Kidneys
The kidneys serve many purposes. They regulate electrolytes, blood pressure, and acid levels. They also help to filter the blood.

How do the kidneys keep us alive?
Kidneys are necessary as they: maintain the balance between salt and water (which helps to regulate blood pressure); regulate the body's acidity (acids versus bases - pH level); filter blood by removing wastes and diverting them to the urinary bladder; and produce numerous hormones that help to manage the body in other ways (including regulating calcium in the blood, red blood cell production, and overall blood pressure).
Thus, their primary function is to keep blood healthy.

What is left kidney with mild pelvocaliectasis?
A left kidney with mild pelvocaliectasis means that the kidney has a dilated renal pelvis as well as calyces. This can be see through an ultrasound and it curable.
How can there be 2 kidneys in the human body?
People who lose a kidney due to trauma, disease or donation appear to do just fine so it seems that you truly have two in order to give you a spare. The kidneys are easily injured in traumatically (falls) and due to illnesses such as stones and infections and their function is vital to life so having two on opposite sides of the body provides a safety net.
The general design of the human body is one of bilateral symmetry; the body has a left side and a right side which are largely similar. There is only one brain, but the brain does have two hemispheres. There are two lungs, two arms, two legs, two eyes and two ears, and two kidneys. Having two of a given body part creates a backup system. So, you can lose a kidney and still survive.
What are symptoms of Dog kidney disease?
Feline leukemia virus (often abbreviated as FeLV) is a viral infection of cats that results in the development of leukemia, a cancer of white blood cells.
Symptoms of feline leukemia include losing weight without losing appetite, increased frequency of illness and longer time to clear an infection. Lymph nodes may also become enlarged.
Is kidney failure and kidney insufficiency mean the same thing?
Kidney failure is an acute stage, and can often be a secondary complication to another condition or situation, such as from a reaction to medication or from dehydration. Chronic kidney disease is a chronic illness. Acute kidney failure has a good chance of being 100% reversible if caught early. Chronic kidney disease is manageable with dialysis, but is not reversible.
Why is it possible to have only one kidney?
The body needs to purge the "impurities" it obtains by way of consumption of liquid and food. By doing this the kidneys through diffusion of certain substances, mainly salt or NaCl, diffuses things that the body does not need out of the kidneys and into the urine for expulsion from the body. Now pending any significant increase in impurities the body can suffice with only one kidney working the filtration and expulsion routine . Persons who have donated a kidney are told to withhold from substances, foods, drinks etc. that can cause the kidney to over exert itself.
Your kidneys are there to:
1. filter wastes and extra fluid from your blood
2. keep the proper balance of minerals like sodium, phosphorus, calcium, and potassium in your blood
3. help maintain a healthy blood pressure
4. make hormones that keep your blood and bones healthy, one of them is all that is really needed to do this job.
You can survive on one kidney since having only one can still do all this but there are still some small problems that come with having only one kidney. They are small and will you might not notice them till a while(years) later. The affects are:
1. High blood pressure
2. Proteinuria (Excessive protein in the urine, this can be a sign of kidney damage)
3. Reduced GFR (The glomerular filtration rate, this will affect how well your blood is cleaned.)
They will not affect your health if they are under control, so see you doctor regularly to make sure they are.

