Question

Trace the path a molecule of water will travel from the renal artery to the toilet bowl. Indicate the blood vessels, Nephron structures, Kidney structures the water molecule will travel through.

Answer 1

Answer

Path for water molecule from renal artery :

1. Renal artery
2. Segmental artery
3. Interlobar artery
4. Arcuate artery
5. Interlobular artery
6. Afferent arteriole
7. Glomerlar capillaries
8. Bowman's capsule
9. Proximal convoluted tubule
10. Descending limb of Henle's loop
11. Ascending limb of Henle's loop
12. Distal convoluted tubule
13. Collecting duct
14. Renal papilla
15. Minor calyx
16. Major calyx
17. Renal pelvis
18. Ureters
19. Urinary bladder
20. Urethra
21. Urethral orifice Out of the body in toilet bowl

- The water molecule travels in blood through the renal artery and enters the kidney.
- It is filtered in glomerular capillaries and enters Bowman's capsule as filtrate.
- When filtrate enters terminal part of collecting duct is known as urine.
- From medullary region of kidney, urine enters renal papilla at the end of renal pyramid.
- Through the structures such as calyces and renal pelvis it runs through the tube called ureter into the bladder.
- Urethra transports urine out of the body.
