Where does the absorption of protein and carbs take place?
Formerly a CMU Chippewa!
small intestine I believe.
"It is often said, mainly by the "no-contests", that although there is no positive evidence for the existence of God, nor is there evidence against his existence. So it is best to keep an open mind and be agnostic. At first sight that seems an unassailable position, at least in the weak sense of Pascal's wager. But on second thought it seems a cop-out, because the same could be said of Father Christmas and tooth fairies. There may be fairies at the bottom of the garden. There is no evidence for it, but you can't prove that there aren't any, so shouldn't we be agnostic with respect to fairies?"
"Out of all of the sects in the world, we notice an uncanny coincidence: the overwhelming majority just happen to choose the one that their parents belong to. Not the sect that has the best evidence in its favour, the best miracles, the best moral code, the best cathedral, the best stained glass, the best music: when it comes to choosing from the smorgasbord of available religions, their potential virtues seem to count for nothing, compared to the matter of heredity. This is an unmistakable fact; nobody could seriously deny it. Yet people with full knowledge of the arbitrary nature of this heredity, somehow manage to go on believing in their religion, often with such fanaticism that they are prepared to murder people who follow a different one."
"Bah. You know I hate poor people."

the breakdown of carbs begins in mouth, the breakdown of proteins in stomach, absorption = smallintestine

The stomach produces gastric juice and mixes it with the food. This gastric juice contains enzymes that begin the digestion of proteins. Proteins are the only substances digested in the stomach. Proteins are only partially digested in the stomach. The food is churned and mixed with stomach fluids until a thick paste called chyme is produced. The chyme passes through the stomach into the small intestine.
The small intestine is a long, coiled organ about one inch in diameter. The small intestine may be 7.5 to 9 meters in length. Digestion is completed in the small intestine. The liver releases bile into the small intestine. Bile prepares the fats for digestion. Pancreatic juice contains enzymes that digest carbohydrates and fats. It also contains enzymes that continue the digestion of proteins. The walls of the small intestine release enzymes that complete the digestion of all three basic nutrients. In the walls of the small intestine are millions of small projections called villi. These villi contain many small blood vessels. Digested food is absorbed into these blood vessels and carried to all body cells.
The material that has not been absorbed moves into the large intestine, or colon. Here water and salts are absorbed, and the remaining solid waste goes out of the body
