Answer 1

The circulatory system, also known as the cardiovascular system, is crucial for transporting blood throughout the body. It carries oxygen and nutrients to cells and takes away waste products like carbon dioxide. This system works closely with the respiratory system, which is responsible for bringing oxygen into the body and releasing carbon dioxide when we breathe out. Together, these systems help maintain homeostasis by ensuring that our cells have the necessary resources to function properly and that waste is efficiently removed. By working in harmony, they keep our internal environment stable, which is vital for overall health.
