What is the function of dissolved salts in the plasma?

Dissolved salts in plasma, primarily electrolytes like sodium, potassium, calcium, and chloride, play crucial roles in maintaining fluid balance, regulating blood pressure, and facilitating nerve and muscle function. They help to maintain osmotic pressure, ensuring that cells remain properly hydrated. Additionally, these electrolytes are vital for the transmission of electrical signals in nerves and muscles, contributing to overall physiological processes.
