Anatomy of Respiratory System
This is where inhaled air is first warmed and moistened.
What is the nasal mucosa?
This is the term for the movement of air in and out of the lungs.
What is ventilation?
This is the diffusion of oxygen from the alveoli to the blood.
What is external respiration?
The CNS respiratory centers are found in these places.
What are the medulla and pons?
This serous membrane lines the chest cavity.
What is the parietal pleura?
The trachea branches into these.
What are the primary bronchi?
This is what happens to the diaphragm during inhalation.
What is contracts and moves downward?
This is the exchange of gases in tissues.
What is internal respiration?
The average rate of respiration is this.
What is 12–20 breaths per minute?
This is the primary function of serous fluid.
What is prevent friction?
These bones make up the nasal cavity.
What are the vomer and ethmoid?
These pull the ribs up and out for inhalation.
What are the external intercostal muscles?
Oxygen is bonded to ______ in the ______ when transported in the blood.
What is hemoglobin and RBCs?
These are the nerves to the diaphragm.
What are the phrenic nerves?
Decreasing surface tension in the alveoli is the function of this.
What is pulmonary surfactant?
This covers the larynx when swallowing to prevent choking.
What is the epiglottis?
The name of air pressure in the alveoli.
What is intrapulmonic pressure?
Most CO₂ is transported in the blood as:
What is HCO₃ in the plasma?
This is the most important regulator of respiration because excess makes you acidic.
What is carbon dioxide?
These two are made of simple squamous epithelium which allows for diffusion.
What are alveoli and pulmonary capillaries?
The trachea is ___________ to the esophagus and _______________ to the larynx.
What is anterior and inferior?
The name of the pressure outside the body.
What is atmospheric pressure?
Oxygen is released from hemoglobin when the partial pressure is this.
What is low?
Covering the nasopharynx during swallowing is the function of this.
What is the soft palate?
Most cartilage in the respiratory tract serves this purpose.
What is keeping tubular structures open?
