Which process involves the movement of nutrients throughout the body?

The movement of nutrients throughout the body is accurately described by the concept of transport. This process involves the distribution of essential substances, such as vitamins, minerals, carbohydrates, proteins, and fats, from the digestive system to various cells and tissues throughout the organism. The circulatory system plays a crucial role in facilitating this transport, where nutrients are carried by the bloodstream to where they are needed for energy, growth, and repair.

While digestion, absorption, and metabolism are all critical components of nutrient management, they serve distinct roles. Digestion focuses on breaking down food into smaller, usable components. Absorption refers to the process of taking these nutrients into the bloodstream from the digestive tract. Metabolism, on the other hand, involves chemical reactions that convert nutrients into energy and other necessary substances for the body. Thus, the comprehensive process of moving these nutrients after they have been absorbed is effectively encapsulated by the term transport.
