Urinary system

Overview The urethra is a tube-like passage that allows urine (and semen, if applicable) to leave your body. What is a urethra? The urethra is the tube that lets urine leave your bladder and your body. If you were assigned male at birth, your urethra passes through your prostate and into your penis. If you were assigned female at birth, your urethra is much shorter. It runs from your bladder to open in front of your vagina. Anatomy Where is the urethra located? The urethra is a passageway located in your body’s pelvic region. The walls of the tube are thin and made up of The urethra has two different types of sphincters, or muscles that act as valves that open or close. There is an internal urethral sphincter, which is located at the point where the urethra leaves the bladder. There’s also an external urethral sphincter located in the pelvic floor. These muscles work together with the bladder to get urine out of your body. How long is the urethra? If you’re someone who’s been assigned female at birth, your urethra is about 1.5 inches (3 to 4 centimeters) long. If you’re someone who’s been assigned male at birth, your urethra is about 8 to 9 inches long (about 20 centimeters). In the anatomy typically called male, there are three parts to the urethra: • The prostatic urethra: The part of the urethra that carries seminal fluid through the prostate gland to produce the semen that will be ejaculated. • The membranous urethra: The short part of the urethra that transports fluid...

Female urinary system Your urinary system includes the kidneys, ureters, bladder and urethra. The urinary system removes waste from the body through urine. The kidneys are located toward the back of the upper abdomen. They filter waste and fluid from the blood and produce urine. Urine moves from the kidneys through narrow tubes to the bladder. These tubes are called the ureters. The bladder stores urine until it's time to urinate. Urine leaves the body through another small tube called the urethra. Male urinary system Your urinary system includes the kidneys, ureters, bladder and urethra. The urinary system removes waste from the body through urine. The kidneys are located toward the back of the upper abdomen. They filter waste and fluid from the blood and produce urine. Urine moves from the kidneys through narrow tubes to the bladder. These tubes are called the ureters. The bladder stores urine until it's time to urinate. Urine leaves the body through another small tube called the urethra. A ureteral obstruction is a blockage in one or both of the tubes (ureters) that carry urine from the kidneys to the bladder. Ureteral obstruction can be cured. However, if it's not treated, symptoms can quickly move from mild — pain, fever and infection — to severe — loss of kidney function, sepsis and death. Symptoms Ureteral obstruction might have no signs or symptoms. Signs and symptoms depend on where the obstruction occurs, whether it's partial or complete, how quickly it develops,...

This amount varies according to fluid intake and kidney function. Structure [ ] The urinary system refers to the structures that produce and transport urine to the point of excretion. In the human urinary system there are two kidneys that are located between the dorsal body wall and parietal peritoneum on both the left and right sides. The formation of urine begins within the functional unit of the kidney, the nephrons. Urine then flows through the nephrons, through a system of converging tubules called c...

It also plays a crucial role in water homeostasis, electrolyte and acid-base balance, and red blood cell production.The human urinary tract is comprised of two kidneys, two ureters, one bladder, two sphincters, and one urethra. The Urinary System How Does the Urinary System Work? How the urinary system works is relatively simple, although the supplementary roles of the kidneys can be complex. Blood is transported to the kidneys via the renal artery. A system of filtration units within the kidney regulates levels of dilution (water), salts and other small The passing of urine is known as micturition or urination. The urinary system is split into the upper and lower urinary tract. The former consists of the kidneys and ureters, the latter of the bladder and urethra. Urinary System Anatomy How much urine is expelled depends on various factors: the ratio of waste pr...

The urinary system, also known as the renal system, produces, stores and eliminates urine, the fluid waste excreted by the kidneys. The kidneys make urine by filtering wastes and extra water from blood. Urine travels from the kidneys through two thin tubes called ureters and fills the bladder. When the bladder is full, a person urinates through the urethra to eliminate the waste. The urinary system is susceptible to a variety of infections and other problems, including blockages and injuries. These can be treated by a urologist or another health care professional who specializes in the renal system. Description of the urinary system The urinary system works with the lungs, skin and intestines to maintain the balance of chemicals and water in the body. Adults eliminate about 27 to 68 fluid ounces (800 to 2,000 milliliters) per day based on typical daily fluid intake of 68 ounces (2 liters), The primary organs of the urinary system are the kidneys, which are bean-shaped organs that are located just below the rib cage in the middle of the back. The kidneys remove urea — waste product formed by the breakdown of proteins — from the blood through small filtering units called nephrons, according to the From the kidneys, urine travels down two thin tubes, called ureters, to the bladder. The ureters are about 8 to 10 inches long (20 to 25 centimeters), according to the Cleveland Clinic. Muscles in the ureter walls continuously tighten and relax to force urine away from the kidneys,...

The urinary system contains the kidneys, bladder, ureters, and urethra. These organs work together primarily to create, store and eliminate waste, namely urine. In order to function properly, the human body extracts nutrients from food and uses them to produce energy and repair damages. Once food has been broken down and the body has retrieved what it needs, waste products stay behind in the bowel and the blood until they are removed via the urinary system. Successfully ridding the body of waste is essential to maintaining optimal health. That's the job of the urinary system: Its construction is relatively simple, but the processes that occur within it are complex and vital to health and well-being. What the Urinary System Does The principle function of the urinary system is to remove liquid and gaseous wastes from the body. In order to do this, the urinary system performs three main tasks: • Excretion: Excretion involves the removal of liquid and gaseous wastes from the blood. Often, dissolved solids are present in the blood and are also removed through excretion. • Secretion: Secretion occurs through the production of urine. Once wastes have been removed from the blood, they are released (secreted) through urine. • Elimination: Elimination occurs when urine moves from the bladder to the urethra and then out of the body. How the Urinary System Functions The urinary system is comprised of two kidneys, two ureters, two sphincter muscles, the bladder and the urethra. Each of...