Having only one kidney is actually not uncommon. As long as the one kidney is doing the job, many people never know they only have one. My nephew in 3rd grade found out last year he only has one. MOST of the problems listed above are not actually common for people with only one kidney.
Are the kidneys part of the circulatory system?
The kidney is a part of the Urinary System. It is not part of the Circulatory System
What is the structural unit of the kidney?
Nephron is the basic structural and functional unit of the kidney.
https://en.wikipedia.org/wiki/Nephron
It is composed of a renal corpuscle and a renal tubule.
The renal corpuscle consists of a glomerulus and the Bowman's capsule. It is the nephron's initial filtering component.
The components of the renal tubule are the proximal convoluted tubule, loop of Henle and the distal convoluted tubule.
The size of normal kidneys after maturity is a length of about 12cm, breadth of about 6cm and thickness of about 3cm. When one kidney is removed, the remaining kidney enlarges to compensate for the functional absence of the first.
The kidney is located behind the abdominal cavity in the retroperitoneum.
The kidney is a major organ in the lower section of the abdomen.
The kidney preforms 2 major tasks in the body one consisting of filtering the blood and the other is to distribute nutrients from what ever liquid you may drink to the rest of the body. The fluid waste leaves the kidneys through the ureters and into the bladder.
I have lupus and about 7 other immune disorders. My filtration rate is at about 35 (non black) and my cretinine is now at 1.25 about. My renal ultra sound came back with "increased echogenicity". What does that mean? Thanks Sharon
What are the layers of the kidney?
Cortex- outer kidney region that is composed of glomeruli, Bowman's capsule and proximal/distal convoluted tubules
Medulla- inner kidney region that is composed of collecting ducts and the Loops of Henle
Pyramids-con-shaped areas of the medulla; contains the Loops of Henle and the collecting ducts
Pelvis- expanded upper end of the ureter; the kidney branches called calyces open into it
Calyx- receives urine from the collecting ducts and directs the urine into the pelvis
Capsule- connective tissue covering of the kidney
What are the Cells in the kidney?
Most humans are born with two kidneys as the functional components of what is called the renal system, which also includes two ureters, a bladder and a urethra.
What organ is above the kidneys?
From the top down till I get to the kidneys: Brain (lets hope), lungs - heart, (this is where it gets complicated because they are not all one right on top of each other but next to) liver, Gallbladder, Stomach, spleen (on your left, above your kidney), gallbladder (on your right, above your kidney), and the pancreas is kind of 'behind' (the kidneys) and on the left. wala! now we have reached our destination: the kidneys
or the easy answer
The Adrenal glands there are two they are considered organs, and they sit right on top of each kidney.
What happens if a person with kidney failure do no want to undergo kidney dialysis?
Bottom line: You need at least one funtioning kidney to live. Bite the bullet and undergo the dialysis. It's a terrible procedure to have to endure, but it can and will save your life.
How do you know when your kidney is shutting down?
Go on dialysis.
Start looking for donors.
Talk to your doc about a transplant.
There are a range of reasons why kidneys will start to "shut down". In most cases its due to a an extreme water infeection which will turn to septtisemia. Antibiotics can help. If its down to lack of fluids which are vital for the kidneys to operate correctly then increase water intake and IV fluids can help.
If the kidneys are diseased then the options above are really the next step.
What fact about the kidneys did Dr. Richard Bright discover in 1827?
Dr Richard Bright is known as the Father of Nephrology for his work with Thomas Addison and Thomas Hodgkin. During this time he discovered that protein in the urine was an indication kidney disease, which came to be known as Bright's disease.
What happen to us if you had no kidney?
with out kidneys our kidneys filter the blood of the bad particles and excrete them as urine. without kidneys the blood would be dirty and our organs would be effected
What will happen when kidneys stop functioning?
Total and permanent kidney failure is called ESRD. If a person's kidneys completely stop working your body fills with extra water and waste . It's called uremia. Hands or feet might swell and you will feel tired and weak because the body needs clean blood to function properly.
Untreated uremia may lead to seizures or coma and will ultimately result in death. A person whose kidneys stop working completely will need to undergo dialysis or kidney transplantation.
What is produced by the kidneys?
The kidney secretes the hormones renin, calcitriol and erythropoietin.
Renin - also known as angiotensinogenase, helps to control the body's blood pressure by regulating the balance of fluid and electrolytes in the body.
Calcitriol - This is a form of Vitamin D which regulates calcium and phosphorous levels in the body.
Erythropoietin - This is a glycoprotein hormone and has an important role in the production of red blood cells in the bone marrow.
What is the function of the kidney in the excretory system?
Yes, the pancreas in birds is located near the small intestine. The first function of the pancreas is to neutralize acids that are found in the mixture passed on from the stomach. If this does not occur serious damage could occur to the intestine of the bird. Another major function of the pancreas is to produce insulin so that all the bird's cells are supplied with glucose.
