Why pressure in aorta is bigger than pressure in pulmonary trunk?

Hello. I think it's not about oxygenation. It's all about the Left ventriculus of the heart. And left ventriculus does a systolic function that creates pressure. Also, the veins walls are a little bit different; its thinner and have valves, all because of its pumping blood from the bottom to up

The pressure of the pulmonary trunk is less than the aorta because it’s role is to supply deoxygenated blood to the lungs which is a rather short distance. In contrast, the aorta supplies and pumps oxygenated blood to the rest of the body.

You're right although I think it has something to do with the distance (yes, you're right about it being short) and how the blood comes from the right ventricle of the heart whose pressure isn't that high compared to the pressure from the left ventricle

Aorta - Systemic circulation req more pressure to pump from big left ventricle

Simply because the lft ventricle has a larger muscle suitable for its function yo send blood all over body, not like pulmonary that sends blood to only lung... Every pressure is suitable for its function dude

1. Wall of arteries and veins have different histological characteristics thus the arterial wall contains much more smooth muscle tissue. 2. Left ventricle musculature is better developed
