What Organ System Does The Kidney Belong To What Organ System Does The Liver Belong To
Kidneys belong to Excretory system.Liver belongs to Alimentary system.
Explanation:
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.
How Does Blood Flow Through My Kidneys
Blood flows into your kidney through the renalartery. This large blood vessel branches into smaller and smaller blood vessels until the blood reaches the nephrons. In the nephron, your blood is filtered by the tiny blood vessels of the glomeruli and then flows out of your kidney through the renal vein.
Your blood circulates through your kidneys many times a day. In a single day, your kidneys filter about 150 quarts of blood. Most of the water and other substances that filter through your glomeruli are returned to your blood by the tubules. Only 1 to 2 quarts become urine.
The Mouth Cavity Pharynx Esophagus And Stomach
- The Mouth.
- Ingestion starts with the mouth. Teeth cut and grind food into smaller particles. Tongue and teeth MASTICATE food breaking it down into smallerparticles. The tongue is composed of SKELETAL muscle covered by mucous membrane, and helps when swallowing. The TASTE BUDS are located in the mucous membrane, when stimulated by food a nervous signalis sent which causes the salivary and gastric glands to secrete saliva. Saliva helps lubricate and moisten food, but also contains ENZYMES that begin to digest food while it is still in the mouth.
- The pharynx
- is a mucusulomembranus sack like structure which acts as a passageway for chewed food, and as an airway during respiration.
- The oesophagus
- is a long narrow mucusulomembranus tube, about 10 inches long. It is very flexible and stretches from the pharynx to the stomach. It propels food down to the stomach by awavelike movement of the esophagus muscles.
- Sphincters
- are bands of ring like muscle that act as gateways to natural openings or ‘orifices’ at various locations in the body. The muscles close the opening by contracting, and open it byrelaxing. The cardiac sphincter is at the base of the oesophagus near the heart, it relaxes to allow food to enter the stomach.
- The Stomach
- is a muscular, curved pouch like structure. It churns food and mixes it with various lubricating and digestive secretions. Food enters from the esophagus via the cardiacsphincter and is sent to the small intestine via the PYLORIC Sphincter.

The Tubule Returns Needed Substances To Your Blood And Removes Wastes
A blood vessel runs alongside the tubule. As the filtered fluid moves along the tubule, the blood vessel reabsorbs almost all of the water, along with minerals and nutrients your body needs. The tubule helps remove excess acid from the blood. The remaining fluid and wastes in the tubule become urine.

The Small Intestine Liver Gallbladder And Pancreas
- The duodenum
- is the first section of the small intestine. It is about 10 inches long. BILE from the Gallbladder and PANCREATIC secretions from the pancreas enter into theduodenum to digest food.
- The jejunum
- is the second section of the small intestine, further enzymes are secreted here, which aid digestion.
- The ileum
- is the longest section of the small intestine, where the bulk of food absorption takes place. Absorption of nutrients etc. through the mucus membrane via capillaries enter theblood stream for circulation.
- The liver
- is the largest gland in the body weighing about 3 lbs. It is a gland in the sense that it secretes BILE. It is also essential in the Metabolism of proteins, fats andcarbohydrates.
- The gallbladder
- stores bile secreted by the liver until needed in the ileum.
- The pancreas
- is a long narrow, lobed gland that is located behind the stomach. The pancreas secretes substances that aid digestion , and two hormones insulin and glucagenwhich play an important role in the ENDOCRINE system.
Once food is absorbed in the ileum, the residue is passed into the large intestine. This is between five and six feet long ! and divided into three sections:

