Which chamber pumps blood into the systemic circuit?

Explanation:
The left ventricle is the chamber that pushes blood into the systemic circuit. It receives oxygenated blood from the left atrium and, with powerful contractions, sends it into the aorta to supply the body. The systemic circuit requires high pressure to overcome overall body resistance, which is why the left ventricle has thicker muscular walls. In contrast, the right ventricle pumps blood to the lungs via the pulmonary circuit at much lower pressure, and the atria mainly serve as receiving chambers that funnel blood into the ventricles.
