What is the overall exchange of gases between the atmosphere, blood and body cells called?
What is Respiration
100
This process is located in the lower Pons, and is responsible for the transmission signal that prevents the "Turn-Off" of the respiratory signal?
What is Apneustic Center
100
These receptors respond to changes in blood pressure, and are located in the Aortic and Carotid Sinuses?
What is Baroreceptors
100
What is the average resting Intra-Pleural Pressure, in the lung-thorax relationship?
-4 to -5 cmH2O
100
This well known neurotransmitter, produces bronchial smooth muscle contraction, vasodilation, and gladular secretions when stimulated?
What is Acetycholine
200
These branches of the respiratory passageway, are the conduit of tubes which range from large to small, not responsible for gas exchange?
What is Bronchi
200
These type of chemoreceptors are not as sensitive to changes in CO2 their counterpart receptor?
What is Peripheral Chemoreceptors
200
This area of the lung is least gravity dependent, and has the potential to promote perfusion but most often does not?
What is Zone 1
200
What element has a greater effect on the distribution of blood flow other than pressure?
What is Gravity
200
These fibers emerge from the thoracic spinal medulla, and are referred to as adrenergic terminals?
What is Sympathetic Efferent Fibers
300
This term is considered the "Superficial Level" of respiration, where the exchange of respiratory gases between the lungs and blood occur?
What is External Respiration
300
Located in the upper Pons of the respiratory system, aids in the sending signals to the Medulla which acts to "Turn-Off" inspiration?
What is Pontine Respiratory Center
300
These type receptors located within the lung parenchyma, stimulate a "Shallow Breathing" pattern response?
What is Juxta Capillary Receptors, aka "J" Receptors
300
This is the portion of total ventilation that does not undergo gas exchange with the pulmonary system?
What is Deadspace Ventilation
300
This adrenergic receptor's action is principally excitatory and causes constriction of bronchial smooth muscle and increased mucous formation in the bronchial tree?
What is Alpha Receptors
400
These type cells are where the main site of gas exchange takes place?
What is Type I Alveolar Cells
400
Located on the ventral surfaces of the Medulla, this chemoreceptor is not as sensitive to changes in PO2?
What is Central Chemoreceptors
400
This type of reflex controls the "Depth" of inspiration, during marked inflation?
What is Hering-Breuer Reflex
400
A famous scientist stated that, pressure inside a spherical structure is directly proportional to tension within the wall of the sphere, but inversely proportional to that sphere's radius?
What is LaPlace's Law
400
What is the Beta 1 action response upon stimulation from Beta receptors, that increases within the heart?
What is contraction
500
These type cells sometimes called "Dust Cells", located in the alveolar walls are one of the lung defenses against foreign debris and particulates?
What is Type III Alveolar Cells
500
Integrated in the spinal cord, this system is principally involved in adjusting the pattern of breathing and "Strength" of muscle contraction, according to the mechanical state of the lungs and controls ?
What is Gamma-Efferent System
500
Distribution of pulmonary perfusion is dependent on these 3 factors?
What is Gravity, CO, PVR
500
What is the term that describes the amount of air moved in and out of the lungs per unit of time?
