How is the process to creating urine?
Do you know how
your urine is created? Urine is the result of our metabolism process. It is
created through excretion process of our body and processed in kidney and
excreted to outer body through urine’s excretion duct. The processes of
products urine consist of 3 main processes. There are filtration, reabsorb, and
the last is augmentation.
Filtration is
filter process to separating substances which still used by our body and
substances which unused again by our body. Filtration occurs in nephrones.
First, bloods from renal vena enter to kidney and then in nephrone, it is filtered.
The result of this process is prime urine, this urine has not proteins but
still contain amino acids (small protein). And then prime urine flowed to
bowman capsule.
From bowman
capsule, urine enters to proximal tubules. In this tubule will occur reabsorb
process. The substances that absorb by proximal tubules are substances that
still useful for our body, such as amino acids, glucoses, and minerals. The
result from reabsorb process is called secondary urine. Secondary urine will
enter to distal tubules for augmentation process. But before enter to distal
tubule, secondary urine through loop of henle. Here occurred absorb of water
and mineral salt (NaCl) again.
Then secondary
urine enters to the distal tubule. In this part occurs augmentation process, it
is added substances which useless for our body. For example H+,K+,NH3 ,
and creatinin. Now, urine will collected in collectives duct and then go to
pelvis and to go out from our body through ureter to urinary bladder and then
through urethra. And go out in urine shape.
The normal
urine contains of water, urea, ammonia, ureat acids, NaCl, and some drug
substances. We will feel like urinate when urine in our urinary bladder have
full. And you shouldn’t hold to urinate because it is the bad way and dangerous
for our body. The other excretion process like urine excretion is sweat
excretion. Urine and sweat excretion have relation in our body system.
