left vs right side of the heart

Left ventricle and left atrium are oxygen rich blood and right ventricle and right atrium and ventricle have oxygen poor blood

Single circulatory system

Blood passes through the heart once only in a complete circuit of the body e.g. in a fish

Capillaries

atria function

ventricles function

function of pulmonary veins
