GENERAL HISTOLOGY

Detailed explanation-1: -The amount of water and solute reabsorbed is what primarily regulates blood volume. If blood volume is too low, more filtrate reabsorbs; if blood volume is too high, less filtrate reabsorbs. The kidney is also responsible for the secretion of erythropoietin.

Detailed explanation-2: -When blood volume increases, it expands your arteries and veins and leads to increased blood pressure. Hypervolemia usually occurs because your body is not able to regulate fluids properly due to impaired kidney or liver function.

Detailed explanation-3: -One way the the kidneys can directly control the volume of bodily fluids is by the amount of water excreted in the urine. Either the kidneys can conserve water by producing urine that is concentrated relative to plasma, or they can rid the body of excess water by producing urine that is dilute relative to plasma.

Detailed explanation-4: -Drink more water. Fluids increase blood volume and help prevent dehydration, both of which are important in treating hypotension.
