Why Studying Medicine is More Difficult than Learning Language (in My Opinion)

I still figure out the best way to study in medical school and I compare it to my language learning.
I learn language by listening to audio file while reading the text, or simply by watching video. Doing so, I learn almost all things needed while learning language: listening, speaking, reading, and writing. After listening, I try to speak the words thus I learn to speak. While reading a text, I see the letters thus I also learn to write.
I guess later I have to study medicine as a whole thing. Should I? I mean, I should understand some histology and physiology while studying anatomy then I will learn patophysiology while studying physiology and histopathology while studying histology, etc. Well, it won't be so simple as language learning process but I will try.
