carries blood from the torso and lower body to the right side of the heart

Right/left ventricle

receive blood from the heart's upper chambers (atria) and pump it to the rest of the body

Pulmonary trunk

carry blood from your heart to your lungs

Pulmonary artery/vein

carry oxygen-poor blood from your heart to your lungs & carry oxygenated blood back to the heart

Foramen ovale

connects the atriums to allow blood to circulate through the fetus w/o going to the lungs first

Ductus arteriosus

connects the aorta to the pulmonary artery in a fetus to prevent blood from going to the lungs

Aorta

transporting oxygen rich blood from your heart to the rest of your body

Coronary artery/vein

provide the main blood supply to the heart
