Not true about right ventricle-
**Core Concept**
The right ventricle (RV) is a crucial component of the heart, responsible for pumping oxygen-depleted blood from the heart to the lungs for oxygenation. The RV's structure and function are distinct from those of the left ventricle, with a thinner wall and lower pressures.
**Why the Correct Answer is Right**
The correct answer will highlight a characteristic or function unique to the right ventricle, such as its thinner wall or lower pressures compared to the left ventricle. The RV's contraction is also influenced by the tricuspid valve, which allows blood to flow into the right ventricle from the right atrium.
**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect, as the right ventricle's wall thickness is actually thinner compared to the left ventricle.
**Option B:** Incorrect, as the right ventricle pumps blood under lower pressures compared to the left ventricle.
**Option C:** Incorrect, as the right ventricle's primary function is to pump blood to the lungs, not to the systemic circulation.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that the right ventricle's function is closely tied to the pulmonary circulation, and conditions affecting the pulmonary vasculature can have significant impacts on right ventricular function.
**Correct Answer: B. The right ventricle pumps blood under lower pressures compared to the left ventricle.**
