Hint: Urine is a transparent, straw coloured or pale yellow in colour watery fluid that is excreted through urethral opening. It is produced by the kidneys in the human body. It is slightly acidic in nature.

Complete answer:
First of all we will discuss what is urine.
Urine is a transparent, straw coloured or pale yellow in colour watery fluid that is excreted through urethral opening. It is produced by the kidneys in the human body. It is slightly acidic in nature.
Now let us discuss how micturition occurs.
Urine is formed by the nephrons and then it is carried to the urinary bladder through ureters.
It is stored right there until the signal (voluntary) is given by the central nervous system.
And then the urinary bladder is voided via the urethral opening.
Although the normal range of pH of urine is considered as 4.5-8.2.
Clinical importance:
The clinical importance of the pH is that slight change in the pH of the urine signifies the presence of some kind of infection .
In the presence of an infection there is a burning sensation produced and pain can also occur.
Also , slight change in colour of urine can also signify the presence of some underlying systemic condition.

The pH of the urine is towards the slightly acidic side and the average pH is 6.0.

Note: Kindly note the clinical importance of the pH discussed above. That is why it is important to know the normal range of pH. The range of pH depends upon the diet of the person, whether the diet is acidic or basic.
