Blood Supply And Lymphatics
The ureters receive their blood supply from multiple arterial branches. In the upper or abdominal ureter, the arterial branches stem from the renal and gonadal artery, abdominal aorta, and common iliac arteries. In the pelvic and distal ureter, the arterial branches come from the vesical and uterine arteries, which are branches of the internal iliac artery. The arterial supply will course along the ureter longitudinally creating a plexus of anastomosing vessels. This is of clinical significance because it allows for safe mobilization of the ureter during surgery when proper exposure from surrounding structures is crucial.
The venous and lymphatic drainage of the ureter mirrors that of the arterial supply. The lymphatic drainage is to the internal, external, and common iliac nodes. The lymphatic drainage of the left ureter is primarily to the left para-aortic lymph nodes while the drainage of the right ureter primarily drains to the right paracaval and interaortocaval lymph nodes.
What Are The Kidneys And Urinary Tract
The kidneys are a pair of organs on the left and right sides of the tummy . The kidneys have a number of important functions which include:
- Maintaining the body’s fluid balance.
- Clearing waste substances from the blood.
- Regulating blood pressure.
- Making certain hormones.
- Balancing the levels of certain chemicals in the blood.
The urinary tract is a series of tubes and storage vessels that take the urine produced by the kidneys from inside the body to the outside. This includes the ureters, bladder and urethra. The ureters take urine produced by the kidneys to the bladder. The bladder stores urine until it is ready to be passed out. The urethra forms the passage between the bladder and the outside world. In men, the urethra also carries sperm.
What Is The Path Of Urine Through The Urinary System
From the kidneys through the ureters to the bladder from there through the urethra to be expelled from the body.
Urine is formed after a process of glomerular filtration in the kidneys.
This urine is then conducted through the ureters, twin muscular tubes that connect the kidneys to the bladder, a storage chamber.
The bladder is a muscular chamber that expands as urine fills it.
From the bladder, a muscular tube, the urethra connects to the outside.
The urethra , an internal sphincter at the junction of the urethra and bladder, and an external sphincter comprising the pelvic floor muscles, keep the urine in the bladder till it is ready to expel the urine.
For urination, the bladder walls contract and the urethra and sphincter muscles relax, to allow urine to flow out from the urethra.
Urine is formed by thousands of nephrons present inside the paired kidneys and it is passed down the ureters, there from to the urinary bladder. Now how is it formed?
Urine is formed when the blood reaches the malpighian corpuscle that is composed of the Bowmans capsule and glomerulus. Here most of the blood plasma is filtered out into the Bowmans capsule.
Glomerular filtrate is taken down the proximal convoluted tubule . Most of the water, glucose and amino acids are reabsorbed here. Active as well as passive reabsorption occurs here.
The resulting fluid passes down the loop of Henle . Electrolytes like Na+ and K+ are reabsorbed here.

Ureter Structure And Function
The ureters are two tubes that are made out of smooth muscle and transitional epithelial tissues, which are a type of epithelial tissue that may either be columnar or squamous. Each kidney has its own ureter through which urine drains into.
Human urinary system: 1) Human urinary system. 2) Kidney. 3) Renal pelvis. 4) Ureter. 5) Urinary bladder. 6) Urethra . 7) Adrenal gland vessels. 8) Renal artery and vein. 9) Inferior vena cava. 10) Abdominal aorta. 11) Common iliac artery and vein with transparency. 12) Liver. 13) Large intestine. 14) Pelvis.
The ureters are long tubes that have a few points of constriction, where obstructions are more common. The ureters receive a blood supply from a few different major arteries including the renal and illiac artery derivatives, and have a relatively dense nerve supply as well.
Muscles in the walls of the ureters send the urine in small spurts into the bladder, in a process called peristalsis. After the urine enters the bladder from the ureters, small folds in the bladder mucosa act like valves to prevent the backward flow of the urine these are called the ureteral valves. The ureteral valves function similarly to the semilunar valves in the veins of the body, but are structurally different, consisting of transverse mucosal epithelial folds.

