How does circulatory system provide nutrients?

The circulatory system provides nutrients by transporting blood, which carries essential substances like glucose, amino acids, and vitamins from the digestive tract and liver to cells throughout the body. Nutrient-rich blood is pumped from the heart through arteries, reaching capillaries where the exchange of nutrients occurs. In the capillaries, nutrients diffuse into tissues, while waste products are collected for removal. This efficient system ensures that every cell receives the necessary components for energy production and overall function.
