respiratory system

Quiz yourself by thinking what should be in each of the black spaces below before clicking on it to display the answer.

PO2 is   partial pressure of oxygen  
PCO2   partial pressure of Carbon Dioxide  
air on the arterial side contains much higher   PO2  
air on the arterial side contains much lower   PCO2  
Higher PO2 and PCO2 allow for oxygen to   diffuse into the capillary  
Higher PO2 and PCO2 allow carbon dioxide to   diffuse out of capillary, after which it is exhaled  
P is   partial pressure of a gas  
Tissue PO2 stays at approximately   40 mm Hg  
Hg is   mercury  
when not breathing pressure inside the lungs is same or different   same  
atmospheric pressure in   760 mm HG  
PV stands for   pressure and volume  
if lung pressure goes up volume goes....   down  
if lung pressure goes down, volume goes   up  
the pressure within the lungs drops .... mm HG during   inspiration  
during inspiration mm HG is   758  
the diaphragm comes up or drops down during inspiration   drops down  
Type ii alveolar cells secretee   lipoprotein  
lipoprotein substances is called   surfactant  
are surfactants a dry or oily substances   oily  
inside the alveoli,water tension does what   pulls inward on the alveolus  
why does water tension pull inwards on the alveolus   it is trying to collapse it  
...... breaks surface tension   surfactant  
why is it important to have surfactant   breaks surface tension to prevent collapse of the alveoli  
fetal lung produce very little   surfactant  
when born premature the lung   are difficult to expand and alveoli may collapse due to surface tension  
during respiratory distress syndrome what can be inserted in the lung   artificial surfactant  
In the brain stem, what contains respiratory centers to control breathing   pons & medulla oblongata  
what controls the rate of breathing   pons and medulla oblongata  
what 2 nerves control over breathing   phrenic & vagus  
diaphragm contracts via the   phrenic nerve  
sensory information from the lungs travels back to the brain via   vagus nerve  
what nerve tells the brain houw stretched the lung are and not to over stretch them   vagus nerve  
carbon dioxide is an   acid  
the higher the acidity the .... the ph   lower  
can receptors in the brain detect blood chemistry changes in breathing   yes  
the receptors in the brain that detect the changes in blood chemistry that affect breathing are called   central chemoreceptors  
ph will go up or down as PCO2 increases   down  
if ph drops below 7.4 this change is detected in the medulla oblongata, true or false   true  
what is detected in the medulla oblongata   changes in ph levels  
what causes an increase in respiration   ph drop below 7.4  
Receptors in the arota and carotid arteries detect changes in   oxygen concentration  
receptors in the aorta are called   aortic bodies  
receptors in the carotid ateries are called   carotid bodies  
what receptors send sensory information   arotic and carotid bodies  
sensory information is sent via what nerve   vagus and glossopharyngeal nerve  
the vegus and glossopharyngeal nerves send information to the   medulla oblongata  
low oxygen will trigger stimulation of ........   aorta and carotid receptors  
when low oxygen trigger stimulation of receptors this will   increase respiration  
Tidal volume   amount of air moved during a breath 500ml  
inspiration reserve volume   additional inspiration lung volume not used at rest 3000ml  
expiratory reserve volume   additional expiration lung volume not used at rest 1100ml  
residual volume (dead space)   set amount of air in lungs after maximum expiration 1200ml  
vital capacity   maximum tidal volume... max amount of air 4600ml  
total lung capacity   5800ml  
vital capacity is equal to   inspiration reserve + tidal volume + expiratory reserve volune  
total lung capacity is equal to   Inspiratory reserve + tidal volume + expiratory reserve volume + residual volume (dead space) aq  
hemoglobin saturation is   amount of oxygen bound to hemoglobin  
what affect hemoglobin saturation   PCO2, ph and temperature  
an increased PCO2 causes more dissociation of   oxygen from hemaglobin  
as ph decreases, hemoglobin saturation   decreases  
an increase in PCO2 causes   decrease in ph  
a decrease in ph causes   more oxygen to dissociate  
ph is dependent on more than just   CO2  
is hemoglobin saturation inversely proportional to temperature   yes  
increased tempurature is degreased   hemoglobin saturation  
body temp in celius   37-38  
asthma is a condition of what   trachea and bronchi lumen  
what happens when you have asthma   inflammation and mucous production, muscle contraction and lumen decreases in size  
emphysema is a condition of   alveolar walls rupture, creating larger spaces but less surface area for gas exchanges  
emphysema increases surface area for gas exchange   false  
what reduces elasticity of lung, resulting in difficulty exhaling   emphysema
