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.

∙ 13y agoFrom the pulmonary trunk the blood goes to the lungs to get oxygen. The aorta needs more force than the pulmonary trunk because it is sending the blood throughout the body, thus to places much farther than the distance to the lungs.

∙ 12y agoI answered this question last week... but anyway... the aorta has to accommodate much higher pressures from the left ventricle, ergo it is thicker.

What condition is indicated by the structural difference between systemic and pulmonary arteries?
Elatic recoil.
Are there valves in the pulmonary artery or the aorta.?
There are not valves in the pulmonary artery or the aorta. However there are valves between these and the heart. Between the right ventricle and the pulmonary artery there is a valve referred to as the pulmonary semilunar valve. Between the left ventricle and the aorta there is a valve called the aortic semilunar valve.
What is the name of the heart valve that lies between the right ventricle and the pulmonary arteries?
tricuspid valve
What is the valve between the right ventricle and the pulmonary artery?
The pulmonary or pulmonic valve (a semilunar valve) controls blood flow from the right ventricle to the "pulmonary trunk" that branches into the two pulmonary arteries carrying blood to the lungs.
What is a fetal shunt between the aorta and the pulmonary trunk?
ductus arteriosus
