Final answer:
b.Blood flows directly from the digestive system to the liver through the portal vein, where the liver processes and regulates nutrients. The liver also produces bile, which is essential for fat digestion in the small intestine.
Step-by-step explanation:
The relationship between the digestive system and the liver is that blood flows directly from the digestive system to the liver through the portal vein. The liver serves as a vital organ in the processing and regulation of nutrients. It produces bile, which is necessary for the emulsification of fats in the small intestine.
Bile is secreted by the liver and delivered to the duodenum of the small intestine primarily through the common bile duct. When digestion is not occurring, bile is stored in the gallbladder. Additionally, the liver filters blood coming from the digestive tract, detoxifies chemicals, metabolizes drugs, and secretes substances vital to digestion.
The correct statement that describes the relationship between the digestive system and the liver is option b. Blood flows directly from the digestive system to the liver through the portal vein. The liver is an important organ in the digestive system as it receives blood from the digestive organs through the hepatic portal vein. This allows the liver to process nutrients and toxins before they enter the systemic circulation.
