Question

the chamber of the heart that endures the highest pressure is the
multiple choice
right atrium.
left atrium.
right ventricle.
left ventricle.
coronary sinus.

Explanation:

The left ventricle pumps oxygen - rich blood to the entire body through the aorta. It has to generate high pressure to overcome the resistance of the systemic circulation. So it endures the highest pressure among the heart chambers. The right atrium and left atrium receive blood and have lower - pressure functions. The right ventricle pumps blood to the lungs which has lower resistance compared to the systemic circulation. The coronary sinus is a venous structure, not a chamber that endures high pressure like the left ventricle.

Answer:

D. left ventricle
