Final answer:
The correct answer to the student's question is A) Liver, Bloodstream. The lymphatic system is responsible for transporting nutrients that leave the digestive system, bypassing the liver initially and later entering the bloodstream via the thoracic duct connected to the subclavian vein.
Step-by-step explanation:
Nutrients leaving the digestive system via the LYMPHATIC system bypass the liver at first but eventually enter the bloodstream via the thoracic duct, which opens into the subclavian vein. The correct answer to this question is A) Liver, Bloodstream. The lymphatic system plays a key role in transporting nutrients, particularly fats and fat-soluble vitamins absorbed from the intestine. These nutrients enter the lymphatic vessels before passing into the larger lymphatic ducts, ultimately reaching the thoracic duct, and then entering the bloodstream through the subclavian vein. Once in the bloodstream, these nutrients are transported to the liver for processing. The lymphatic system's structure includes capillaries and larger lymphatic vessels that contain numerous valves to prevent backflow, ensuring lymph flows in one direction. Lymph nodes positioned strategically throughout the body serve as filtration and immune response centers. The extensive network of the lymphatic system works in tandem with the cardiovascular system to maintain fluid balance and protect against pathogens.
