Answer:
The correct answer is option C. hepatic portal system.
Explanation:
The hepatic portal system involves hepatic portal veins and its accessory tributaries. The hepatic portal system collects blood from digestive organs and spleens that consist of nutrients absorbed from these organs and circulate to the liver.
This system is unique to circulate both oxygenated and deoxygenated blood. This system involves most of the digestive organs from the esophagus to the end of the canal.
Thus, the correct answer is option c. the hepatic portal circulation.

Answer: D) precapillary sphincters relax.
Explanation:
Blood flow to a tissue will decrease if precapillary sphincters relax as, capillaries provides glucose and oxygen to the cells and allows blood to flow through it when the muscle ring known as the precapillary Sphincters get relaxed. The blood flow is stopped when the precapillary sphincters constrict flow of blood. As, certain chemical signals causes feeder arterioles to dilate and bring more blood into local areas then, it causes precapillary sphincters to relax.
