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.

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
