No matter what we eat or drink, the body just seems to know exactly how to make use of it. How does the body recognize that protein and its corresponding amino acids from ground beef works all the same as protein from chicken, fish, or whatnot?
Do the nutrients just flow idly through the bloodstream and get pulled into where it needs to like a radio wave frequency?

Okay so it doesn’t. The acids and other digestive and non digestive organs simply react differently to different bonds and chemicals. So the amino acids are processed in a different way simply because they are a different structure! It’s not so much our body going this is chicken i need to do this and more our body being evolved and changed over time to follow a very specific pattern and use very specific acids and other things to automatically sort everything.
For example your spit is really good at taking appart starches and the like. But less good at anything else.
As per uptake the walls of your digestive trackt arent fully closed they are closed enough to not allow most things through but specific substances that we need to enter our blood for example sugars and proteins are capable of passing through this wall to do so.
