What vein are connected directly to the right ventricles?

The valve located between the right ventricle and the pulmonary trunk is?
pulmonary semilunar valve
What is the signifiance of the difference in thickness between the wall of the aorta and the wall of the pulmonary trunk?
Aorta is thicker because it has greater pressure of outflow to deal with from the left ventricle. Blood leaving the heart into the aorta has great pressure because the blood has to be carried all over the body, whereas the pulmonary trunk only pumps blood to the lungs which is an area of lower pressure.
Oxygenated blood leaves the lungs via the?
The pulmonary artery
