Fluids are observed everywhere in the world. In fact, some living organisms can be made of up to 90% water. Even humans consist of over 60% water on average. Therefore, it is important to learn about fluid behavior and properties. In this section, we cover the physics behind fluids, how gas interacts with fluids, and the circulatory system in the human body.
