| Question | Answer |
|---|---|
| functional unit of the kidney | nephron |
| this part of the nephron dips into the renal medulla | loop of Henle |
| this organ filters blood and helps remove waste | kidney |
| the tube between the kidney and the bladder | ureter |
| this provides a storage tank for the urine | urinary bladder |
| these folds in the bladder stretch out as the bladder fills | rugae |
| this posterior pituitary hormone causes water to be reabsorbed in the kidney | antidiuretic hormone |
| a condition caused by the lack of antidiuretic hormone (ADH) | diabetes insipidus DI causes the urine to be very dilute |
| this tube inside the kidney reabsorbs water and concentrates the filtrate | collecting duct |
| a mass of twisting capillaries in the Bowman's capsule | glomerulus |
| this convoluted tubule comes before the loop of Henle | proximal convoluted tubule |
| protein in the urine | proteinuria |
| tube from the bladder to the outside | urethra |
| the inability to control urine | urinary incontinence |
| a drug or substance that increases urine volume | diuretic |
| low urine output | oliguria |
| a build up of urea and other waste products in the blood because of poor kidney function | uremia "urine in the blood" |
| double layer of epithelial cells that wrap around the glomerulus | Bowman's capsule (glomerular capsule) |
| the amount of fluid filtered by both kidneys is known as | Glomerular filtration rate (GFR) |
| a process that artificially filters blood as a kidney would | dialysis |
| The adrenal gland hormone that causes the body to retain sodium (and thus water) This causes an increase in blood pressure. | aldosterone |
| opening at the end of urethra | meatus |
| outer region of the kidney | renal cortex |
| inner region of the kidney | renal medulla |
| location of kidneys | retroperitoneal (behind the peritoneum) Kidneys are in the back, tucked under the bottom ribs. |
| the heart releases this hormone when blood pressure is elevated it causes the kidney to release sodium (and water) | Atrial natriuretic peptide (ANP) |
