In this lab we made a to scale model of the length of our digestive system. The point of the lab was to show how truly massive your internal organs are.
I am 1.7018 meters tall and my digestive tract is about 9.23 meters long. It baffling how this system is more than 8 times the size of me. But theses lengthy organs fit inside of me due to their ability to fold and scrunch together like a spring, more specifically the large and small intestines.
My guess is that it takes around 15 hours for food to go through the entire digestive system. But according to Health and Support, it can take anywhere between 12-72 hours depending on what kind of food is ingested. Fruits and vegetables take around 12-24 hours to pass through while red meat takes 72 hours.
Digestion is the break down of food into smaller pieces and absorption is intake of nutrients from that food. The mouth, esophagus, and stomach are involved in digestion and the small intestine and large intestine are involved in absorption.
I want to learn more about metabolism and how digestion, absorption, etc have to do with it. I also want to understand what makes a "fast" or "high" metabolism. What (scientifically speaking) is going on?