What Tube Carries Urine From The Bladder
Moreover, how is urine transported to the bladder?
ureter: These are two long, narrow ducts that carry urine from the kidneys to the urinary bladder. urinary bladder: An elastic, muscular sac situated in the pelvic cavity, into which urine from the kidneys is stored prior to disposal by urination. Urine enters the bladder via the ureters and exits via the urethra.
Likewise, how does the bladder and kidneys work together? Urea, together with water and other waste substances, forms the urine as it passes through the nephrons and down the renal tubules of the kidney. From the kidneys, urine travels down two thin tubes called ureters to the bladder. The bladder stores urine until you are ready to go to the bathroom to empty it.
Keeping this in consideration, what forces help propel urine from the renal pelvis to the urinary bladder?
Ureters are tube-like structures that connect the kidneys with the urinary bladder. Each ureter arises at the renal pelvis of a kidney and travels down through the abdomen to the urinary bladder. The walls of the ureter contain smooth muscle that can contract to push urine through the ureter by peristalsis.
Where is your bladder located in a female?
The urinary bladder is a muscular sac in the pelvis, just above and behind the pubic bone. When empty, the bladder is about the size and shape of a pear. Urine is made in the kidneys and travels down two tubes called ureters to the bladder.
What Structure’s Transport’s Urine Directly From The Kidneys To The Urinary Bladder
. In this manner, which urinary organ transports urine out of the body?
kidneys: two bean-shaped organs that filter waste from the blood and produce urine. ureters: two thin tubes that take pee from the kidney to the bladder. bladder: a sac that holds pee until it’s time to go to the bathroom. urethra: the tube that carries urine from the bladder out of the body when you pee.
Furthermore, what is the pathway of urine through the kidney? Urea, together with water and other waste substances, forms the urine as it passes through the nephrons and down the renal tubules of the kidney. From the kidneys, urine travels down two thin tubes called ureters to the bladder.
Beside above, what structure associated with the urinary system transports urine and sperm?
The opening of the urethra, the tube that transports semen and urine, is at the tip of the glans penis. The penis also contains a number of sensitive nerve endings. The body of the penis is cylindrical in shape and consists of three internal chambers.
What structure is the first to collect urine?
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 collecting ducts.

Where Are The Kidneys Located
The kidneys are located on either side of the body underneath the diaphragm near the lower back. Each kidney is connected to the bladder in the pelvis by ureters that drain the urine from the kidneys to the bladder. Urine stored in the bladder is excreted from the body through the urethra. Collectively, these structures make up what is called the urinary tract.

How Does The Urinary System Work
The urinary system’s function is to filter blood and create urine as a waste by-product. The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra.
The body takes nutrients from food and converts them to energy. After the body has taken the food components that it needs, waste products are left behind in the bowel and in the blood.
The kidney and urinary systems help the body to eliminate liquid waste called urea, and to keep chemicals, such as potassium and sodium, and water in balance. Urea is produced when foods containing protein, such as meat, poultry, and certain vegetables, are broken down in the body. Urea is carried in the bloodstream to the kidneys, where it is removed along with water and other wastes in the form of urine.
Other important functions of the kidneys include blood pressure regulation and the production of erythropoietin, which controls red blood cell production in the bone marrow. Kidneys also regulate the acid-base balance and conserve fluids.

