How does the small bowel work? Why is it important?

Do you have a solid understanding of small intestinal physiology?

How do we digest and absorb carbohydrates, proteins and fats? How about water, electrolytes and vitamins? What are brush border enzymes and how about enterohepatic circulation?

Digestion and absorption gets complicated. Let's make it easy!

MUST HAVE SURGERY BOOKS

In today's talk we're going to build on the foundation from last week's anatomy lesson and learn everything about small bowel physiology, the really important bits. As a surgeon it's important to understand physiology so you can know the consequences of particular operations!

What happens when you resect the terminal ileum? Does this impact the absorptions of any particular vitamins?

What happens if you bypass part of the small bowel, like the duodenum?
