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.
Elatic recoil.
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.
tricuspid valve
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.
ductus arteriosus
They are essentially the same.
nothing
I answered this question last week... but anyway... the aorta has to accommodate much higher pressures from the left ventricle, ergo it is thicker.
please tell me the difference between thickness
Coronary or cardio is blood flow. Pulmonary or respiratory is breathing.
The difference in thickness between 3/32 and 1/8 inch is 1/32 inch.
Heart
they carry deoxygenated blood
Elatic recoil.
The main difference is the thickness of the pipe Compare to A Class pipe B Class pipe thickness is more.Like that Compare to B class pipe C Class pipe thickness is more.
There is no difference, its just a different way of saying the same thing
Wall thickness
