I am not quite sure of the main reason but here are some:
1. so that the fat absorbed in the small intestine (particularly in the ileum) passes through adipose (fat) tissue first.
2. So that fat by-passes the liver
3.transport of fat in lymph may reduce risk of plaque in
arteries

What happens to fat in the small instetine?
It undergoes a process known as emulsification. Bile, which is produced in the liver and stored in the gallbladder, is added to the chyme (food + digestive enzymes) in the small intestine portion called the duodenum. Here the bile breaks it down into tiny particles where it can be diffused into the lacteals. The lacteals are the part of the lymphatic system that transports the fat to different parts of your body. Every cell in your body needs fat to be healthy. It is part of the cell membrane, sometimes referred to as the phospholipid-bilayer. The lipid part of the name stands for fat.
What helps fat move through the intestinal wall?
A process of emulsification which occurs occurs in the presence of bile. this allows the specialized lymphatic vessels called lacteals to draw the fat into the lymphatic system to be distributed throughout the body and to areas where it is needed.
What is tendons blood and fat are examples of?
what are tendons, blood, and fat are examples of
What happens to materials not absorbed into your blood?
They are eliminated from the body as wastes
What are Lacteal?
A lacteal is a specialized lymph vessel that absorbs fats in the small intestine.
Fats and fat-soluble vitamins are absorbed by?
lacteals
What is collected by the lacteals?
Lacteals collect absorbed fat, fat-soluble vitamins, and other nutrients from the small intestine. These nutrients are then transported through the lymphatic system back into the bloodstream.
Digested fats are absorbed from the intestine by the lymph capillaries?
Lacteals are the specialized lymphatic capillaries of the small intestine which transfer fats from the digetive system into the blood. Chyle (pronounced Kyle) is milky fluid found in the lacteals formed by fat globules and lymph.
Why there are fat droplets in the lymph leaving the ileum?
Fatty acids and glycerol are absorbed in the ileum. Fat enters the lacteals of villi, which empty the lacteals into the lymph vessels. Transport of fat in lymph may reduce risk of plaque arteries.
How does absorption of fat differ from glucose?
Fat is absorbed by lacteals in the small intestine these have large surface areas to help with absorption and capillaries to absorb the fatty acids. Glucose and Amino acids is absorbed in the glomerulus in the kidney transported by the blood to the heart etc then it is reabsorbed in the bowman's capsule in the kidney.
What take in nutrients through the small intestine?
If you refer to the physical "thing", nutrients is absorbed into the blood capillaries (other than fat molecules) and lacteals (fat molecules only) in the villi, which are lining the small intestine. The nutrients absorbed into the blood is then transported via the hepatic portal vein to the liver where the liver further distribute the blood to our body. The fat absorbed into the lacteals evntually join with the lymphatic system and finally empties into a vein near the neck. If you refer to the mechanism, the "force" that helps the absorption of nutrients would be the concentration gradient between the blood in the blood capillaries and the chyle in the intestines. Also, cells in the small intestines actively transports nutrients (e.g. amino acids, glucose) using ATP.
Can molecules of undigested fat and some fatty acids be absorbed by lymph vessels called lacteals?
Yes, lacteals are small lymphatic vessels that absorb fats and fatty acids from the small intestine.
What does lacteals do?
Lacteals are lymphatic vessels found in small intestinal villi. While other nutrients such as amino acids and saccharides are absorbed into the blood stream, lacteals and the lymphatic system are used to absorb fats.
Which digested foods are absorbed by lacteals?
Triglycerides are absorbed by the lacteals of the small intestine. Triglycerides go into the lymphatic system and are converted into chyle.
What is a special lymphatic capillary in the small intestines?
The specialized lymph capillaries located in the small intestine are called lacteals. These lacteals are important in that they absorb fat.
In the small intestine where are lipids absorbed?
In the absorptive enterocyte of the small intestine.
What else other than the blood carries nutrients throughout the body?
The lacteals, or lymph vessels do. The blood absorbs amino acids and sugars from the small intestine, while lacteals absorb triglycerides (fat), cholesterol, and the fat-soluble vitamins. These three nutrients are built up into chylomicrons in the epithelium of the small intestine, and it is these chylomicrons that are taken up by the lacteal.
