Across
- 6. functional units of the kidney that carry out all filtration and modification to produce urine; consist of renal corpuscles, proximal and distal convoluted tubules, and descending and ascending loops of Henle; drain into collecting ducts
- 7. extensions of the renal cortex into the renal medulla; separates the renal pyramids; contains blood vessels and connective tissues
- 10. medullary area of the renal pyramids where collecting ducts empty urine into the minor calyces
- 14. tortuous tubules receiving filtrate from Bowman’s capsule; most active part of the nephron in reabsorption and secretion
- 15. inner region of kidney containing the renal pyramids
- 16. cup-shaped sack lined by a simple squamous epithelium (parietal surface) and specialized cells called podocytes (visceral surface) that participate in the filtration process; receives the filtrate which then passes on to the PCTs
- 17. tuft of capillaries surrounded by Bowman’s capsule; filters the blood based on size
- 19. nephrons with loops of Henle that do not extend into the renal medulla
Down
- 1. portions of the nephron distal to the loop of Henle that receive hyposmotic filtrate from the loop of Henle and empty into collecting ducts
- 2. arteriole carrying blood from the glomerulus to the capillary beds around the convoluted tubules and loop of Henle; portion of the portal system
- 3. cup-like structures receiving urine from the collecting ducts where it passes on to the renal pelvis and ureter
- 4. outer part of kidney containing all of the nephrons; some nephrons have loops of Henle extending into the medulla
- 5. second capillary bed of the renal portal system; surround the proximal and distal convoluted tubules; associated with the vasa recta
- 8. six to eight cone-shaped tissues in the medulla of the kidney containing collecting ducts and the loops of Henle of juxtamedullary nephrons
- 9. recessed medial area of the kidney through which the renal artery, renal vein, ureters, lymphatics, and nerves pass
- 11. consists of the glomerulus and Bowman’s capsule
- 12. descending and ascending portions between the proximal and distal convoluted tubules; those of cortical nephrons do not extend into the medulla, whereas those of juxtamedullary nephrons do extend into the medulla
- 13. nephrons adjacent to the border of the cortex and medulla with loops of Henle that extend into the renal medulla
- 18. branches of the efferent arterioles that parallel the course of the loops of Henle and are continuous with the peritubular capillaries; with the glomerulus, form a portal system
