Transcript of Excretory System

Main organs of the Excretory System The main organs of the excretory system are the
-urinary bladder
-lungs What is the Excretory System? The Excretory System The Respiratory System The Endocrine System If you drink too much water, hormones are released by the endocrine system that let more urine be produced.
There are also adrenal glands placed on the top of each kidney. The adrenals release adrenaline into your body. By Zoe D, Sarah R, Carolyn S, and Sam B
Period: 6 The Excretory System The excretory system is responsible for removing solid, liquid, and gaseous waste. It also has the job of controlling the blood volume by removing excess water and urea. The excretory system keeps the body in balance. The Liver Main Job: To filter the blood coming from the digestive tract before it passes to the rest of the body. The liver makes important proteins for blood clotting and other functions. Also, the liver detoxifies chemicals and metabolizes drugs.
The Liver is on the right side of the body. It is about three pounds and reddish-brown. The liver can normally not be felt because it is protected by the rib cage.
Jobs: To protect the human body, have sensory receptors, permit growth and movement,
and release waste products on the surface of the
The layer outside of your skin is called the epidermis. It is the only part of your skin we can see. The Skin
Main Job: During urination, the bladder muscles contract, and two sphincters open to allow urine
to flow out.
Look: Muscle sack just above the pelvis. When empty the urinary bladder is about the size and shape of a pear. Urinary Bladder
Main Job: The urethra carries urine, that was previously held in the bladder, out of the body.

Look: A small tube 1 1/2 inches long. Urethra Lungs Main Job: To remove gaseous waste from your body by removing carbon dioxide.
Location: Located under your ribs and one on each side of the thorax. Main job: The kidneys remove liquid waste called urea. This then becomes urine. Each day, your kidneys make 1.5 liters of urine.
Look: Located beside the spine in your back. They are reddish brown and shaped like beans. The Kidneys How Does the Excretory System Work With Other Systems? The Digestive System The digestive system is the system that turns food into fuel and energy for your body.
The excretory system is the system that removes waste from the body.
While the digestive system collects and removes undigested solids, the excretory system filters compounds from the blood stream and collects them in urine. The excretory system cleans the waste products that the respiratory system makes.
A waste product of the lungs in the respiratory system is carbon dioxide and the excretory system gets rid of that by exhaling it out. How Does the Excretory System Work With Other Systems? How Does the Excretory System Work
With Other Systems? Diseases that Effect the Excretory System The cause: Infections are caused by organisms that cannot be seen without a microscope. These microbes include fungi, viruses, and bacteria. Bacteria are the most common cause of UTIs.
Symptoms: Symptoms of UTIs vary by age and gender, but common symptoms are pain on the lower back, a frequent need to go to the bathroom, and a burning feeling in the bladder or urethra.
Treatment: Antibiotics are the most common treatment for a UTI. Urinary Tract Infections are infections that effect any organ in the urinary system. More Diseases that Effect the Excretory System Kidney Stones The Cause: Kidney stones are motley caused when one does not drink enough water.
Symptoms: The symptoms of kidney stones are that you experience extreme pain that will not go away, fever, chills, vomiting, urine that smells bad, and a burning feeling when you urinate
Treatment: You treat kidney stones by taking appropriate medication prescribed by the doctor, and drinking lots of water. Why the Excretory System is the Best! We believe that the excretory system is the best system! We are correct, for without the excretory system, we could not be alive. The excretory system is in charge of getting rid of waste and cleaning our blood. With out doing this job, our blood would poison the other parts of our body. If all of the parts of our body were poisoned, the other systems wouldn't be able to work. So every system relies on the excretory system. That makes it the best! Fun Facts! Citations On average, the volume of water lost daily by exhaling is a little more then the volume of a soft drink can.
The volume of water lost by your skin each day is about the volume of a 20 oz soft drink bottle
Water that normally is removed from body tissues accumulates and causes swelling of the ankles and feet
Sometimes fluids build up around the heart and it has to work harder to move blood to the lungs In Conclusion The excretory system is the best system. We know it is because your body relies on it the most. It gets rid of your bodies extra waste and keeps it alive. If it didn't do its job properly, we would all be poisoned. The main parts of the excretory system are the liver, skin, urinary bladder, ureter, urethra, kidneys, and lungs. These run together to form the excretory system and keep your body alive using the help of the digestive, respiratory, and endocrine system. This system is the most important system! -yogasiddha.blogspot.com

Main Job: Each kidney has its own ureter. They help urine move from the kidneys to the bladder.
Look: They are narrow, hollow, muscular tubes, usually about nine inches long, They connect the kidneys to the bladder.
