Just Breathe
This type of pressure in the thoracic cavity allows air to fill the lungs.
What is negative pressure?
The structure that is made of a single layer of cells.
What is the alveolus?
This reaction in the tissues causes the pH of blood to decrease during internal respiration.
CO2 + H2O --> H2CO3 --> HCO3- + H+
The primary organ where gas exchange occurs.
What is the lung?
These tiny hairs in the nasal passage trap dust and germs.
What are cilia?
The main driving force for breathing when at rest.
What is the body's need for oxygen?
The structure that houses the vocal cords.
What is the larynx?
This temperature and pH makes hemoglobin's affinity to CO2 predominant.
What is 38 degrees Celsius and 7.35?
Dirt and other tiny particles trapped mucous found here will eventually make its way to the stomach.
What is the trachea?
This unusual activity helps clear out irritants by forcing air quickly out of the lungs.
What is a sneeze?
Names of structures which make up the thoracic cavity's closed system.
What are pleural membrane, ribs, intercostal muscles, and diaphragm?

Where air is filtered, warmed, and moistened?
What is the nasal cavity?
The flap of tissue that closes over the trachea when swallowing.
What is the epiglottis?
Transportation of oxygen to your cells is necessary for this important process.
What is aerobic cellular respiration?
The name of the structure that carries air from the trachea to the lungs.
What are the bronchi?
The transfer of oxygen from alveoli to the blood and transfer of waste and carbon dioxide from the blood to the alveoli is known as this.
What is external respiration?
Your ability to sing, shout, and speak come from vocal cords located within the...?
What is larynx?
It's possible that food can come out of your nose because of this structure.
What is the pharynx?
List in order the structures of the respiratory system through which air passes from the outside environment to the alveoli.
What is nose/mouth, pharynx, larynx, trachea, bronchi, bronchioles, and alveoli?
These structures monitor oxygen and carbon dioxide levels to regulate respiration rate.
What are chemoreceptors and the medulla oblongata?
CO2 is primarily transported back to the lungs by this molecule.
What is bicarbonate?
Non-respiratory system structures connected to the nasal cavity.
What are tear ducts and Eustachian tubes?
These organs make up the lower respiratory tract.
What are larynx, trachea, bronchi, bronchioles, and alveoli?
