Question
Fats are absorbed by _________________________ part of villi.
Solution
Fats are absorbed by the lacteals part of villi.
Here are the steps of how fats are absorbed:
-
Digestion of fats begins in the small intestine with the help of bile salts and lipase enzymes.
-
The bile salts emulsify the dietary fats, breaking them down into smaller droplets, which increases the surface area for the lipase enzymes to work on.
-
The lipase enzymes then break down the fats into fatty acids and monoglycerides.
-
These fatty acids and monoglycerides are then absorbed by the enterocytes, the cells lining the small intestine.
-
Inside the enterocytes, the fatty acids and monoglycerides are reassembled into triglycerides.
-
These triglycerides are then packaged into lipoproteins called chylomicrons.
-
The chylomicrons are released into the lacteals, the lymphatic vessels in the villi of the small intestine, where they are transported to the bloodstream.
So, the lacteals part of the villi is responsible for the absorption of fats.
