Explanation / Answer

31) The correct option is D. Increasing or decreasing blood volume.
Long-term regulation of blood pressure is primarily achieved by altering blood volume.
32)The correct option is B. Potassium.
The major cation in the intracellular fluid is potassium.
33) The correct option is C. Chloride.
The major anion is chloride in the extracellular fluid.
34) The correct option is C. Proximal convoluted tubule.
The proximal tubule is a major site for reabsorption in nephron.
