this is a powerpoint on the repiritory system.

1. The Respiratory System By Summer Temple Room 8-73

2. The respiratory system Respiratory system is very important Used for breathing Inhale threw nose Breathe goes threw pharynx Carries air down windpipe The epiglottis covers top of larynx ( keeps food out of lungs)

3. The respiratory system continued voice box sits on top of the windpipe vocal cords that help you talk, sing, hum, or cough vocal cords take air to the lungs bronchial tree takes air to the bottom of the lungs In the lungs thousands of tiny air sacs called Alveoli extend off the end of the smallest bronchioles Finally oxygen enters your bloodstream

4. Nose You breathe through your nose You smell through your nose Your nose starts the respiratory cycle Your nose cleanses the air as it passes threw

5. Pharynx It is located in your throat Food goes threw it Carries Air threw it down to the windpipe

6. Epiglottis A piece of cartilage Blocks food from going to lungs Leaf shaped Covers the top of larynx

7. Larynx Also known as the voice box Funnel shaped organ Located in the throat Passes through hear from epiglottis down to the vocal cords

8. Vocal cords Vocal cords are also known as vocal folds Structures in the larynx Designed to vibrate when air is passing by Helps you talk, sing, hum, or cough

9. Trachea Also known as the wind pipe Bony tube Connects nose to the mouth to lungs

10. Bronchial tree Part of the internal structure Known as the lung tree Allows humans to exchange air Have little air sacs called Alveoli extend off the end of the smallest bronchioles

11. Lungs A vital organ Lungs have lobs left lung 2, right lung 3 Pink and spongy Part of the respiratory system

12. Alveoli They are Tiny air sacs Located In the lungs Come the end of the bronchial trees There are thousands of them
