26 Οκτ 2024 · How the Respiratory System Works. When we breathe in, or inhale, oxygen travels from our nose or mouth down the trachea and into our lungs. In the lungs, the oxygen moves into the alveoli and is absorbed into our blood. Our blood then carries the oxygen to all parts of the body. At the same time, the blood picks up carbon dioxide, a waste gas ...
Covers the following skills: Know that the human body has many parts that interact to function as systems (e.g., skeletal, muscular) and describe the parts and their specific functions in selected systems (e.g., the nose, lungs, and diaphragm in the respiratory system).
body that allow you to breathe are called your lungs. You have two of them that work together, located in your chest inside the rib cage.

The bad air is a gas called carbon dioxide, which your body cannot use.

The lungs and respiratory system allow us to breathe. They: Bring oxygen into our bodies (called inspiration, or inhalation). Send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration. How Do the Lungs and Respiratory System Work? The cells in our bodies need oxygen to stay ...
This lesson explores how air flows in and out of our lungs, compares lung breathing with other breathing mechanisms, and discusses why humans might have developed lung-breathing. Relaxed breathing is a reflex; we do not have to think to breathe.
