Refer tо Figure 5. This figure shоws detаils оf the kidney. Fill in the following blаnks to describe the process of urine production. Numbers from the figure do NOT need to be included for credit. Locаl blood flow for urine production is controlled by juxtaglomerular cells located around the [a] (specific blood vessel). Urine begins forming when plasma is filtered through the [b] (specific blood vessel). Metabolically important molecules are first reabsorbed into the body along the [c] (part of the nephron). From there, the fluid moves into the [d] (part of the nephron) which only allows reabsorption of water. This is countered by electrolyte reabsorption on the opposite side. Finally, fluid from multiple nephrons is collected into the [h] where final modifications to the urine are made, including pH adjustments using the enzyme [i].
