The urinary system of the human body is also called the renal system or urinary tract. It mainly contains the ureters, urethra, bladder, and kidneys. The urinary system removes impurities, regulates electrolytes, and metabolites levels, and regulates blood pressure and pressure. The urinary system produces urine in the body. The kidneys filter the blood and make urine. The urine then reaches the bladder after passing through the ureters. Urine is then stored in the bladder before it flows through the urethra during urination. The urinary system of men and women is exactly the same, except for the length of the urethra. The average amount of urine excreted in the human body is 800-2000 ml, but this amount may vary depending on the fluid intake.
Urinary System Performance
After absorbing all the nutrients found in all foods and liquids, our body stores the required amount of energy and residual waste called urea in the intestines and blood of the human body. The body's urinary system removes urea from the human body and helps keep minerals and water in balance. After all the protein is absorbed by urea it is made in the kidneys. Here the urine is different from other substances. There are other important kidney functions such as controlling blood pressure etc. Kidneys also test for acid-base stability. After this urine is stored in the bladder until it is excreted through the urethra.
Urinary system function
The main functions of the human urinary system are
Control blood volume and composition (eg sodium, potassium, and calcium)
It contributes to the production of red blood cells by the kidneys.
Control the pH of blood homeostasis.
It helps to synthesize calcitriol (an active form of Vitamin D).
Control blood pressure.
It stores waste (especially urea and uric acid) before other products are eliminated from the body.
Components of the Urinary System
Kidneys
The human body is made up of two kidneys. These organs are dark brown in color. They are located under the ribs and in the middle of the back. Their main functions are
They eliminate waste and chemicals from the human body.
Stabilize the body fluids of the human body.
They stabilize many different electrolytes.
They bring hormones to control the blood pressure of the human body.
Control the production of red blood cells by releasing hormones.
It regulates the amount of calcium and phosphorus in the human body which are essential for bone health
Nephrons are filters that release urea into the bloodstream of the kidneys. These nephrons contain glomerulus (a ball made up of small capillaries) and a small tube called the renal tubule.
Ureters
Urine flows from the kidneys to the bladder through these tiny tubes. Tightness and relaxation of the muscles in the walls of the ureter forces the urine to go down, away from the kidneys and close to the other. If the ureters do not work properly and the urine in the ureters does not progress, it can cause kidney disease. A certain amount of urine is excreted regularly from the ureters to the bladder hum after 10 to 15 seconds.
Bladder
Another empty organ placed under the lower abdomen. It is a triangular shape. It stands with the help of lines connected to the pelvic bones and other organs as well. The bladder walls grow and reach the end of urine. Their proliferation and contraction causes urine to pass out of the urethra. The average person can keep a list of urine for about 2 cups over a period of 2 to 5 hours.
Two sphincter muscles
These muscles are circular, and they are close to the bladder so that they do not leak..
Feelings Another
These sensations frighten the human body as they excrete urine in the bladder.
Urethra
This tube-shaped organ allows urine to escape from the human body. The bladder receives signals from the human brain and muscles that are strong enough to pass urine to the bladder. The Sphincter muscles receive a signal to the brain at the same time to drain urine from the bladder through the urethra. When this complete procedure is performed correctly, normal urination occurs.
