Solution

In the Systemic circulation the left ventricle sends the oxygenated blood into the aorta. Aorta then supplies this oxygenated blood to various parts of the body. The deoxygenated blood then comes from various parts of the body into the right auricle. Thus, systemic circulation starts from left ventricle and end at right auricle of the heart.

So the option is Right atrium
