no artery in the heart
No blessing.the artery and vein also function .while artery carry blood away from the heart vein carry blood to the heart.
If arteries is not responsible for pumping blood..then tell me the function of the arteries.
The correct answer is:
D. Left ventricle
The left ventricle is the primary chamber responsible for pumping oxygenated blood throughout the body via the aorta. It has the thickest and most muscular walls of all heart chambers, enabling it to generate the high pressure needed for systemic circulation.
Veins (A) return blood to the heart but do not pump it.
Right auricle (B) (right atrium) receives deoxygenated blood from the body but does not pump it into systemic circulation.
Arteries (C) carry blood away from the heart, but they do not generate the pumping force themselves.
