Answer:
The statement is true.
Explanation:
The soluble nutrients from digestion (amino acids, sugars and soluble vitamins) travel from the intestine to the liver through the portal vein. The transport of lipids, cholesterol and fat-soluble vitamins is much more complex, since they are not soluble, they cannot be sent to the portal vein because there they would quickly produce fat deposits, and must be sent through the lymphatic system. Among the functions of the lymphatic system, two should be highlighted: its central role in the immune system, and its role in the transport of lipids and cholesterol from the diet. Lymphatic ducts from the intestine converge into the thoracic duct that joins the bloodstream near the entrance to the superior vena cava, where the lymph content passes into the systemic blood circulation.
