(Answers)
1 Ans⇒ Sodium Bicarbonale is added at
the time of setting up the experiment –
since calcium carbonate is liable to be precipitated it the
calcium & bicarborale are kept long together.
Q.4. Ans - use of Ringer's Solution -
- It is used for maintenance of these ions or to correct
their deficits
- It is used to rapidly restore circulating Blood volumne .
- continuous response the organ or Increase the energy
Q.7 Ans – contractility
-
• Contractility represents the innate ability of the heart
muscle to contract .
contractivity can be defined as any increase in the force of
contraction that cannot be attributed to the frank .
Q 8 Ans⇒ Isotonicity -
