RESPIRATORY SYSTEM (SCIENCE) Flashcards
A system that ensures that your body gets the oxygen it needs.
Respiratory system
Uses oxygen to make energy from food.
Body cells
What are the main parts of the respiratory system?
- Nose
- Trachea
A passageway in your throat that takes air into and out of your lungs
Trachea
What is the trachea also known as?
Windpipe
A flap of tissue in the back of your mouth that keeps food out of your trachea.
Epiglottis
Two passageways that branch from the trachea, one to each lung
Bronchi
Two large organs that exchange oxygen and carbon dioxide
Lungs
A large, dome-shaped muscle below the lungs that expands and compresses the lungs, enabling breathing
Diaphragm
Are tiny, hair-like structures in your nose that trap dirt particles from the air you breathe.
Cillia
How does air enter our body?
Through our nose and mouth
A process wherein your diaphragm moves down and your rib cage expands.
Inhalation (inspiration)
A process wherein your diaphragm moves up and your ribs move in and down.
Exhalation (expiration)
Give all the SEVEN problems of the respiratory system.
- Asthma
- Cold/Flu
- Emphysema
- Lung Cancer
- Mouth and Tongue Cancer
- Pneumonia
- Tuberculosis
Disorder in which airways narrow.
Asthma
Illnesses caused by viruses.
Cold/Flu
Disease in which alveoli lose their ability to stretch.
Emphysema
Uncontrolled growth of cells that reproduce abnormally in
the lungs.
Lung Cancer
Uncontrolled growth of cells in the mouth and tongue.
Almost always caused by tobacco use.
Mouth and Tongue Cancer
Bacterial or viral disease that affects the lungs.
Pneumonia
Bacterial disease that affects the lungs.
Tuberculosis
True of False. All tobacco products contain substances that can cause cancer.
True
Inflates during inhalation and deflates during exhalation. They are the gateways for oxygen into the body.
Alveoli
What are the parts of the respiratory system?
- Nasal Cavity (Nose)
- Pharynx
- Larynx/Voice Box
- Trachea/Windpipe
- Lungs (Right and Left)
- Bronchi (singular. Bronchus)
- Bronchioles (singular. Bronchiole)
- Alveoli
- Diaphragm
Divides into two passageways for air and food.
Pharynx
The lungs are covered by a two-layer membrane called the?
Pleura
