Kidneys belong to Excretory system.Liver belongs to Alimentary system.


Kidneys are part of the excretory system . This system is associated with excretion of metabolic waste products and formation and excretion of urine. Other organs of the system are ureters, urinary bladder and urethra.

The diagram of excretory system :

Liver is a part of the alimentary system . This system has two main parts : Digestive tract and digestive glands. From mouth to anus all organs form a tract, which is called digestive tract.Salivary glands, Liver and pancreas are part of digestive glands.

As the name suggests the digestive system is associated with digestion, absorption and metabolism of nutrients. Liver forms bile, which is essential for fat digestion and absorption. And liver is the organ of metabolism. So it belongs to alimentary system.

Sometimes Liver, gall bladder and bile ducts are included into a system called the Hepatobiliary system.

What Are The Parts Of The Urinary System

The kidneys, ureters, bladder and urethra make up the urinary system. They all work together to filter, store and remove liquid waste from your body. Heres what each organ does:

  • Kidneys: These organs work constantly. They filter your blood and make urine, which your body eliminates. You have two kidneys, one on either side of the back of your abdomen, just below your rib cage. Each kidney is about as big as your fist.
  • Ureters: These two thin tubes inside your pelvis carry urine from your kidneys to your bladder.
  • Bladder: Your bladder holds urine until youre ready to empty it . Its hollow, made of muscle, and shaped like a balloon. Your bladder expands as it fills up. Most bladders can hold up to 2 cups of urine.
  • Urethra: This tube carries urine from your bladder out of your body. It ends in an opening to the outside of your body in the penis or in front of the vagina .

Lesson Background And Concepts For Teachers

The human body has many methods for cleansing itself. Carbon dioxide is released from the body by exhaling, salt is released through sweat, and food waste as feces. The body also cleanses itself by releasing excess minerals, toxins, and unused water through the urinary system in the form of urine.

The kidney is the main organ in the urinary system. Most people have two kidneys, which are located near the lower back, and protected by the lower ribs. They are bean-shaped, and about the size of a fist. The other parts of the urinary system are the ureters, urethra, bladder, adrenal glands, renal veins and renal arteries. The kidneys play a key role in this system, acting as filters for the blood. The basic cleaning unit within the kidney is called the nephron, which is made up of capsules, tubules, and blood vessels. Each kidney has about one million nephrons!

The renal arteries bring the blood into the kidney to be cleaned . The blood is pumped through little bunches of blood vessels, or capillaries, called glomeruli. These little bunches of glomeruli are located inside nodules called Bowmans capsules. There is a small amount of space between the glomeruli and the walls of the capsules. Excess salts, minerals, and toxins pass through the walls of the capillaries in the glomerulus, then through the porous walls of the capsule and into the proximal tubule. All of this occurs inside the cortex, the outer portion of the kidney.

Description Of The Urinary System

Which System Do Kidneys Belong To

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 per day based on typical daily fluid intake of 68 ounces , National Institutes of Health . Other factors in urinary system function include fluid lost through perspiring and breathing. In addition, certain types of medications, such as diuretics that are sometimes used to treat high blood pressure, can also affect the amount of urine a person produces and eliminates. Some beverages, such as coffee and alcohol, can also cause increased urination in some people.

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 Cleveland Clinic. Each nephron consists of a ball formed of small blood capillaries, called a glomerulus, and a small tube called a renal tubule. 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 ureters are about 8 to 10 inches long , according to the Cleveland Clinic.

How Common Are These Conditions

The most common urinary issues are bladder infections and urinary tract infections . 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.

Organ Systems Working Together

Renal cortex: structure and function (preview) – Human Anatomy | Kenhub

Organ systems often work together to do complicated tasks. For example, after a large meal is eaten, several organ systems work together to help the digestive system obtain more blood to perform its functions. The digestive system enlists the aid of the cardiovascular system and the nervous system. Blood vessels of the digestive system widen to transport more blood. Nerve impulses are sent to the brain, notifying it of the increased digestive activity. The digestive system even directly stimulates the heart through nerve impulses and chemicals released into the bloodstream. The heart responds by pumping more blood. The brain responds by perceiving less hunger, more fullness, and less interest in vigorous physical activity, which preserves more blood to be used by the digestive system instead of by skeletal muscles.

Communication between organs and organ systems is vital. Communication allows the body to adjust the function of each organ according to the needs of the whole body. In the example above, the heart needs to know when the digestive organs need more blood so that it can pump more. When the heart knows that the body is resting, it can pump less. The kidneys must know when the body has too much fluid, so that they can produce more urine, and when the body is dehydrated, so that they can conserve water.

What Are The Kidneys And Urinary Tract

The urinary tract is one of the systems that our bodies use to get rid of waste products. The kidneys are the part of the urinary tract that makes urine . Urine has salts, toxins, and water that need to be filtered out of the blood. After the kidneys make urine, it leaves the body using the rest of the urinary tract as a pathway.

Kidney Pain Location And Sensation

Most people tend to associate pain in the area between the ribs and hips as either digestive problems or muscular back pain. However, kidney pain isnt always felt in the same place as the kidneys location.