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 .
How Can I Keep My Urinary System Healthy
You cant prevent most urinary tract problems. But you can try to keep your urinary system healthy with proper hygiene and a healthy lifestyle. To help your urinary system work the way it should, you can:
- Drink plenty of water: Staying hydrated will flush out your system and can help you prevent kidney stones and UTIs. You can try drinking cranberry juice to ward off a UTI. Compounds in cranberries may stop bacteria from growing.
- Eat a healthy diet: Low sodium, high-calcium foods may prevent kidney stones.
- Wipe the right way: Women should always wipe front to back after using the toilet. Proper wiping reduces the risk of bacteria getting into the vagina and causing a UTI.
- Empty your bladder after sex: If youre a woman, you should use the bathroom after having sex. Peeing promptly can clear out bacteria and reduce your risk of a UTI.
- Practice safe sex: Protect yourself from an STI with a condom. But be careful with spermicides because they can cause bacteria to flourish.
- Do pelvic floor exercises: Also called Kegel exercises, these can reduce your risk of urinary incontinence by strengthening the muscles in your pelvic floor.

What Else Do Kidneys Do
Kidneys are always busy. Besides filtering the blood and balancing fluids every second during the day, the kidneys constantly react to hormones that the brain sends them. Kidneys even make some of their own hormones. For example, the kidneys produce a hormone that tells the body to make red blood cells.
Now you know what the kidneys do and how important they are. Maybe next Valentine’s Day, instead of the same old heart, you can give your parents a special card featuring the kidneys!
What Do Kidneys Do
One of the main jobs of the kidneys is to filter the waste out of the blood. How does the waste get in your blood? Well, your blood delivers nutrients to your body. Chemical reactions in the cells of your body break down the nutrients. Some of the waste is the result of these chemical reactions. Some is just stuff your body doesn’t need because it already has enough. The waste has to go somewhere this is where the kidneys come in.
First, blood is carried into the kidneys by the renal artery . The average person has 1 to 1½ gallons of blood circulating through his or her body. The kidneys filter that blood about 40 times a day! More than 1 million tiny filters inside the kidneys remove the waste. These filters, called nephrons , are so small you can see them only with a high-powered microscope.

Kidney And Urinary System Parts And Their Functions
-
Two kidneys. This pair of purplish-brown organs is located below the ribs toward the middle of the back. Their function is to:
-
Remove waste products and drugs from the body
-
Balance the body’s fluids
-
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. 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.
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. 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. When all the signals occur in the correct order, normal urination occurs.
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.

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.
Secretion Of Active Compounds
The kidneys release a number of important compounds, including:
- Erythropoietin: This controls erythropoiesis, or the production of red blood cells. The liver also produces erythropoietin, but the kidneys are its main producers in adults.
- Renin: This helps manage the expansion of arteries and the volume of blood plasma, lymph, and interstitial fluid. Lymph is a fluid that contains white blood cells, which support immune activity, and interstitial fluid is the main component of extracellular fluid.
- Calcitriol: This is the hormonally active metabolite of vitamin D. It increases both the amount of calcium that the intestines can absorb and the reabsorption of phosphate in the kidney.

How Do My Kidneys Work
Each of your kidneys is made up of about a million filtering units called nephrons. Each nephron includes a filter, called the glomerulus, and a tubule. The nephrons work through a two-step process: the glomerulus filters your blood, and the tubule returns needed substances to your blood and removes wastes.

Components Of The Urinary System
The urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys form the urine and account for the other functions attributed to the urinary system. The ureters carry the urine away from kidneys to the urinary bladder, which is a temporary reservoir for the urine. The urethra is a tubular structure that carries the urine from the urinary bladder to the outside.

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.”

Functions Of The Gastrointestinal And Urinary Systems
The Alimentary Canal is a continuous tube from mouth to anus, sometimes known as the DIGESTIVE TRACT. There are three main sections:
- The mouth cavity, pharynx, oesophagus and stomach
- The Small Intestine
- The Large Intestine
Food is taken in at the mouth, chewed and swallowed. It travels whilst being digested through the pharynx and then down the oesophagus into the stomach. where further digestion occurs. It thentravels into the small intestine where it is digested and absorbed, and finally into the large intestine where water is absorbed and waste is excreted through the anus.
