The ____ system transports water soluble nutrients after they are absorbed while the ____ system transports fat soluble nutrients.
A
circulatory; lymphatic
B
lymphatic; circulatory
C
endocrine; circulatory
D
both circulatory
Explanation: 

Detailed explanation-1: -Fat-soluble vitamins are transported through the body by being absorbed and stored in fat. Water-soluble vitamins are dissolved in water and transported through the body.

Detailed explanation-2: -Blood is the conduit and blood vessels are the highway that support nutrient and molecule transport to all cells. Water-soluble molecules, such as some vitamins, minerals, sugars, and many proteins, move independently in blood.

Detailed explanation-3: -If the absorbed nutrient is water soluble it will be absorbed into the blood and if the nutrient is fat soluble it will be packaged into a special transport package, called a chylomicron, and absorbed into the lymph. For water soluble nutrients, the first stop is the liver.

Detailed explanation-4: -The second function of the lymphatic system is the absorption of fats and fat-soluble vitamins from the digestive system and the subsequent transport of these substances to the venous circulation. The mucosa that lines the small intestine is covered with fingerlike projections called villi.
