Dialysis is the process of separating elements in a solution by diffusion across a semipermeable membrane (diffusive solute transport) down a concentration gradient. The herein picture shows you with simplified schematic of typical hemodialysis system in the principal process for removing the end-products of nitrogen metabolism (urea, creatinine, uric acid), and for repletion of the bicarbonate deficit of the metabolic acidosis associated with r…
The herein schematic diagrams the negative feedback system that is activated by hemorrhage. All of these effects (mentioned below) lead to controlled blood pressure. In this diagram, hemorrhage leads to decreased blood pressure, which in turn leads to increased reabsorption of fluid, increased constriction of blood vessels, increased renal conservation of fluid, and increased catecholamines and vasopressin. Because all of the consequences tend…
