👉 Noncirculatory refers to a body system that has no blood flow or circulation. This means that there is not enough blood flow to carry nutrients, oxygen, and other vital substances throughout the body. Noncirculatory systems are often found in organs like the heart, liver, and lungs, where blood supply is limited due to their size and function. In contrast, circulatory systems have blood flow that allows for efficient nutrient transport and oxygenation of tissues.
