Which is more difficult, breathing in or breathing out?

是吸气困难还是呼气困难？

That's because the diaphragm muscle lowers during inspiration, and that creates negative pressure in the chest to bring in air, and that negative pressure also brings a bit more venous blood back to the right atrium and right ventricle.
