Larger organisms need a circulatory system to transport substances around their body. Here's a step-by-step explanation:

1. Larger organisms have many cells, some of which are deep within the body, far from the external environment. These cells need a way to get nutrients and remove waste products.

2. The circulatory system, which includes the heart, blood, and blood vessels, serves this purpose. The heart pumps blood, which carries nutrients and oxygen, throughout the body via the blood vessels.

3. When the blood reaches the cells, it delivers the necessary nutrients and oxygen. At the same time, it picks up waste products and carbon dioxide, which are byproducts of cellular processes.

4. The blood then carries these waste products away from the cells and back to the heart. From there, it's pumped to the lungs (in the case of carbon dioxide) to be exhaled, or to the kidneys (for other waste products) to be filtered out and excreted in urine.

5. In this way, the circulatory system helps larger organisms transport substances around their body, ensuring that all cells receive the nutrients they need and can effectively remove waste products.
