What are the two primary functions of the urinary system?
Your urinary system, also called the renal system or urinary tract, removes waste from your blood in the form of urine. It also helps regulate your blood volume and pressure, and controls the level of chemicals and salts (electrolytes) in your body's cells and blood.
What is the most important thing about the urinary system?
1) The most important organ of the urinary system are the kidneys, bean-shaped structures that are located under the ribs in the middle of the back. Their function is to remove urea from the blood and get the urine into the bladder. 2) The ureters are thin tubes that serve as a link between the kidneys and the bladder.
Which of the following is a function of the urinary system quizlet?
What are the functions of the Urinary System? The main function is to eliminate waste from the body. The kidney, ureters, urinary bladder, and the urethra all work to clean up the waste made by the cells in the body.
What is not a primary function of the urinary system?
The urinary system does not regulate the production of insulin and glucagon. The urinary system regulates fluid, electrolytes, and acid-base balance. It also regulates red blood cell formation through secretion of erythropoietin. The urinary system also removes waste products from the blood.
What are four functions of the urinary system?
The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH.
Which is the main organ of urinary system?
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 a fact about the urinary system?
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 primary function of the bladder quizlet?
To reabsorb the water lost during filtration. To prevent constant urination and dehydratation.
What are the main functions of the urinary system 3.4 1?
What are the main functions of the Urinary System? Remove urine from the body and other nitrogenous wastes. Beginning with the kidney, trace the organs through which urine travels. Nervous system- Tells you when you're thirsty.
What are the primary functions of the kidney quizlet?
The primary function of the kidneys is to filter blood to produce urine. Where is urine stored? Urine is stored in the bladder.
What are the two main parts of the nephron?
A nephron is made of two parts: a renal corpuscle, which is the initial filtering component, and. a renal tubule that processes and carries away the filtered fluid.
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.
Which muscle is responsible for holding urine in the bladder?
Sphincter muscles: These muscles surround the opening of the bladder, which extends to the urethra. The sphincter muscles expand and contract to hold urine in the bladder and to release urine when needed. Urethra: The urethra is the tube that connects the bladder to the genitals in order for urine to pass outside of the body.
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.
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).
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.
What is the function of the urinary system?
Your urinary system filters your blood to get rid of what your body doesn’t need. It eliminates extra water and salt, toxins, and other waste products. Different parts of the urinary system perform tasks including: Filtering blood. Separating the toxins you don’t need from the nutrients you do need. Storing and carrying urine out of your body .
How does the urinary system work?
Here’s how the urinary system works: Your blood enters each kidney through lots of little arteries. Your kidneys filter your blood, separating toxins from nutrients. Vitamins, minerals, nutrients and proteins return to your bloodstream. Waste products and urine move through your ureters to your bladder.
Why does my urine leak?
Urination problems: Loss of bladder control, or urinary incontinence ( leakage), causes urine to leak a little or a lot. Urinary incontinence most often occurs in women, usually after pregnancy or later in life. It can be worse when you cough, laugh, sneeze or jump. Overactive bladder happens when you feel the sudden urge to urinate often. Medications can help treat these conditions.
How common is UTI in women?
UTIs are more common in women than in men. More than 60% of women will get a UTI in their lifetime. About half of women over 65 experience urinary incontinence, usually because of stretched muscles from pregnancy and childbirth. Kidney stones are also fairly common, occurring in about 1 in every 10 people.
What causes urinary problems?
Some common urinary disorders are: Infections: Urinary tract infections and sexually transmitted infections (STIs) can cause issues in the kidneys, urethra, or bladder. These infections occur when bacteria or viruses enter the urinary tract through the urethra.
Why is it hard to pee?
In men, an enlarged prostate (also called benign prostatic hyperplasia or BPH) can block the ureter so it’s harder to urinate. BPH can be treated with medications or surgery. Other causes of ureteral obstruction include pregnancy and gastrointestinal (GI) issues like Crohn’s disease.
What is the urinary system?
The urinary system includes the kidneys, ureters, bladder and urethra. This system filters your blood, removing waste and excess water. This waste becomes urine. The most common urinary issues are bladder infections and urinary tract infections (UTIs).
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.
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.
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 name of the substance that forms urine?

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.
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.
What is the function of the kidneys and urinary system?
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.
What muscles help keep urine from leaking?
Two sphincter muscles. These circular muscles help keep urine from leaking by closing tightly like a rubber band around the opening of the bladder. Nerves in the bladder. The nerves alert a person when it is time to urinate, or empty the bladder. Urethra.
How many ureters are there in the body?
Two ureters. These narrow tubes carry urine from the kidneys to the bladder. Muscles in the ureter walls continually tighten and relax forcing urine downward, away from the kidneys. If urine backs up, or is allowed to stand still, a kidney infection can develop. About every 10 to 15 seconds, small amounts of urine are emptied into the bladder from the ureters.
What tube allows urine to pass outside the body?
Urethra. This tube 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.
How do kidneys remove urea from the blood?
Release hormones to regulate blood pressure. Control production of red blood cells. The kidneys remove urea from the blood through tiny filtering units called nephrons.
What does it mean when your urine is yellow?
