How do the circulatory, respiratory or digestive system, and how they work together. Please answer in two paragraphs.

The respiratory and circulatory systems bring oxygen and nutrients to the cells. The respiratory and circulatory systems work together to maintain homeostasis. The respiratory system moves gases into and out of the blood. The lungs contain the bronchi, bronchioles, and alveoli. Digestive System gets nutrient from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go. It isn’t 2 paragraphs but I hope it works for u!
