Renal system, in humans, the organ system that includes the kidneys, where urine is produced, and the ureters, bladder, and urethra for the passage, storage, and discharge of urine.

In many respects, the human excretory or urinary system resembles that of other mammalian species, but has its own unique structural and functional characteristics. Conditions

Emphasize the elimination function of the system. The kidneys, however, both secrete and actively retain in the body certain substances that are just as crucial to survival as those that are eliminated.

The system contains two kidneys, which control the electrolyte composition of the blood and eliminate dissolved waste products and excess amounts of other substances from the blood; these latter substances are excreted in the urine, which passes from the kidneys to the bladder via two thin muscular tubes called ureters. The bladder is a bag that holds urine until it is eliminated through the urethra.

Kidneys are bean-shaped, reddish-brown paired organs, concave on one long side and convex on the opposite. They are usually located high in the abdominal cavity and along its back wall, lying on either side of the spinal column between the levels of the 12th thoracic and third lumbar vertebrae, and outside the peritoneum, the membrane that lines the abdomen.

The long axes of the kidneys are aligned with the axis of the body, but the upper end of each kidney (hemi) slopes slightly inward toward the spine (spinal column). In the middle of the medial concave border is a deep vertical cleft, the hilus, which leads to a cavity within the kidney known as the renal (renal) sinus. The hilus is the entry and exit point of the renal arteries and veins, lymphatic vessels, nerves, and the extended superior extension of the ureter. The urinary tract is the body’s drainage system for removing urine, which consists of waste and extracts. liquid. For normal urination to occur, all parts of the body in the urinary tract must work together, and in the correct order.

Ureter, Bladder And Urethra Histology: Video

Kidneys. Two bean-shaped organs, each the size of a fist. They are located just below the ribcage, one on each side of the spine. Each day, your kidneys filter about 120 to 150 liters of blood to remove waste and balance fluids. This process produces about 1 to 2 liters of urine per day.

Ureters. Thin muscular tubes that connect your kidneys to the bladder and carry urine to the bladder.

Bladders. A hollow, muscular, balloon-shaped organ that expands as it fills with urine. The bladder is located in your pelvis between your hip bones. A normal bladder acts as a reservoir. It can hold 1.5 to 2 cups of urine. Although you can’t control how your kidneys work, you can control when to empty your bladder. Emptying the bladder is known as urination.

Urethra. A tube located at the base of the bladder that allows urine to leave the body during urination.

View full size image All parts of the urinary tract – the kidneys, ureters, bladder and urethra – must work together to urinate normally.

The urinary tract includes two sets of muscles that work together as a sphincter, closing the urethra to keep urine in the bladder between your trips to the bathroom.

To urinate, your brain signals the sphincters to relax. It then signals the muscle wall of the bladder to tighten, forcing urine through the urethra and out of the bladder.

How often you need to urinate depends on how quickly your kidneys produce urine to fill your bladder and how much urine your bladder can comfortably hold. The bladder wall muscles remain relaxed as the bladder fills with urine, and the sphincter muscles remain contracted to keep urine in the bladder. As your bladder fills, signals sent to your brain tell you to find the toilet soon.

The urinary tract is important because it filters waste and excess fluid from the bloodstream and removes them from the body.

The amount of urine you produce depends on many factors, such as the amount of fluid and food you consume and the amount of fluid you lose through sweating and breathing. Certain medications, medical conditions, and types of food can also affect the amount of urine you produce. Children produce less urine than adults.

Drink plenty of fluids, especially water. If you’re healthy, try to drink six to eight 8-ounce glasses of fluid each day. You may need to drink more if you have kidney or bladder stones. At least half of your fluid intake should be water. You may need to drink less water if you have certain conditions, such as kidney failure or heart disease. Ask your healthcare provider how much fluid is healthy for you.

Keep your bowels regular. Regular bowel movements are important for the health of your bladder. You can promote both bowel health and bladder health

Urinary Tract Obstruction

Go whenever you need to. People often hold their urine because it is not a good time to go to the bathroom. However, holding urine for too long can weaken the muscles of the bladder and make it difficult to empty the bladder completely. Urine left in your bladder can allow bacteria to grow and make it more likely that you will develop a urinary tract infection (UTI).

Develop healthy bathroom habits. Take enough time to empty your bladder completely when you urinate – don’t rush. Urinate after sex to flush out any bacteria that may have entered the urethra during sex. Clean the genital area before and after sex. If you are a woman, wipe from front to back, especially after a bowel movement, to prevent bacteria from entering the urethra.

Stay in tune with your body. Pay attention to how often you feel the need to urinate. Note if you need to urinate more often than usual, if your urine is leaking, if it becomes more difficult for you to start urinating, or if you feel that you cannot empty your bladder completely. These changes can be early signs of various problems with the urinary tract. Talk to your healthcare provider if you notice any of these signs. You may be able to prevent the condition from becoming more severe if you get help early.

Do exercises for the pelvic floor muscles. Pelvic floor exercises, also called Kegel exercises, can keep the pelvic floor muscles strong and maintain healthy bladder and bowel function. Both men and women can benefit from pelvic floor muscle exercises.

Functions Of The Urinary System

Including lean proteins, whole grains, high-fiber breads, nuts, fruits, and vegetables in your diet plan can maintain urinary tract health by promoting regular bowel movements.

It conducts and supports clinical trials for many diseases and conditions, including urological diseases. Research seeks to find new ways to prevent, detect or treat disease and improve quality of life.

Urinary System: Learn Definition, Properties And Facts

The urinary system consists of two kidneys, two ureters, bladder and urethra. The kidneys themselves perform the functions just described and produce urine in the process, while other organs of the urinary system provide temporary reservoirs for urine or serve as transport channels for its transfer from one part of the body to another.

The kidneys, which keep our internal fluids clean and stable, are perfect examples of homeostatic organs.

The urethra is a thin-walled tube that carries urine by peristalsis from the bladder to the outside of the body.

Every day, the kidneys filter gallons of fluid from the bloodstream. Normal physiology that takes place
