Question 1 Report

The mammalian vein which starts with and ends in a capillary network is the

pulmonary vein

mesenteric vein

renal vein

hepatic potal vein

Answer Details

The mammalian vein that starts with and ends in a capillary network is the hepatic portal vein. The hepatic portal vein is responsible for carrying blood from the gastrointestinal tract, pancreas, and spleen to the liver. It starts in capillaries that are present in the walls of the digestive tract and ends in the capillary network of the liver. The blood that flows through this vein is rich in nutrients and other substances that have been absorbed from the intestines and processed by the pancreas. The other options are not correct because they do not start and end in capillary networks. The pulmonary vein carries oxygenated blood from the lungs to the heart and does not start in a capillary network. The mesenteric vein drains blood from the intestines but does not end in a capillary network. The renal vein carries blood from the kidneys to the heart and does not start in a capillary network.
