WHAT IF? Kidney failure is often treated by hemodialysis, in which blood diverted out of the body is filteredand then allowed to flow on one side of a semipermeablemembrane. Fluid called dialysate flows in the oppositedirection on the other side of the membrane. In replacingthe reabsorption and secretion of solutes in a functionalkidney, the makeup of the starting dialysate is critical.What initial solute composition would work well?
In your own words:
Elucidate the fundamental challenges the aquatic vertebrates and terrestrial vertebrates face in osmoregulation and their strategies to overcome them. Emphasize the modifications of their osmoregulatory organs.

Osmoreceptors gain water and swell; ADH release is inhibited.arrow_forwardIf osmoregulatory hypotonic fish species are generally bony fish and osmoregulatory hypertonic fish species are generally soft and absorbent. Does it mean the reason for them being soft or bony from an evolutionary standpoint gives reason to why they are formed that way?
