Kidney and Urinary: How Does it Work?

How is the kidney and urinary system defined?

The kidney and urinary system acts as a filter for the body, eliminating toxins and wastes through urine. It transports this garbage via a network of tubes and ducts. These tubes connect to the blood vessels and digestive system of the body. Your urinary system contributes to the correct functioning of the rest of your body.

What Is the Difference Between the Kidney and Urinary Tract?

The urinary tract is one of the mechanisms via which our bodies eliminate waste. The kidneys are the section of the urinary tract responsible for producing urine (pee). Urine contains salts, poisons, and water, all of which filters from the blood. After the kidneys produce urine, it exits the body via the remainder of the urinary tract.

What Are the Kidney and Urinary Tract’s Components?

Individuals typically have two kidneys, they can live a full, healthy life with only one. The kidney locates behind the ribs, one on each side. Adult kidneys are approximately the size of a fist.

Each kidney comprises filtering units in an outer layer called the cortex. The medulla, the kidney’s central region, is lined by fan-shaped structures called pyramids. These discharge urine into calyxes, which are cup-shaped tubes.

Pee exits the kidneys via the calyxes and stores them in the bladder via the ureters (a muscular sac in the lower belly). When a person urinates, the urine departs the bladder and exits the body via another tube-like organ called the urethra, the male urethras terminate at the penis tip; female urethras terminate just above the vaginal opening.

What Function Do the Kidneys Perform?

The kidneys perform various functions, from filtering blood and producing urine to maintaining bone health and producing a hormone that regulates red blood cell development. All of these functions contribute to the kidneys’ critical role in keeping the body functioning normally. 

What function does the urinary system perform?

Your urinary system filters your blood to remove impurities. It flushes out excess water and salt, as well as poisons and other waste items. The urinary system’s various components execute a variety of functions, including the following:

  • Filtration of blood.
  • Distinguishing the toxins, you do not require from the nutrients you do require.
  • Urine storage and removal from the body.

How does the urinary system cleanse my blood?

Your kidneys are critical in the process of blood filtering. The urinary system operates as follows:

  • Each kidney receives blood via a network of small arteries.
  • Your kidneys separate poisons from nutrients in your blood.
  • Vitamins, minerals, nutrients, and proteins are all reintroduced into the bloodstream.
  • Urine and waste items pass via your ureters to reach your bladder. It is stored in your bladder until you use the toilet.
  • Urine exits the body via the urethra.

What are the kidney and urinary system’s components?

The urinary system comprises the kidneys, ureters, bladder, and urethra. They all function in unison to filter, store and eliminate bodily liquid waste. Each organ performs the following functions:

  • Kidneys: These organs operate continuously. They filter your blood and produce urine, which is excretes by your body. Two kidneys locate on either side of the rear of the abdomen, directly below the rib cage. Each kidney is roughly the size of your fist.
  • Ureters: These two small tubes located inside the pelvis transport urine from the kidneys to the bladder.
  • Bladder: The bladder stores urine until it is time to empty it (pee). It is hollow, made of muscle, and balloon-shaped. As your bladder fills, it expands. The majority of bladders have a capacity of up to 2 cups of urine. The urethra is the tube that drains pee from your bladder. 

What diseases and disorders are associated with the urinary system?

Numerous disorders can cause problems with the ureters, kidneys, bladder, or urethra. Infections, illnesses, and other health concerns might manifest at birth or develop as you age. Several common urinary diseases include the following:

  • Structural abnormalities: Occasionally, infants are born with birth disorders that impair how the urinary tract develops. These anomalies can result in a buildup of urine in the kidneys, which might result in infection. Bladder prolapse can occur later in life as a result of pregnancy or as women age. A prolapsed bladder either falls into the vaginal hole or hangs out of it. Occasionally, structural abnormalities require surgery to correct.
  • Kidney stones: These masses form as a result of waste items clumping together in the urine. Kidney stones or ureteral stones (kidney stones that pass through the ureter) can be extremely painful and obstruct urine flow. Your doctor may employ ultrasound (sound waves) to fragment the stones and make them easier to pass.

Other disorders are associated with the urinary system

  • Urination problems: A loss of bladder control, also known as urinary incontinence (leakage), results in a small amount of urine leaking. Women most frequently experience urinary incontinence, typically the following pregnancy or later in life. It can be made worse by coughing, laughing, sneezing, or jumping. Overactive bladder occurs when you experience frequent urges to urinate. Medications can assist in the treatment of certain disorders.
  • Obstruction of the urinary tract: Growths or malignant tumors in the abdomen can impair urine flow. In men, an enlarged prostate (also known as benign prostatic hyperplasia, or BPH) can obstruct the ureter, making urination more difficult. 
  • Chronic renal disease: high blood pressure and diabetes. Maintaining healthy blood pressure and blood sugar levels is critical for minimizing your chance of developing renal disease. A genetic ailment known as polycystic kidney disease results in the formation of fluid-filled cysts inside the kidneys. 
  • Interstitial cystitis: Also known as painful bladder syndrome, affects the bladder, causing inflammation (swelling and irritation). 

How prevalent are these disorders?

Bladder infections and urinary tract infections are the most prevalent urinary tract infections (UTIs). Women are more likely to have UTIs than men. Over 60% of women will develop a UTI during their lifetime.

Around half of women over the age of 65 suffer from urine incontinence, typically caused by strained muscles during pregnancy and childbirth. Kidney stones are also rather frequent, affecting around one in every ten persons.

How can I maintain a healthy urinary system?

The majority of urinary tract issues are preventable. However, you can attempt to maintain a healthy urinary system with adequate hygiene and a healthy lifestyle. To assist your urinary system is functioning properly, you can:

  • Consume plenty of water: Staying hydrated helps flush out your system and may help you avoid kidney stones and urinary tract infections. You might try drinking cranberry juice to help prevent a urinary tract infection. Cranberries contain compounds that may inhibit the growth of bacteria.
  • Consume a balanced diet: Consuming foods low in sodium and high in calcium may help prevent kidney stones.
  • After using the toilet, women should always wipe front to back. Proper wiping minimizes the chance of bacteria entering the vagina and developing a urinary tract infection (UTI).
  • After sex, you should empty your bladder: You should use the restroom if you are a female. Peeing can help eliminate bacteria and minimize your chances of developing a UTI.
  • Sex safely: Use a condom to protect yourself against sexually transmitted infections. However, caution should exercise while using spermicides, as they can promote the growth of germs.
  • Pelvic floor exercises, often known as Kegel exercises, can help avoid urine incontinence by strengthening the pelvic floor muscles.

When should I contact my physician if I believe I may have a urinary tract problem?

If you are having difficulty or pain while urinating, you should consult a physician, it could be an indication of an infection or another ailment. Consult your physician if you have:

  • Your pee contains blood.
  • The sensation of burning, pain, or difficulty urinating.
  • Pelvic, lower back, genital, or flank pain (the back and sides of your abdomen).
  • Inability to hold your urine or difficulties with urine leakage.
  • A sensation that something is protruding from your vagina.
