What is the urinary system?
Urinary System Anatomy and Function. The body takes what it needs from food and changes it into energy. After this, waste products are left behind in the bowel and in the blood. The urinary system keeps everything in balance by removing waste, like urea, extra salt, extra water and other things the body does not need..
What are the functions of the kidneys?
Their function is to: Remove waste from the blood in the form of urine. Keep substances stable in the blood. Make erythropoietin, a hormone which helps make red blood cells. Make vitamin D active.
What is the name of the tube that drains urine?
Each nephron is made up of a ball of small blood capillaries, called a glomerulus. There is also a small tube called a renal tubule, which drains the urine and joins other tubules carrying the urine out of the kidney to the ureter.
Which muscle is responsible for letting urine out of the bladder?
Urethra . The tube that allows urine to pass outside the body. The brain signals the bladder muscles to tighten, which squeezes urine out of the bladder. At the same time, the brain signals the sphincter muscles to relax to let urine exit the bladder through the urethra.
What is the name of the substance that forms urine?
Urea, together with water and other wastes, forms the urine.
Where is the bladder located?
Bladder. The bladder is a triangle-shaped, hollow organ located in the lower abdomen. It is held in place by ligaments attached to the pelvic bones. The bladder's walls relax and expand to store urine, and contract and flatten to empty urine through the urethra.
What is the function of the urinary system?
The purpose of the renal / urinary system is to eliminate wastes from the body, regulate blood volume and pressure, control levels of electrolytes and metabolites, and regulate blood pH.
What are the organs of the renal system?
Organs of the Renal / Urinary System 1 Kidneys: The kidneys are a pair of bean-shaped organs which filter blood and produce urine.. They remove wastes, control the body’s fluid balance, and keep the right levels of electrolytes . Kidneys are the most complex and critical part of the urinary system. 2 Ureter: Urine passes from the renal tube through tubes called ureters and into the bladder. 3 Bladder: The bladder is flexible and is used as storage until the urine is allowed to pass through the urethra and out of the body. 4 Urethra: Duct that transmits urine from the bladder to the exterior of the body during urination. The female and male urinary system are very similar, differing only in the length of the urethra.
What are the three regions of the kidney?
The kidney has three regions: Outer renal cortex, Inner renal medulla and Renal pelvis. Figure 3. The internal structure of the kidney is shown. (credit: modification of work by NCI) Renal Cortex: In a dissected kidney, it is easy to identify the cortex; it appears lighter in color compared to the rest of the kidney.
How many renal pyramids are there in the kidney?
There are, on average, eight renal pyramids in each kidney. Renal Pelvis: The renal pelvis leads to the ureter on the outside of the kidney. On the inside of the kidney, the renal pelvis branches out into two or three extensions called the major calyces, which further branch into the minor calyces.
What is the difference between the left kidney and the right kidney?
The left kidney is located at about the T12 to L3 vertebrae, whereas the right is lower due to slight displacement by the liver. Upper portions of the kidneys are somewhat protected by the eleventh and twelfth ribs.
Where does blood go in the kidney?
Blood flows to the kidneys through the right and left renal arteries. The renal arteries originate from the abdominal aorta and enter the renal hila to supply the kidneys. Inside each kidney these branch into smaller arterioles and penetrate deep into the renal medulla and renal cortex. Blood coming into the kidney is rich in oxygen and nutrients and waste materials. Eventually, the smaller arterioles divide and become renal capillaries where blood gets filtered, and metabolic wastes are removed to form urine. Renal capillaries are located in and around the nephrons. These renal capillaries fuse and form renal veins and leave the kidney. Blood leaving the kidney via renal veins will have less waste materials as most of the wastes materials are filtered out of the blood in renal capillaries. They also have less oxygen and nutrients as these materials are used up by the kidney cells.
What system maintains water balance?
Maintains water balance: adjusts blood volume and blood pressure. The renal system alters water retention and thirst to slowly change blood volume and keep blood pressure in a normal range. (Blood pressure homeostasis)
What organs are responsible for the flow of urine to the bladder?
Ureters: Once urine forms in the kidneys, it flows through small tubes (ureters) to the bladder. The ureters are typically between 8 and 10 inches in length. Muscles surrounding the ureters expand and contract to help urine flow to the bladder. Bladder: The bladder is a muscular organ that functions like a balloon.
What are the health problems of the urinary system?
Various health problems can arise in the urinary system. The most common conditions include: 1 Benign prostatic hyperplasia (BPH) or enlarged prostate: This occurs only in men and is a result of aging. The prostate is a walnut-sized gland that is located by the neck of the bladder, surrounding the urethra. As the prostate enlarges, it places pressure on the urethra. Such compression can cause the urethra to narrow and, in some cases, close completely. If this takes place, a patient may find it very difficult to urinate. 2 Kidney stones: Kidney stones are a common urological condition in both men and women. Kidney stones form when minerals and other solid substances accumulate in the kidneys or along any part of the urinary tract. When they're too large, these stones can block the flow of urine from the body. 3 Urinary tract infections (UTIs): Urinary tract infections also occur in both men and women. UTIs can be present in any part of the urinary system, from the kidney (pyelonephritis) to the bladder (cystitis) to the urethra (urethritis).
