path of tom through the right side of the heart and lungs

tom is deoxygenated and needs oxygen

first, he enters through the vena cava then goes to the right atrium.

-

the right atrium sends tom through a valve to the right ventricle,
from there the right ventricle will send him to the pulmonary artery

-

the pulmonary artery sends tom to the lungs where he will become oxygenated
