Final answer:
The secondary dilulation of embalming fluid is a result of changes in electrolyte balance and body water volume, leading to intracellular edema, slowed circulation, and impaired urinary function, ultimately causing weakness.
Step-by-step explanation:
The secondary dilution of embalming fluid occurs due to a change in the balance of electrolytes and the volume of body water. Intracellular edema can result when there is a concentration of electrolytes within bodily fluids, mainly affecting sodium (Na) in the extracellular fluid or potassium (K) in the intracellular fluid, along with the acid radicals bicarbonate (HCO3) and chloride (Cl). This disruption leads to a variety of physiological impacts including the swelling of cells, which is the intracellular edema, slowed circulation, and impaired urinary function. As the body attempts to balance the concentration of electrolytes, there is either an elimination or retention of water, leading to the secondary dilution effect. This process has a significant impact on the individual's health, causing weakness and potentially other complications.
