The Respiratory System

• it is inhaling Oxygen and exhaling Carbon Dioxide. It is the process that is fueled by oxygen

• it is like a hole that collects

• you breathe through it

• it is lined with tiny hairs that helps filter out waste

• it is a flap of tissue that covers the wind pipe when you eat

• it is your vocal cords

• it is your windpipe that pushes air down into the lungs

• it has bronchus passages into which air is drawn, so that oxygen can pass into the blood and carbon dioxide be removed

• it looks like an upside down tree, it allows for different airways and movement

• it is a dome shaped muscle under the lung that helps you breath

• muscles attached to your ribs contract and pull upward - the diaphragm contracts and pulls down the bottom of your chest

• muscles attached to your ribs relax and pull downward - diaphragm relaxes and pulls up the chest

• it exchanges gasses in the lungs
