Blood enters the renal system through the [1] into the kidney. The blood eventually flows into the funtional unit of the kidney, the structures called [2], where filtration, secretion of waste, and reabsorption of essential nutrients, ions, and water occurs. After this structure the remaining filtrate waste (now called [3]) will travel down the [4] of the renal pyramid and out the renal papillae to the [5], which merge into the [6], which then merge into the [7]. The fluid then travels down the [8] into the [9], where it is temporarily stored until it’s time for elimination. During elimination, the urine flows from storage to the outside of the body through a tube called the [10].
