|
||||
| 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
🗑
|
||||
