The small intestine is the region of your gut where the majority of the nutrients and water from your digested food is absorbed. As a result, it’s microscopic structure is highly specialized to maximize this process. For example:

The image you see shows the lining of the small intestine.

The three tenors are folds in the wall of the small intestine called plicae circulares. If you were traveling inside your own intestine you would be able to see them as large circular folds that corkscrew along the length of the intestine. They increase the surface area of the lining (mucosa) of the small intestine but also help to slow down the passage of food. Slowing the food down means that there is more time to absorb those nutrients!

The ‘hair’ on the heads of the three singing plicae are finger like projections called villi. By folding the mucosa of the small intestine into these tiny fingers the surface area across which absorption can take place increases massively.

Each finger like hair on the head of each plica is lined by absorptive epithelial cells called enterocytes. It is difficult to see in this image but the plasma membrane on the luminal aspect (food side) of each enterocyte is also folded into tiny hairs - called microvilli. This is the surface across which the absorption takes place.

So by folding the small intestine into plicae ...then folding the mucosal surface lining the plicae into villi...then folding the membranes of the enterocytes that line the villi into microvilli...we have created a region of intestine that has an enormous surface area for absorption to occur. 

Now add this to the fact that the small intestine is also long and its clear to see why we are incredibly efficient at getting the maximum nutrients out of the foods we eat.

It also explains those bum notes after a hearty meal 💨
