In what way does the circulatory system support the digestive system?

• A. It transports oxygen to the digestive organs.
• B. It removes waste products from the digestive system.
• C. It transports absorbed nutrients from the digestive system to cells.
• D. It regulates blood pressure in the digestive tract.

Answer: (C)

The circulatory system plays a crucial role in supporting the digestive system primarily by transporting absorbed nutrients from the digestive system to cells throughout the body. When food is digested, nutrients such as sugars, amino acids, and fatty acids are absorbed into the bloodstream from the intestines. The circulatory system then distributes these nutrients to various tissues and organs, where they are utilized for energy, growth, and repair. This direct connection between the digestive and circulatory systems ensures that the body receives essential nutrients needed for maintaining overall health and function.

While transporting oxygen to digestive organs, removing waste products, and regulating blood pressure within the digestive tract are important functions, they do not directly address the primary pathway through which nutrients from food are delivered to the body's cells. The transportation of nutrients is a critical aspect of the interaction between the circulatory and digestive systems, making it the focus of this question.
