| Indentation located in the medially concave region of the kidney. | Hilum |
| Functional unit of kidney. | Nephrons |
| Outer region of the kidney - urine manufacturing facility. | Renal Cortex |
| Inner region of the kidney - urine collecting facility. | Renal Medulla |
| Collecting tubules that organize themselves into triangular wedges. | Medullary Pyramids |
| Cells that measure blood pressure. | Juxtaglomerular Apparatus |
| Cup that collects filtrate from glomerulus | Bowman's Capsule |
| Two slender tubes that transport urine formed by the kidneys. | Ureters |

| Substance promoting the formation and excretion of urine. | Diuretic |
| Stimulates kidneys to reabsorb more water. | Antidiuretic Hormone |
| Decreases sodium by triggering urine production. | Atrial Natriuretic Hormone |
