Across 1. Connective tissue surrounding the outside of the kidney 3. Hormone which causes vasoconstriction of efferent arterioles to increase blood pressure and stimulate release of aldosterone and ADH 5. The pressure caused by filtrate meeting resistance from the walls of the capsule, creating back pressure 7. Epithelial cup functioning as a sieve around the glomerulus 10. Type of nephron found on the surface of the cortex 15. Fissure on edge of kidney where the ureter and renal vein and artery leave the kidney 19. Capillaries from the efferent arterioles, which surround the tubular portion of the nephron 20. The pressure caused by concentration of proteins in the blood causing water to move back into the blood 23. Portion of the nephron where blood is filtered 24. Venules which form from the reuniting of peritubular capillaries, and eventually form the renal vein 26. Funnel which collects urine from the calyxes to send into ureter 27. Type of capillary found in the glomerulus 28. Chambers which collect urine from the pyramid 29. Arterioles which form from the reuniting of glomerular capillaries 30. Tube which carries urine from the bladder to outside the body

Down 1. Space between the layers of the glomerular capsule, leading to the PCT 2. Secreted by the heart to increase filtration to reduce blood volume 4. Capillary bed within the kidney 6. Bottom points of each pyramid which extend into a calyx 8. Outer layer of the kidney 9. The pressure caused by blood pressure forcing filtrate through capillary pores 11. Sac which functions to temporarily store urine 12. Type of nephron found deep in the cortex 13. Tubes which transfer urine from the kidney to the bladder 14. Functional unit of the kidney which filters blood and produces urine 16. Extensions of the renal cortex extending into the medulla, separating the renal pyramids 17. Portion of the nephron where filtrate passes 18. Hormone that stimulates RBC production 21. Arterioles which subdivide into a glomerulus 22. Collections of tubules which transport urine from the cortex toward the calyxes 25. Inner layer of the kidney
