Which vessel delivers nutrient-rich blood to the liver from the digestive tract?

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.

not the best question format lol but what i think might as scale color is controlled by a single gene with two alleles, the green allele and the yellow allele. when moths that are homozygous for green scales are mated with moths that are homozygous for yellow scales, 100% of the offspring have green scales.
