Nutrient delivery refers to the process by which essential substances, such as vitamins, minerals, and macronutrients, are transported to cells and tissues in the body. This process is crucial for maintaining health, supporting growth, and enabling various bodily functions. Nutrients can be delivered through food, supplements, or intravenous methods, depending on individual needs. The body utilizes the digestive system to break down food into smaller components, which are then absorbed into the bloodstream. From there, nutrients are distributed to different organs and cells, ensuring that they receive the necessary elements for energy production, repair, and overall functioning.
