Which side of the heart is the high-pressure side of the cardiovascular system?

Explanation:
The left side is the high-pressure side because it must push blood through the entire systemic circulation to deliver oxygen to all tissues. To accomplish this, the left ventricle generates much higher pressure, which is supported by its thick muscular wall. In contrast, the right side pumps blood to the lungs via the pulmonary circulation, which is a short, low-resistance path, so it operates at much lower pressure and has a thinner muscular wall. The other options don’t describe how pressure is generated or required in these two circuits, so they don’t fit the question as well.
