The components of the urinary tract; 2 kidney, 2 ureters, urinary bladder and urethra. The waste product of this process is urine, a concentrated solution containing water, urea a product of the breakdown of proteins, salts, amino acids, by products of hepatic bile, ammonia and any other substance that cannot be reabsorbed by the blood. Urine also contains urinary pigments, a colored blood product that gives urine its characteristic yellow color. The renal pelvis acts as a filter, collects the urine that flows from the calyces, leaves the kidneys through the ureters and reaches the urinary bladder. The bladder dilates as it is filled, when it is full, it sends an impulse to the brain and the muscular walls of the bladder contract and the sphincter
The kidneys are located in the posterior section of the retroperitoneal cavity and are small, dark red kidney-bean shaped organs in the lower part of the rib cage (Marieb, The Urinary System, 2015). They are undervalued organs considering how essential they are for the body’s ability to maintain homeostasis. The kidneys filter about 120-150 quarts of blood to produce about 1-2 quarts of urine each day (NIH, 2014). Blood initially enters the kidneys through the renal artery. It then flows into the segmental artery before moving into the interlobar artery. From the interlobar artery the filtrate enters the arcuate artery before branching into the cortical radiate artery, which feeds into the afferent arteriole, before passing into the glomerulus where it begins to filter out waste. The filtered waste is then collected by renal tubule. The tubules drain to collecting ducts and all of these components together makes up a small unit called a nephron. Each kidney has over a million nephrons (Marieb, Blood Supply/ Nephrons, 2015). They filter out wastes that run through different body systems via blood; the majority of that waste is nitrogenous wastes, toxins, excess fluids, electrolytes, and drugs. These waste products are eliminated as urine. While waste are removed vital enzymes, hormones, and water are returned
Kidneys play an important role in the unary tract. They are located on each side of the spine, just below the ribcage. Each kidney is connected to the bladder by ureters. The kidneys have many functions, but the most common functions are to clean waste, control chemicals, and regulate fluid in the body which makes up the urine. Urine collects in the kidney before entering the ureters and as time passes more materials are added. When calcium and oxalate or phosphates are combined in the kidney tiny stones are formed called nephrolithiasis, commonly known as kidney stones. These stones can be very painful and “increases risks for diabetes, high blood pressure, and osteoporosis” (Goldfarb, 2009). About ten percent of all people will have kidney stones in their lifetime. Kidney stones are most frequently found in white men over the age of forty, relatives of kidney stone patients, and people who have formerly had kidney stones.
During digestion, the body breaks down food into smaller molecules that could then be used by the body’s cells and tissues in order to perform functions. This starts off in the mouth with the physical movements of chewing and the chemical breakdown by saliva. Enzymes in the stomach break food down further after traveling from the mouth through the esophagus. The food from here then moves into the small intestine, where pancreatic juices and enzymes dissolve proteins, carbohydrates, and fibers, and bile from the liver breaks down fats into these small molecules. Any portion of the fibers or food that were unable to be broken down are passed from the small intestine to the large intestine, which is where the digestive tract transitions into the excretory tract, then the colon and out of the rectum. Any liquids that have been stripped of their nutrients by the body proceed from the stomach to the kidneys. In the kidneys, sodium ions (Na+), uric acid, and urea are exchanged with water, which moves urinary bladder and is excreted through the
Kidney Stone Removal Introduction Kidney stones emerge from the accumulation of material in the urine, which tends to clog the kidney urine drainage system. Usually, this material flows out of the urinary system along with the urine. However, over extended periods of time, this material forms larger masses which may result in blockage of the urinary tract. This blockage may predispose to infection, which is characterized by bleeding and relentless pain. It can eventually lead to kidney failure.
The urinary tract consists of two kidneys, to ureters, urethra, and the urinary bladder. The urinary system works to remove waste from the body, maintain homeostasis of water, blood pressure, and regulate the body’s pH levels. The kidneys regulate several important internal conditions by excreting substances out into the body. After urine has been produced in the kidneys it is then transported to the urinary bladder via the ureters. The urinary bladder then holds the urine until the body is ready for excretion through the urethra.
