Question

Quizplus · Accepted Answer

After absorption, larger fats and fat-soluble vitamins are first released into the lymphatic transport system, which eventually empties into the vascular system. This is because these molecules are too large to enter directly into the capillaries of the vascular system and need to be transported via the lymphatic vessels. The other choices (excretory, mesentery, and vascular) do not play a role in the absorption and transport of fats and fat-soluble vitamins. The larger fats and fat-soluble vitamins are first released into the lymphatic transport system, not the vascular system, which is responsible for transporting water-soluble nutrients. The mesentery is a tissue that provides support to the intestine, while the excretory system is responsible for eliminating waste products from the body.
