What role does the circulatory system play in removing waste products from the body?

Question

BlackTom AI · Accepted Answer

Consider the overall role of the circulatory system in waste removal by examining what each option implies.
Option a: 'It eliminates waste through the respiratory system.' While the respiratory system expels certain wastes (like carbon dioxide) from the blood, the circulatory system itself does not primarily eliminate waste; it simply transports wastes to organs that perform detoxification or excretion.
Option b: 'It transports waste products to the liver for detoxification.' This is accurate because the circulatory system carries waste-containing blood to the liver, where detoxification processes occur via hepatic metabolism and processing of toxins before they are excreted or further processed.
Option c: 'It carries food to the digestive system.' The circulatory system does deliver nutrients absorbed from the digestive tract to body tissues, not transport food itself to the digestive system; digestion occurs mainly within the digestive tract.
Option d: 'It filters waste products through the gall bladder.' The gallbladder stores bile produced by the liver; it does not filter waste. Filtering of wastes is not a function of the gallbladder, which is more about fat digestion via bile.
Overall, option b correctly identifies the circulatory system’s role in moving waste to the liver for detoxification, while the other options misstate where waste is eliminated, how nutrients are moved, or which organs perform filtration.
