why does the left atrium and the left ventricle on the right side
The heart is made up of four chambers. The chambers on the right side of the heart are the right atrium and right ventricle. The right atrium receives deoxygenated blood from the body via the superior and inferior vena cava (major veins). The blood then flows to the right ventricle where it is then pumped, via the pulmonary circuit, through the pulmonary artery to the lungs for gaseous exchange (CO 2 out, O 2 in). The chambers on the left side of the heart are the left atrium and left ventricle.
