We use various muscles to increase chest volume more dramatically. in the same way as in relaxed breathing the expansion of the chest cavity draws air in so the lungs fill up. the relaxation of the chest cavity pushes air out. muscles can also force the chest cavity to contract even further, pushing even more air out. Humans get oxygen by filling their lungs with fresh air. the air we breathe in typically consists of about 78% nitrogen gas, about 21% oxygen gas, and less than 1% argon gas and traces of several other gasses. we remove carbon dioxide from the body by breathing out stale air. The human body is complex! in this lesson, it is broken down into smaller, manageable parts. students will build a lung model and discover how different parts of the respiratory system work together to make breathing possible. next, they will discuss how this system works together with other systems in the body so oxygen can reach every cell of.
