Urine is formed by a specific structure known as the _(1). To begin this process,blood enters the renal corpuscle by way of the afferent arteriole and reaches the _(2)_of the nephron, which is a specialized capillary bed that acts like a strainer to filter outdissolved particles from the plasma. As fluid leaves the glomerulus, it enters _(3)_ and is now known as filtrate. Filtrate quickly moves into the next segment of the nephron, the renal tubule by enteringthe _(4)_, where 65% of all particles the body needs to keep are reabsorbed intoperitubular capillaries. Next, the filtrate moves to the _(5)_, where reabsorption is completed. In the_(6), water only is reabsorbed into the vasa recta while in the _(7)_, salt only is activelytransported into the medullary space. The last stop for the filtrate is the _(8), wheresecretion occurs. Here waste products can be secreted from the peritubular capillariesand become a component of urine. The last stop in the nephron is the _(9)_, where urine from multiple nephronsmerges together. This tube carries the urine to the inferior part of the pyramid known asthe _(10)_, where urine drips into a funnel shaped structure known as a _(11)Each calyx collects urine from one pyramid and transports the waste into thecenter of the kidney in an open area known as the _(12)_. This region directs urine outof the kidney via the _(13), which exits the hilum. From here, the ureters carry urine forstorage in the _(14)_before it will be released from the body by a final output tubeknown as the _(15)
