What are the two factors that are regulated to maintain fluid balance in the body?​

Quizplus · Accepted Answer

The regulation of ECF (extracellular fluid) volume and its osmolarity is crucial in maintaining fluid balance in the body. ECF volume is regulated through the balance between fluid intake and output, and the renal system plays a significant role in this process. Osmolarity is regulated by the presence of electrolytes in the ECF, primarily sodium ions. The body's complex feedback mechanisms continually regulate these two factors to maintain fluid balance. Option A, salt concentration and blood pressure, and option B, body temperature and blood pressure, are not directly related to fluid balance. Options C and D refer to ICF (intracellular fluid) factors, which are not directly involved in regulating overall fluid balance in the body.
