Expert Answer:

Human heart shows 4 chambers, 2 atria and 2 ventricles. Atria are the receiving chambers whereas ventricles are the conducting chambers. The right side of the heart has deoxygenated blood whereas the left side contains oxygenated blood. The left and right side are sparated by septum. Various blood vessels are associated with the heart which help to carry blood away and bring blood towards the heart. Lungs oxygenate the deoxygenated blood and return it to the left atrium. The left ventricle pumps this oxygenated blood to the rest of the body.
