Across
- 4. during severe dehydration, levels of this hormone increase.
- 5. this is where most water, glucose, amino acids, and needed ions are reabsorbed back into the blood.
- 7. its main job is to help regulate blood pressure and fluid balance through the RAAS system.
- 8. during dehydration, urine ___ decreases.
- 10. what process happens as filtrate travels through the nephron, allowing water and useful substances to return to the blood?
- 13. one way the kidneys help maintain homeostasis is by regulating ___ balance by adjusting how much is reabsorbed or excreted.
- 15. this is where the final water reabsorption occurs under the influence of ADH, further concentrating the urine.
- 16. what process removes wastes from the blood to begin urine formation?
- 18. this is where water is reabsorbed in the descending limb, while salts (Na and Cl) are reabsorbed in the ascending limb, helping concentrate the filtrate.
- 19. the kidneys maintain this to keep the body's internal environment stable.
Down
- 1. this is where blood is filtered, and water, ions, glucose, amino acids, and wastes enter the filtrate.
- 2. one way the kidneys help maintain homeostasis is by maintaining blood __ by extracting hydrogen ions and conserving bicarbonate.
- 3. the body produces ___ to help control RBC production and activate vitamin D for calcium regulation.
- 6. patients with impaired kidney function may have problems with blood pressure and _____ balance.
- 7. during dehydration, water ___ by the kidneys increases.
- 9. during dehydration, urine becomes more ___.
- 10. hormone released by the kidneys when the blood pressure is low.
- 11. system that uses renin, angiotensin, and aldosterone to regulate blood pressure.
- 12. one way the kidneys help maintain homeostasis is by regulating body _____ levels, such as sodium, potassium, and calcium.
- 14. this is where additional ions and wastes are secreted into the filtrate, while more salts and water may be reabsorbed as needed.
- 17. hormone that increases sodium and water retention to raise blood pressure.
