Final answer:
The statement is false; the renal and urinary systems, not the respiratory system, are primarily responsible for removing excess water, salt, acid, and other electrolytes from the plasma.
Step-by-step explanation:
The statement "The respiratory system removes excess water, salt, acid, and other electrolytes from the plasma" is False. While the respiratory system does play a role in removing waste from the body by expelling carbon dioxide, the primary systems responsible for the removal of excess water, salts, acids, and other electrolytes are the renal system and the urinary system. The kidneys filter the blood and help to maintain osmotic balance by excreting these substances through urine. Therefore, it's important to note that the body uses different systems to manage various types of waste and electrolyte regulation.
