Verified step by step guidance1
Understand the role of lacteals: Lacteals are specialized lymphatic vessels that absorb dietary fats in the form of chylomicrons during digestion.
Identify the location where fat absorption primarily occurs: Fat digestion and absorption take place in the small intestine, specifically in the villi of the intestinal lining.
Recall the anatomy of the small intestine: The small intestine is divided into three sections—duodenum, jejunum, and ileum. Lacteals are found within the villi of these sections.
Eliminate incorrect options: The esophagus, large intestine, and stomach do not have structures specialized for fat absorption like lacteals.
Conclude that lacteals are located in the small intestine, as this is the site of fat absorption and the presence of villi containing lacteals.
