Respiratory Anatomy
This is the primary muscle responsible for breathing, located below the lungs.
What is the diaphragm?
Amount of blood ejected with each beat, usually 60-100 mL.
What is stroke volume?
The active process including flattening of the diaphragm, decreased intrathoracic pressure, and thoracic expansion.
What is inspiration?
Fast and deep respirations, usually associated with DKA.
What are Kussmaul respirations?
The process by which oxygen is absorbed into the bloodstream and carbon dioxide is removed is called this.
What is respiration?
This is the smallest air passageway within the lungs where gas exchange occurs.
What are the alveoli?
Sympathetic ____ stimulation causes vasoconstriction.
What is alpha I?
Tidal volume x respiratory rate =
What is minute volume?
Severe, prolonged asthma attach that cannot be broken by repeated doses of bronchodilators.
What is status asthmaticus?
The ease with which the lungs stretch and expand.
What is compliance?
This part of the respiratory system is also known as the voice box and plays a key role in speech.

Rattling of mucus heard on auscultation of lungs.
Adequate blood volume, intact pulmonary capillaries, and efficient pumping of blood by the heart.
What are the components of lung perfusion?
The pressure contributed by a single gas.
What is partial pressure?
The structure that prevents the entry of liquids or solid food into the respiratory passageways during swallowing.
What is the epiglottis?
The effects of a beta I antagonist.
What are decreased heart rate and contractility.
ETCO2 waveform associated with obstructive pulmonary disease.
What is shark fin?
Effects of Guillain-Barre syndrome, ALS, and spinal cord traumas on the respiratory system.
What are issues with ventilation?
This gas has the most powerful effect on respiratory activity.
What is carbon dioxide?
These cells produce an oily secretion called surfactant.
What are septal cells?
Rate of impulse conduction.
What is dromotropy?
Increased temperature, CO2, and H+ ions on the oxyhemoglobin dissociation curve.
What is a right shift?
Pulmonary heart disease caused by pulmonary hypertension.
