| root word meaning "pertaining to the kidney" | renal |
| basin or collection area within the kidney | renal pelvis |
| What is the tube that transports urine from the kidney to the bladder? | Ureter |
| place where the ureter leaves the renal pelvis | ureteropelvic junction |
| space that hold urine; chalice or cup | calyx |
| the outside part of the kidney | cortex |
| center of the kidney | medulla |
| the structural and functioning unit of the kidney | nephron |
| basin in the kidney that collects urine from the calyx and drains it into the ureter | renal pelvis |
| collection of capillaries in the nephron that resembles a small ball of yarn | glomerulus |
| small tubes that make up the system by which the urine flows through the nephron | tubules |
| small tubes that make up the system by which the urine flows through the nephron | tubules |
| section of tubes closest to the glomerulus | proximal convoluted tubule |
| loop that connects the proximal tubule with the distal tubule | Loop of Henle |
| Tube that connects and carries urine from the tubules to the calyx of the kidney | collecting duck |
| process in which the glomerulus acts as a filter to begin the process of removing the by-products of body metabolism from the blood | glomerular filtration |
| process in the system of tubules by which certain products are eliminated and certain products are reabsorbed | tubular reabsorption and secretion |
