What is the hard and soft palate?
The apex of the lung is the superior or inferior portion of the lung?
What is superior?
The major function of the respiratory system is the exchanging (supplying and disposing) of what two gases?
What are oxygen and carbon dioxide?
What is the amount of air exchanged during normal quiet breathing (tidal volume)?
What is 500ml
If you are to hold your breath, the body will eventually force you to breathe because of it's need to rid itself of what blood gas?
What is carbon dioxide?
What routes air and food into their proper channels and plays an important role in speech production?
What is the larynx?
What is the opening between the vocal cords called?
What is the glottis?
What are the four main events of respiration?
What are pulmonary ventilation, respiratory gas transport, external respiration, and internal respiration?
Which respiratory volume is the largest?
What is vital capacity?
What is the most common transport method for oxygen in the blood?
Oxyhemoglobin
When we swallow food or drink, what prevents the passage of these items into our larynx and lower respiratory passageways?
What is the epiglottis?
Which passageways enters the lung at the hilum?
What are the bronchi?
Inspiration and expiration (breathing) is what process?
What is the amount of air that can be forcibly exhaled beyond tidal expiration?
What is 1,200ml?
What two brain areas are involved in the rate and depth of breathing?
What are the medulla oblongata and the pons?
What are the smallest conducting passageways of the lungs?
What are the bronchioles?
What structure lines the trachea in order to propel mucus out of the lungs towards the throat?
What are cilia?
What zone is the only site of gas exchange?
What is the respiratory zone?
What is the amount of air that can be taken in forcibly above tidal volume?
What is inspiratory reserve volume?
What is it called when your respiratory rate increases due to increased oxygen demand?
What is hyperpnea?
What tissue forms the C-shaped rings that reinforce the trachea?
What is hyaline cartilage?
What is made by the goblet cells in the lining of the nasal cavity and trachea for the purpose of trapping incoming bacteria and foreign debris?
What is mucus?
What two muscles contract so we can inspire air?
What are the diaphragm and external intercostals?
What is the volume of air remaining in lung after expiration that cannot be voluntarily exhaled called?
What is residual volume?
Carbon dioxide is loaded into the blood from the surrounding cells and tissues in what phase of respiration?
What is internal respiration (gas exchange)?
