Identify the target of systemic circulation

Systemic circulation delivers oxygenated blood to the body.

Analyze the role of each chamber

The right ventricle pumps blood to the lungs.
The left atrium receives oxygenated blood.
The left ventricle pumps blood to the body.

Determine the correct chamber

The left ventricle pumps blood into the aorta.
This initiates the systemic circulatory system.
Therefore, option D is correct.
