Aveoli
|
where 02 and C02 exchange takes place between.
|
|
|
surfactant
|
keeps aveoli from collapsing
|
|
|
attalactasis
|
collapse of aveoli
|
|
|
plural cavity
|
2 layers that protect the lungs
1)viseral plura (inner layer) 2)plerital plura (outter layer) |
|
|
harring brewer reflex
|
expiration stress receptors lungs signal respiratory centers via the vagus to stop inspiration
|
|
|
kemoreceptors
|
normal neroregulatory control of ventilation.
|
|
|
central kemoreceptors
|
located on serfice of medula ablengada detect changes in ph of cerebral spinal fluid if medula fails pons will take over
|
|
|
prerephrial kemoreceptors
|
located in arch of aortic body and common carotid artery detect variation of 02 in arterial blood in addtion to changes in arterial carbon dioxide and ph levels
|
|
|

hemoglobin
|
cell in red blood cells carries 02 and C02 through out body
