Which of the following nutrients does the circulatory system transport?

The circulatory system plays a crucial role in transporting nutrients throughout the body, including amino acids. Amino acids are the building blocks of proteins and are vital for various physiological functions, such as muscle repair, immune response, and synthesis of hormones and enzymes. When proteins are consumed, they are broken down into amino acids during digestion. These amino acids are then absorbed into the bloodstream through the intestinal walls and transported by the circulatory system to cells and tissues where they are needed for various biological processes.

While vitamins, fats, and minerals are also transported in the body, the question specifically addresses the primary role of the circulatory system in nutrient transport. In this context, amino acids represent a direct and essential nutrient type that relies on the circulatory system for distribution following protein digestion. The transport of nutrients via the circulatory system highlights its importance in sustaining bodily functions and maintaining overall health.
