Sir can you please explain why during ejection of blood from ventricles , there is increase in pressure even when volume is decreasing is decreasing continuously ?? Is there any reason for this or this is just an observation ??
@@madhorai2167 This expression isn’t correct - “pressure is increasing EVEN WHEN volume is decreasing….”. The correct expression is - “volume is decreasing BECAUSE pressure is increasing.” Remember, PV = constant??
@@VivekSirsPhysiology sir, the expression PV= constant cannot be applied here, due to the fact that no. Of moles( be it gas or any particle in blood ) are not constant. They are constantly decreasing . PV = constant by Boyles law when the moles are kept constant. For example sir when we fill tyre with air in vehicle the volume of the tyre as well as the pressure increase because no. of moles are also increasing. Boyles law will not be followed in these conditions.
@ You don’t want to apply the law of Physics, and then you are giving example of physics. Anyway, the point is very very simple. Pressure increases -> blood is ejected out -> blood volume in the chamber decreases.

Wonderful lecture 😅😅❤
Rbc example immediately got reminded of Safety Measures of Nm transmission, sir amazing lecture, love to study the subject with your guidance ☺️

@@snehajeetchoudhury1319 Haan re…..kuch na kuch nayaa try karta rehta hoon.
Thank you so much sir
Sir apse bahat aacha se padha CVS pura maja aya sir

@ Ae bhai. Pressure increases -> blood is ejected out --> volume decreases. What’s the difficulty?
@ You don’t want to apply the law of Physics, and then you are giving example of physics. Anyway, the point is very very simple. Pressure increases -> blood is ejected out -> blood volume in the chamber decreases.
Volume is not controlling pressure. Pressure is controlling the volume.
Sir physiology me important topics for passing prof exam video please