Where Are The Kidneys And Urinary Tract Situated
The two kidneys lie to the sides of the upper tummy , behind the intestines and either side of the spine. Each kidney is about the size of a large orange but bean-shaped. The ureters descend through the abdomen, one from each kidney, into the pelvis. Here they enter the bladder. The urethra is the tube leading from the floor of the bladder to the outside. A woman’s urethra is much shorter than a man’s. This may be why women are more likely to have urinary tract infections, as germs have less far to travel to cause an infection. In a man the urethra passes through the prostate gland and then through the penis. It also has several other glands associated with it. See separate leaflet called The Male Reproductive System for more details.
How Many Times Pooping Is Normal

What Is Glomerulonephritis
Glomerulonephritis is a big word that refers to several diseases that cause kidney injury. That monstrous word takes its name from the glomeruli, the tiny filters the kidneys use to clean your blood of waste.
These diseases are divided into two types: acute and chronic. Acute kidney injury comes on suddenly, and can be caused by throat and skin infections, as well as other disorders. It may get better all by itself, but it may also cause your kidneys to stop working without proper medical treatment. There are several symptoms of acute glomerulonephritis:
- Less frequent urination

What Is The Urinary Tract
The urinary tract is the bodys drainage system for removing urine, which is made up of wastes and extra fluid. For normal urination to occur, all body parts in the urinary tract need to work together, and in the correct order.
Kidneys. Two bean-shaped organs, each about the size of a fist. They are located just below your rib cage, one on each side of your spine. Every day, your kidneys filter about 120 to 150 quarts of blood to remove wastes and balance fluids. This process produces about 1 to 2 quarts of urine per day.
Ureters. Thin tubes of muscle that connect your kidneys to your bladder and carry urine to the bladder.
Bladder. A hollow, muscular, balloon-shaped organ that expands as it fills with urine. The bladder sits in your pelvis between your hip bones. A normal bladder acts like a reservoir. It can hold 1.5 to 2 cups of urine. Although you do not control how your kidneys function, you can control when to empty your bladder. Bladder emptying is known as urination.
Urethra. A tube located at the bottom of the bladder that allows urine to exit the body during urination.
The urinary tract includes two sets of muscles that work together as a sphincter, closing off the urethra to keep urine in the bladder between your trips to the bathroom.

Bacteria Can Be Sequenced From Urinary Stones
In 2015, we published a microbial study of five kidney stones along with both upper tract urine and bladder urine obtained during the stone removal procedures . The patients ages were between 12 and 29 years four of them had documented CaOx stones .
In each stone, 16S rRNA gene sequencing identified multiple bacteria. Some of these bacteria were expected and consistent with historical stone cultures and/or past sequencing reports of human urine . Expected bacteria included Pseudomonas, Gardnerella, Lactobacillus and Enterobactericeae, a large family that includes E. coli . Other bacteria were unexpectedly detected, particularly Brucella . Despite our best efforts, we were unable to successfully complete targeted sequencing of this organism and thus cannot confirm its identity. However, we speculate that it was actually Ochrobactrum, a close relative of Brucella that is often indistinguishable from Brucella by 16S sequencing . Intriguingly, Ochrobactrum has been identified in the urine .
From each individual, the bacteria detected by sequencing were often similar in the stone and urine samples, but the relative proportions differed. For example, in one individual, both Enterbactericeae and Gardnerella were identified in the stone and bladder urine. However, this was not always true, as Enterobactericeae dominated another individuals stone while Gardnerella dominated their urine .
How Is Hematuria Treated
If your hematuria is caused by an infection, like a urinary tract infection , hematuria is treated with antibiotics. Your healthcare provider will test your urine after treating you with antibiotics to make sure that your infection has cleared. The goal of your healthcare provider is to find the cause of blood in your urine. If no serious condition is causing hematuria, no treatment is needed.

What Do My Kidneys Do
Every day, your kidneys filter about 30 gallons of blood to remove about half a gallon of extra water and waste products. This waste and extra water make up your urine . The waste comes from the food you eat and the use of your muscles. Your urine travels to your bladder through the ureters, tubes that connect your kidney to your bladder. Your bladder stores the urine until you are ready to urinate . When you urinate, urine leaves your body through your urethra.
Your kidneys also do many other jobs, such as help:
- Make red blood cells
When your kidneys dont work the way they should, they allow waste and water to flow back into your blood stream instead of sending them out with your urine. This causes waste and water to build up in your body, which can cause problems with your heart, lungs, blood, and bones.
