Ace the NCLEX Cardiovascular Challenge 2026 – Pump Up Your Success!

The left ventricle is responsible for pumping blood to the systemic circulation. It receives oxygenated blood from the left atrium and sends it into the aorta to nourish the entire body. This high-pressure, thick-walled chamber is built to overcome systemic vascular resistance. In contrast, the right ventricle sends blood to the lungs via the pulmonary artery, a much lower-resistance circuit. So, for delivering blood to the body, the left ventricle is the correct pump.
