Answer:
A. Obtaining nutrients and getting rid of waste
Answer:
Hepatic portal vein
Explanation:
Hepatic portal vein is a blood vessel that transports blood from the gastrointestinal tract (digestive tract) and spleen to the liver. This blood vessel delivers deoxygenated blood to the liver from the small intestine. This blood transported from the digestive tract to the livers contains toxins and nutrients which have been extracted from food that have been digested.
The hepatic portal vein is about 8 cm in length in average adult and located close to the abdomen at the right upper quadrant.
