What key function is blood associated with in relation to nutrient transport?

Blood plays a crucial role in transporting essential nutrients to cells throughout the body, including glucose and vitamins. The circulatory system, through blood, delivers these nutrients from the digestive system and other areas where they are absorbed into the bloodstream. Once in the bloodstream, glucose is used as a primary source of energy, while vitamins support various bodily functions such as immune response, energy production, and tissue repair. This process is vital for maintaining the health and functionality of cells, enabling them to perform their necessary physiological roles efficiently. Therefore, the delivery of glucose and vitamins via the blood is fundamental to overall metabolic processes and cellular health.
