Difference between Scala vestibuli, scala tympani and scala media

Scala vestibuli and scala tympani have perilymph with high Na

Scala media has endolymph which has high K (affected in Meineires disease)

Normal pressures in cardiac chambers (Just read)

R. atrium=min: 0 max: 8
R. Ventricle=min: 4 max:25
Pulmonary artery=min:9 max:25
Left atrium= min:2 max:12
Left ventricle=min: 9 max: 130
Aorta=min:70 max:130
Generally Left is greater than right
