Which part of an individual villus forms part of the lymphatic system and absorbs fats from the lumen of the small intestine?
Lostsunrise [7]
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.

Water present in soil is drawn by the roots of a plant through the xylem to the leaves of the plant. Plants like the large sequo
Solnce55 [7]
<span>Transport of the water from the roots to the leaves is driven through the vascular tissue called xylem. Water gets absorbed from the soil by osmosis and it must cross several cell layers (filtration system) before entering the xylem. The method used in the upward movement of water through the xylem is determined by the cohesion-tension theory (capilarity+transpiration). The transport is passive and it occures thanks to the primary force that creates the capillary action (adhesion between the water and the surface of the xylem and cohesion between individual water molecules) movement of water. Transpiration is also an important factor in the upward water movement. Transpiration in leaves creates tension (differential pressure) and because of this tension, water is being pulled up from the roots into the leaves.</span>
