Can you trace the path taken by a molecule of urea from the time it is produced in the liver to the time it leaves the body in the urine?

Answer 1

Renal artery à afferent arteriole à glomerulus à Bowman's capsule à proximal tubule à loop of Henle à distal tubule à collecting duct --> renal pelvis --> ureter --> bladder --> urethra

Answer 2

from the blood, into the kidneys, into the NEPHRONS:

okay so the blood flows through capillaries called the GLOMERULUS where blood pressure squeezes it out into the the bowl the glomerius is in called BOWMAN's CAPSULE. through the proximal tubule, loop of henle, distal tubule, collecting duct into the RENAL PELVIS thorough the URETER to the BLADDER down through the URETHRA

Answer 3

Urea is made from ammonia filtered out of the blood by the neutrons in the kidney. As ammonia is a highly toxic substance to humans, and humans have moderate water supplies, it undergoes multiple chemical reactions to convert from ammonia to urea which is diluted to urine and excreted out of the urethra.

from the blood, into the kidneys--> afferent arteriole--> glomerulus--> glomerular Capsule--> proximal convulated tubule-->desending limb--> loop of henle--> ascending limb--> distal convulated tubule--> collecting duct--> renal papilla--> minor calyx--> major calyx--> renal pelvis--> uretopelvic junction (upj)--> ureter--> uretovesical junction (uvj)--> bladder--> and finally urethra and out it goes.
