Final answer:
Increasing K+ and decreasing Ca2+ refers to altering nerve conduction.
Step-by-step explanation:
Increasing K+ and decreasing Ca2+ refers to altering nerve conduction.
Regulation of blood calcium concentrations is important for the generation of nerve impulses. If calcium levels get too low, membrane permeability to sodium increases, which can result in muscle spasms and convulsions. On the other hand, altering the concentration of K+ ions can affect the excitability of nerve function, neural transmission, and contractility of cardiac and skeletal muscle.