Dr. Charles Patrick Davis on MedicineNet explains that renal or flank pain can be felt anywhere between the lowest rib and the buttocks. The pain may also radiate to the groin or abdominal area. Depending on the underlying cause of the kidney pain, you may feel the pain in just the left or right side of your back. However, sometimes kidney pain affects both sides of the back.3

The Ureters Urinary Bladder And Urethra

Two ureters transport urine from the kidneys into the urinary bladder. Urinary Bladder size fluctuates depending on the volume of urine stored in it. Once it reaches a certain level ofurine stretch receptors send signals to the brain to cause a conscious desire to urinate. The urethra is a small tube through which urine flows from the bladderto the exterior of the body.

What Are The Parts Of The Urinary Tract

People usually have two kidneys, but can live a normal, healthy life with just one. The kidneys are under the ribcage in the back, one on each side. Each adult kidney is about the size of a fist.

Each kidney has an outer layer called the cortex, which contains filtering units. The center part of the kidney, the medulla , has fan-shaped structures called pyramids. These drain urine into cup-shaped tubes called calyxes .

From the calyxes, pee travels out of the kidneys through the ureters to be stored in the bladder . When a person urinates, the pee exits the bladder and goes out of the body through the urethra , another tube-like structure. The male urethra ends at the tip of the penis the female urethra ends just above the vaginal opening.

How Does My Digestive System Break Food Into Small Parts My Body Can Use

liver as excretory organ | liver physiology | liver function | liver function in human body | liver

As food moves through your GI tract, your digestive organs break the food into smaller parts using:

  • motion, such as chewing, squeezing, and mixing
  • digestive juices, such as stomach acid, bile, and enzymes

Mouth. The digestive process starts in your mouth when you chew. Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food.

Esophagus. After you swallow, peristalsis pushes the food down your esophagus into your stomach.

Stomach. Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices.

Pancreas. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins. The pancreas delivers the digestive juice to the small intestine through small tubes called ducts.

Liver. Your liver makes a digestive juice called bile that helps digest fats and some vitamins. Bile ducts carry bile from your liver to your gallbladder for storage, or to the small intestine for use.

Gallbladder. Your gallbladder stores bile between meals. When you eat, your gallbladder squeezes bile through the bile ducts into your small intestine.

The Urinary Bladder Is A Reservoir For Urine

Urine flows through the ureters into the urinary bladder. In women, the bladder is located in front of the vagina and below the uterus. In men, the bladder sits in front of the rectum and above the prostate gland. The wall of the bladder contains folds called rugae, and a layer of smooth muscle called the detrusor muscle. As urine fills the bladder, the rugae smooth out to accommodate the volume. The detrusor relaxes to hold the urine, then contracts for urination. An adult bladder is full at about half a liter, or about two cups.

Engineers, especially biomedical engineers, have done a lot to help people who have problems with their kidneys. Engineers have designed a machine, called a dialysis machine, which works like an artificial kidney. This device takes a personâs blood, filters out the extra salt and wastes, and then returns the clean blood to their body. Engineers have also designed a system to help astronauts go to the bathroom in outer space.

Today we are going to learn a little bit more about how kidneys work and how engineers need to understand this before they can design helpful instruments like dialysis machines and toilets for astronauts.

Urinalysis is a test that studies the content of urine for abnormal substances such as protein or signs of infection. This test involves urinating into a special container and leaving the sample to be studied. Urodynamic tests evaluate the storage of urine in the bladder and the flow of urine from the bladder through the urethra. Your doctor may want to do a urodynamic test if you are having symptoms that suggest problems with the muscles or nerves of your lower urinary system and pelvisureters, bladder, urethra, and sphincter muscles. Urodynamic tests measure the contraction of the bladder muscle as it fills and empties. The test is done by inserting a small tube called a catheter through your urethra into your bladder to fill it either with water or a gas. Another small tube is inserted into your rectum or vagina to measure the pressure put on your bladder when you strain or cough. Other bladder tests use x-ray dye instead of water so that x-ray pictures can be taken when the bladder fills and empties to detect any abnormalities in the shape and function of the bladder. These tests take about an hour.

Diseases Of The Urinary System

Different specialists treat urinary system ailments. Nephrologists treat kidney diseases, while urologists treat problems with the urinary tract, including the kidneys, adrenal glands, ureters, bladder and urethra, according to the American Urological Association . Urologists also treat the male reproductive organs, while gynecologists often treat urinary diseases or disorders in females, including yeast infections. Nephrologists and urologists often work with endocrinologists or oncologists, depending on the disease.

Urinary tract infections occur when bacteria enter the urinary tract they can affect the urethra, bladder or even the kidneys. While UTIs are more common in women, they can occur in men. UTIs are typically treated with antibiotics, according to Dr. Oscar Aguirre, a urogynecologist in Denver. In the United States, about 8.1 million people have a urinary tract infection each year, according to the American Urological Association.

Incontinence is another common disease of the urinary system. “The most common bladder problems I see in my practice in women are frequent urges to urinate and leakage of urine,” said S. Adam Ramin, urologic surgeon and founder of Urology Cancer Specialists in Los Angeles. “The most common bladder problems in men are frequent urination at nights and incomplete bladder emptying. This is usually due to an enlarged prostate causing obstruction of bladder emptying.”
