Question

I am a chamber of your heart and blood rushes enters me through a valve at the left atrium. I contract and push blood into the Aorta. What am I?

Answer 1

Left Ventricle

Explanation:

Left atrium receives blood from the lungs through 4 pulmonary veins. This blood is oxygenated. This oxygenated blood then from the left atrium enters the left ventricle through a valve (mitral valve or bicuspid valve).

When the left ventricle contracts, blood is pushed into the aorta.
