A molecule of urea from the renal artery goes to:
- A branch of the renal artery
- A much smaller blood vessel
- The nephron
- Glomeruli vessels
- Proximal convoluted tubule (PCT)
- Thin descending limb of the loop of Henle
- Thin ascending limb of the loop of Henle
- Thick ascending limb
- Distal convoluted tubule (DCT)
- Collecting duct
- Renal calyx
- Renal pelvis
- Ureter
- Bladder
- Urethra
- Outside
A Urea's molecule to go to the outside first has to pass from the blood to the renal system. Form the renal artery, it goes to a branch of this one, and then to a smaller vessel till it arrives at thin and small blood vessels in the nephron.
The nephron is the functional unit of the kidney, and it has different parts:
- The glomeruli vessels are a group of small blood vessels together and are surrounded by the Bowman capsule.
- From the glomeruli, the urea passes to the proximal convoluted tubule (PCT). It reabsorbs water, glucose, amino acids, and sodium.
- From there, the molecule of urea continues traveling to the Henle loop, which has a thin descending part, a loop, and a thin ascending part.
- Then it goes to the thick ascending limb.
- From there, it goes to the distal convoluted duct (DCD).
- The DCD connects with the collecting duct, which collects the urine from other nephrons.
The nephron takes the urine to:
- The renal calyx, where we have minor calyxes that form the major calyx.
- The calyx takes the urea molecule to the renal pelvis.
- The renal pelvis leads the urine to the ureter.
- The ureter is a duct that connects the kidney with the bladder.
- The bladder storages the urine with the urea molecule.
- Lastly, the molecule passes through the urethra and goes to the exterior of our body.
To sum up, a urea molecule from the renal artery goes to the nephron. Then to the renal pelvis, the ureter to take the urine to the bladder, and lastly, the urethra.
