Nutrients primarily enter the veins rather than arteries because they are absorbed into the bloodstream from the digestive system through the capillaries in the intestinal walls. These capillaries merge into veins, specifically the hepatic portal vein, which transports nutrient-rich blood to the liver for processing. In contrast, arteries carry oxygen-rich blood away from the heart to various tissues, which do not directly absorb nutrients in the same way. Thus, the nutrient absorption process is geared towards the venous system.
artery
The function of the coronary artery is to carry oxygen and nutrients to the myocardium (heart muscle), it does not actually take the carbon dioxide away, (that is the job of the great and small cardiac veins).
