The Relationship between CV and Respiratory Systems Flashcards
what causes enlargement of the right side of the heart
high blood pressure in the pulmonary blood vessels
usually caused by chronic lung disease
what does vascular haeomodynamic adaption correlate to
adaptive feedback
what encourages good blood flow
good V/Q ratio (match)
V=Ventilation
Q=Perfusion
is oxygen soluble in plama
not very
what happens to the blood oxygen that doesn’t dissolve in plasma
it is transported by haemoglobin
what increases the bloods ability to carry carbon dioxide
deoxygenation of the blood
oxygenation of blood does opposite effect
how saturated in haemoglobin in arterial blood
98.5% saturated
saturation of haemoglobin in venous blood
75% saturated
what happens when there is an increased affinity for oxygen by haeomoglobin
- more loading of O2
- less unloading
what happens when there is an decreased affinity for oxygen by haeomoglobin
- less loading of O2
- and more unloading
how does higher temperature effect o2 saturation
there is a decrease in affinity
how does lower temperature effect o2 saturation
there is in increase in affinity
how does increased ph affect o2 saturation
it increases affinity
how does lower pH affect O2 saturation
it decreases affinity
