First of all, humans have their two lungs to breathe, which are covered in over 150 million alveoli, meaning a very, very large surface area, which means more oxygen is taken in.

Second of all, the alveoli are covered in capillaries, meaning that gas exchanges happen extraordinarily fast - with each breath.
