The process of the formation of Urine, from beginning to end

Urine formation process is a process that occurs in the human body in order to issue the remaining substances and are not needed anymore from within the body. Urine formation process became one of the important process that we need to know, for a number of conditions caused by everyday bad habits as well as some of the disease outside the system of the formation of urine can interfere with this process. Call it the habit of drinking water that is less than 8 glasses per day, a number of diseases such as high blood levels of uric acid that can trigger the formation of kidney stones and even diabetes can damage blood vessels in the kidneys. The entire process of formation of urine occur in the kidney and through a number of special processes that are entirely governed by certain parts on one's kidneys. For it in this article before we discuss the stages in the process of the formation of urine, we will present a bit of a discussion about the structure of the human kidney. Happy reading!

The kidneys, the organs are important in the process of the formation of Urine!
As already mentioned before, the entire process of formation of urine occurs in an organ in a medical term known as ren (kidney). Humans have two kidneys that are attached to the back wall of the abdomen, kidney bean shaped like a human with a length of approximately 10-12 cm, width approx 5-7 cm and is comprised of approximately 2.5 to 4 centimeters. If a person's kidneys are cut transversely then would appear to be two different sections called the cortex and Medulla of the kidney.

The renal cortex is the outer part of the kidney that is red-brown while the inner part of the kidney is called the medulla of the kidney that is lighter. In the kidney is composed of many microscopic once nefron which is the smallest part of the kidney that holds an important part of the whole process of the formation of urine. Every human kidney contains approximately 1 to 1 ½ million nefron and every nefron has elements of the blood vessels and also the epithelium (tissue that lines the organ plays a person). These important elements will work together in blood flow into and out of the kidneys and filter blood and urine that is ready to be ejected from the body.

In the kidney's blood will be brought in through the afferent arterioles and then will go into kapsula bowman and filtered or difiltrasi in the glomerulus (blood vessel structure that serves as the primary screening venue for blood that went into the kidneys). Next blood that qualify will exit through the arterioles and efferent pathways through the left vein will be removed from the kidneys, while the result of the filtration is done by the glomerulus will undergo a series of other processes in the formation of urine ranging from contortus proximal tubules, Henle Ansa (Curved Henle) and distal tubules contortus.

After that the filtration result had almost become this urine streamed into the coligentes tubules and eventually flowed into the papilla of kidney Medulla on the left then a minor calyx major calyx (and the whole of the last is part of the gatherer urine on the ends of the medulla of the kidney) until it came to the ureter. From the ureter urine streamed toward the bladder and the bladder if we stretched because of the increased volume of urine in it then it will be sent a signal to the brain so the urinary curiosity arises and urine will be excreted through the urethra.
Important stages in the process of the formation of Urine
After the last we read in brief description of kidney organ that plays an important role in the formation of urine, we will now begin the process of dealing with what happened in the kidney in the formation of human urine. The core of this entire process was filtration or filtering. As already mentioned earlier, the blood will be brought into the functional structure of the kidney the glomerulus through the arterioles, i.e. afferen. Pressure on the afferen arterioles are indeed high enough so that the liquid pushes blood into the glomerulus and lead the process of filtering occurs optimally at the glomerulus, but there is a barrier (barrier) that will keep the large molecules such as proteins and various other blood cells cannot penetrate in this screening process.

These large molecules will be halted and the blood will leave the glomerulus through the arterioles efferen, whereas the results of the glomerulus filtration will enter the renal tubules to undergo other processes. We need to know that the glomerulus filtrate is different with urine from both the volume and also the composition of the kidney tubules work because, from the proximal tubule contortus, Ansa Henle distal tubules to contortus process of formation of urine that occurs is reabsorbsi (the process of absorption of return) and also the eksresi process (spending on substance that the body is not required).

The cells in all the parts of the kidneys are already mentioned above will selectively absorb back the substance-a substance contained in the glomerulus filtrate, the process of absorption of return it will be tailored to the needs of the body will be the substance of such. The substance of food like glucose will be completely reabsorbed, whereas absorption of return electrolyte (inorganic salts) such as sodium, calcium, potassium, Chloride will be adjusted to the levels of each substance in the blood. For example if in excess of sodium content in plasma in the kidney tubules sodium will not be reabsorbed, 80% of sodium is absorbed in the proximal tubules contortus and water will follow suit.

Almost 99% of the water contained in the glomerulus filtrate will be reabsorbed by the tubules of the kidney before getting to the ureter. Of 170 liters of water contained in the glomerulus filtrate is formed for 24 hours, 168.5 litres will be reabsorbed so that only 1.5 liters per day that are issued in the form of urine. The process of absorption of return water conducted by the renal tubules is also influenced by the antidiuretik hormone secreted by the pituitary gland. After a series of urine formation process ranging from filtration, absorption of return up to urine excretion of diginjal then it will be expelled through the ureter and then accommodated in the bladder before it was issued.

So a string of information that we can share about the organ which acts and the stages in the process of the formation of urine in the human body. This process happens all the time in your life and as you can see depends and will adjust the overall condition of our body. For that we must keep the health condition of the body so as not to add to add to the burden on the kidneys in carrying out its work.

Healthy eating patterns, apply enough sugar and salt also drink at least 8 glasses each day. If you have other ailments such as high blood pressure or diabetes, konsumsilah medicines that already given by doctors and rutinlah do a check-up or control the disease you will be due to complications in the kidneys can strike you at anytime. Finally we wish our articles regarding organ which acts and the stages in the process of urine formation is useful to add insight into all of us.
