Which part of an individual villus forms part of the lymphatic system and absorbs fats from the lumen of the small intestine?

I believe the answer is the lacteals. 
Lacteals are structures that are in the middle of each villi; they are lymphatic capillaries that absorbs dietary fats in the villi of the small intestines. Triglycerides are emulsified by bile and hydrolyzed by the enzyme lipase, resulting in a mixture of fatty acids and monoglycerides. The lacteals merge to form larger lymphatic vessels that transport chyle to the thoracic duct where it is emptied into the blood stream at the subclavian vein. 

1.54 L

Explanation:

Camels use water obtained from the process of cellular respiration when they use fats as a substrate.

Suppose the fat used during respiration is Tripalmitoylglycerol which contains 3 palmitic acid or Palmitoyl-CoA attached to the esters.

The molecular weight of Tripalmitate is 807 g/mol  therefore 1000 g of fat will have 1000/807 = 1.24 moles of Tripalmitate x 3 = 3.72 moles of Palmitoyl CoA.

Now according to the Beta oxidation reaction,

Palmitoyl CoA + 23 O₂+ 108 ADP + 108 Pi > 16 CO₂ + 108 ATP + 23 H₂O + 8 Acetyl CoA

1.23 moles of  Palmitoyl CoA produce 23 H₂O therefore  

3.72 will produce Palmitoyl CoA will produce= 3.72 x 23 H₂O

= 85.56 H₂O molecules.

Now, 85.56 H₂O molecules will yield

= 85.56 x 18                       ( MW of water=18)

= 1541.8 g

= 1.54 L

Thus, 1.54 L is correct.
