Peeing, this little thing that doesn't matter much effort
But it is supported by a "system"
This is, both familiar and unfamiliar
Urinary system
It consists of "four major sectors"
Pictured, from top to bottom: kidneys, ureters, bladder, urethra
7 * 24 hours of "business", everyone is indispensable

1. Kidneys - "Excretory Chief"
Main job responsibility: Generate urine
Produced by clearing blood circulation from the body through urine
Metabolites, waste products, poisons
I'm under the rib arch of your back
2.5 cm on either side of the midline of the spine
One on the left and one on the left, reddish brown, close to the posterior wall of the abdomen
Generally length 10-12 cm, width 5-7 cm, thickness 3-5 cm
It's about the size of a fist
Lords
Avoid overeating, not smoking, not drinking, and eating less junk food
It won't overload me, oh, I'm vulnerable,
Not suitable for too much stress
I am sick, and the little lord will often feel sore and swollen in his waist
Located on both sides of the spine, the moving waist does not alleviate symptoms
2. Ureter - urine transport "highway"
Main job responsibilities: Send urine to the bladder
The length of the transport section is about 22-30 cm
The upper kidneys are connected to the lower bladder
Normally, I have regular and rhythmic contractions and relaxations
However, when obstruction occurs, the frequency and amplitude of creeping are also temporarily increased
The little lord will have kidney colic, nausea and want to vomit
If the obstruction is too long
The urine secreted by the kidneys gradually decreases

Remember, ladies and gentlemen
Drinking more water can allow the crystalline substances in the urine to be discharged in time to reduce the formation of stones
I won't have "congestion"!
3. Bladder - urine storage warehouse
Main job responsibilities: Store urine
My shape, size, position, and thickness of the wall
It changes with the amount of urine
When 300 to 500 ml of urine is stored in the bladder of a healthy adult
There will be an urge to go to the toilet

If it is not excreted in time, the urine will continue to increase
When the alert value of 800 ml is reached
The "detrusor muscles" on the lining of the bladder will start to make you feel pain
If you don't pee, the urethral sphincter will open the floodgates!
Note that when you appear:
urinary frequency, urgency, dysuria, laborious urination,
Fine urine line, low urine output, incomplete urine, blood in the urine, urinary incontinence
Please go to the hospital immediately
4. Urethra - warehouse keeper
Main job responsibilities: Responsible for the release of urine
Although I am at the bottom, I am in charge of two passes
Starts inward from the bladder outlet and extends outward to the outer mouth
There is a difference between men and women!

The male urethra is as long and winding as a winding road
Divided into four segments:
Bladder neck, prostate, membrane, base of the penis
Usually pay attention to less alcohol, less sedentary,
Do not ride for a long time to reduce the incidence of prostatitis
Women's urethra is short, about 3-5 cm, and closer to the vagina
Prone to urinary tract infection and cystitis
Usually pay attention to washing with water and keep the vulva clean
Urine, a barometer of good health
How to tell if it's healthy:
Urine output
The total 24-hour total for a normal adult is 1000 ml to 2000 ml
Polyuria > 2500 ml per day should be treated for the primary disorder
Daily amount
Symptoms such as oliguria and anuria are serious life-threatening symptoms!
See a doctor in time!
color
The color of urine can reflect the health status of the body to a certain extent
If the urine is "colorful"
It could be that your body is "asking for help"...