What tests are used to determine the root cause of a urine problem?
If these have abnormal results, additional exams may be necessary to determine the root cause of the problem. Tests used for evaluating the urine system are generally referred to as urodynamic exams and can include uroflow tests, postvoid residual volume, cystometry, electromyography, and voiding pressure studies.
How long does urine stay in the bladder?
As the amount of urine in the bladder increases, the bladder will expand. The average bladder can hold up to 2 cups of urine for two to five hours.
Where do UTIs occur?
Urinary tract infections (UTIs): Urinary tract infections also occur in both men and women. UTIs can be present in any part of the urinary system, from the kidney (pyelonephritis) to the bladder (cystitis) to the urethra (urethritis).
Where does the urethra go when the bladder is full?
In men, the urethra travels through the penis and in women, the urethra ascends above the vaginal opening. When the bladder becomes full, nerves will send signals to the brain indicating that it is time to eliminate urine from the body.
Where does urine go when it is eliminated?
Elimination: Elimination occurs when urine moves from the bladder to the urethra and then out of the body.
What are the functions of the urinary system?
Besides excretion, controlling quantity of blood and blood pressure, regulating the amount of metabolites and electrolytes in the body, and stabilizing blood pH are also some of the functions of this system.
What are the functions of the kidneys?
1. Kidney. This pair of organs, placed under the rib cage, works as a filtration system to remove waste from the blood and form urine.
How does urine travel from the kidneys to the bladder?
The ureters are the thin passageways through which urine travels from kidneys to the bladder. The ureter walls are made of muscles that constantly contract and expand to push down the urine formed in the kidneys. A few millilitres of urine are passed through the ureters every 15 seconds.
How much urine is produced in the human body?
The amount of urine produced in the human body can vary from 800 to 2000 millilitres depending on the condition of the kidneys and the quantity of liquids consumed. Read on to find out more about the function of urinary system and the diseases that can affect it.
How often does urine pass through the ureters?
A few millilitres of urine are passed through the ureters every 15 seconds. Its blockage can result in a urinary infection, affecting the function of urinary system. 3. Bladder. This works as a reservoir to store urine. It is held in the lower abdomen, by ligaments that connect it to organs and bones in the vicinity.
What causes pain in the bladder when urinating?
This occurs in the prostate gland; hence this disease is limited to the male urinary system. Advanced age can cause the gland to swell, leading to pressure on the bladder and pain while urinating. Other symptoms are an increase in frequency of urination and pelvic pain. 5.
What organs contract when you pee?
Urethra. This tube starts from the bladder and allows urine to escape the body. When the bladder’s walls contract, the sphincter muscles relax and urine is pushed through the urethra.
What is the function of the urinary system?
The main urinary system function is to filter the blood of excess water, salts, and waste products, temporarily store these within a reservoir, and intermittently expel these products from the body.
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 molecules in the filtrate. Any excess or undesired products travel ...
What muscle is involved in the expulsion of urine from the body?
The image below shows the stages of micturition and the muscles involved, namely the detrusor muscle of the urinary bladder, the internal urethral sphincter, and the pelvic floor muscle which surrounds the external sphincter.
What muscle is used to prevent urine from leaking out?
These only relax during micturition and otherwise prevent urine from constantly leaking out. The internal sphincter is an involuntary muscle; the external sphincter is voluntary. The urinary bladder is lined by a thick mucosa which forms folds when the bladder is empty but opens out as the bladder fills and expands.
What is the triangular shaped bladder?
The triangular shaped bladder is a large muscle into the top of which the two ureters empty the urine. Under the bladder, close to where it connects to a single urethra, lie two circular sphincters – internal and external. These only relax during micturition and otherwise prevent urine from constantly leaking out. The internal sphincter is an involuntary muscle; the external sphincter is voluntary. The urinary bladder is lined by a thick mucosa which forms folds when the bladder is empty but opens out as the bladder fills and expands.
How long is the ureter tube?
Ureters are two narrow but relatively long tubes (approximately 25 – 30 cm) which leave the kidneys and enter the urinary bladder.
Why do ureters get blocked?
Because the hollow areas are narrow, ureters can become blocked by debris such as salt crystals which have stuck together to create urinary stones. Complete blockage in one tube causes high pressures and urine buildup in its attached kidney and requires emergency surgery before permanent damage is done.
What system produces and stores urine?
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.
What is the name of the tube that carries urine to the kidneys?
Urine travels from the kidneys through two thin tubes called ureters and fills the bladder. What is included in the renal system? Renal system, in humans, organ system that includes the kidneys, where urine is produced, and the ureters , bladder, and urethra for the passage, storage, and voiding of urine.
What organs regulate extracellular fluid volume?
Regulation of extracellular fluid volume. The kidneys work to ensure an adequate quantity of plasma to keep blood flowing to vital organs.