A urinary tract infection (UTI) is an infection of the urinary tract. The urinary tract is the body's drainage system for removing wastes and extra water. Urinary tract infections can have different names, depending on what part of the urinary tract is infected. The infection can include the bladder, kidneys, ureters, or the urethra. If the infection is in the bladder it is called “cystitis” or a bladder infection. If the infection is in the kidneys is it called “pyelonephritis” or a kidney infection? If the infection is in the urethra it is called “urethritis”. Most urinary tract infections are bladder infections. Infections in the ureters are very rare. Everyone is at risk of getting a UTI allowing bacteria to grow in the urine that stays
The urinary system has many different organs in order for it to work as a whole. Each organ does different functions. The urinary system consists of the two kidneys, the two ureters, the bladder, the two sphincter muscles, the nerves in the bladder, and the urethra. After your body takes what it needs from the food you eat waste products are then left behind in the blood. The urinary system works with the lungs, skin, and intestines to keep the chemicals and water in your body balanced. The urinary system removes urea from your body. Urea is made when the foods you eat that are high in protein are broken down in the body. Urea is then carried into the bloodstream to the kidneys by the renal arteries.
Hello everyone and welcome to the tour of Mr. Doe’s gastrointestinal tract. Today we will be catching a ride alongside the very unhealthy food he will be consuming in just a few minutes such as, a hamburger, French fries and a root beer. For the next few minutes, please take a moment to look at the images of each structure on the pamphlet which is located on the back of the seat in front of you. The digestive system consists of the digestive tract called alimentary canal which forms a continuous path from the mouth to the anus. I hope everyone is buckled in and excited to see the different structures within the digestive system located in Mr. Doe’s body today! Ladies and gentleman, please hold on tight as Mr. Doe takes a bite out of his hamburger in just a few seconds.
All play a role in removing waste from your body. Your kidneys filter waste from your blood and regulate the concentrations of many substances. Tubes called ureters carry urine from your kidneys to the bladder, where it’s store until it exits your body through the urethra.
Each kidney contains over one million microscopic filtering units called nephrons. Urea, along with salt, water and glucose is extracted from the blood in the kidney by a process called ultrafiltration. Blood that passes the top of the nephron is under high pressure, so fluid is forced through the sieve-like capillaries and into the capsule. This fluid is called the filtrate. It does not contain any blood cells or larger proteins, as they are too big to pass out of the capillaries and into the capsule. Much of what has been filtered out needs to be returned to the blood. They are too precious to lose and so the next process is called selective reabsorption.
The filtered blood leaves the kidney along the renal veins. The filtered waste products are excreted by the kidney as urine. A narrow tube called the ureter carries urine from the kidney to the bladder. From there the urine is excreted through a single tube, called the urethra. Kidney structure: If you cut a section through the kidney, three areas can be seen:
A urinary tract infection is a very common infection that can happen to anybody. A urinary tract infection usually occurs when bacteria enters the urethra and multiples in the urinary system. The Urinary tract includes the kidneys, the thin tubes that carry urine from the kidneys to the bladder (ureters), and the main tube that carries the urine from the bladder (urethra). Women, men, and children are all immune to this infection. Women have the highest chances of getting it. In the Urinary tract, the main links of the ureters help get rid of any bacteria that tries to enter the urine, and the bladder helps prevent urine from backing up into the kidneys.
Urinary Tract Infection, also known as UTI, occurs in two common locations, the bladder and kidneys. The kidneys are important organs that aid in filtering out waste products from blood and maintaining water distribution throughout the body. The waste products are filtered out via bladder, which is the reason of the bladder being the second site for the infection. A normal human being has two kidneys, one on left and right side, a bean shaped organ, and is located at the back of the abdomen. “Each kidney is about 11.5 cm long, 5-7.5 cm broad, 5 cm thick, and weight about 150 grams” (HealthInfoNet, Paragraph 2). Furthermore, a bacterium named Escherichia coli lives in both the kidneys and the GI tract. E. coli is part of the human body and produces
The kidneys are bean shaped organs that consist of very thin walled capillaries and large numbers of filtration units called nephrons. They are located both sides of the backbone and are at the same level as the stomach. Each kidney has an inner concave side which is the location of a depression where the renal artery enters and the renal vein and ureters exit the kidneys. In a general term, the kidneys are a filter that removes certain substances from the circulatory system as well as large quantities of water. Some of these substances are reabsorbed into the blood whilst others are transferred to different areas of the body where they will be excreted.
The large intestine 's main function is to transport food particles through the body and expel the indigestible parts at the other end, but it also collects waste from throughout the body. The typical brown colour of mammal waste is due to billirubin, a breakdown product of normal heme catabolism. The lower part of the large intestine also extracts any remaining usable water and then removes solid waste. At about 10 feet long in humans, it transports the wastes through the tubes to be excreted.
