Blood leaving the kidney?
827724
Each kidney receives its blood supply from the renal artery, two of which branch from the abdominal aorta. Upon entering the hilum of the kidney, the renal artery divides into smaller interlobar arteries situated between the renal papillae. At the outer medulla, the interlobar arteries branch into arcuate arteries, which course along the border between the renal medulla and cortex, giving off still smaller branches, the cortical radial arteries (sometimes called interlobular arteries). Branching off these cortical arteries are the afferent arterioles supplying the glomerular capillaries, which drain into efferent arterioles. Efferent arterioles divide into peritubular capillaries that provide an extensive blood supply to the cortex. Blood from these capillaries collects in renal venules and leaves the kidney via the renal vein. Efferent arterioles of glomeruli closest to the medulla (those that belong to juxtamedullary nephrons) send branches into the medulla, forming the vasa recta. Blood supply is intimately linked to blood pressure.\n\n\n[edit] Nephron\n \n1. Renal pyramid\n2. Efferent artery\n3. Renal artery\n4. Renal vein\n5. Renal hilum\n6. Renal pelvis\n7. Ureter\n8.

Renal columnMain article: Nephron\nThe basic functional unit of the kidney is the nephron, of which there are more than a million within the cortex and medulla of each normal adult human kidney. Nephrons regulate water and soluble matter (especially electrolytes) in the body by first filtering the blood under pressure, and then reabsorbing some necessary fluid and molecules back into the blood while secreting other, unneeded molecules. Reabsorption and secretion are accomplished with both cotransport and countertransport mechanisms established in the nephrons and associated collecting ducts.\n\n\n[edit] Collecting duct system\nMain article: Collecting duct system\nThe fluid flows from the nephron into the collecting duct system. This segment of the nephron is crucial to the process of water conservation by the organism. In the presence of antidiuretic hormone (ADH; also called vasopressin), these ducts become permeable to water and facilitate its reabsorption, thus concentrating the urine and reducing its volume. Conversely, when the organism must eliminate excess water, such as after excess fluid drinking, the production of ADH is decreased and the collecting tubule becomes less permeable to water, rendering urine dilute and abundant. Failure of the organism to decrease ADH production appropriately may lead to water retention and dangerous dilution of body fluids, which in turn may cause severe neurological damage. Failure to produce ADH (or inability of the collecting ducts to respond to it) may cause excessive urination, called diabetes insipidus.\n\nAfter being processed along the collecting tubules and ducts, the fluid, now called urine, is drained into the bladder via the ureter, to be finally excluded from the organism\n\nBlood Pressure\n\nSodium ions are controlled in a homeostatic process involving aldosterone which increases sodium ion absorption in the distal convoluted tubules.\n\nWhen blood pressure becomes low, a proteolytic enzyme called Renin is secreted by cells of the juxtaglomerular apparatus (part of the distal convoluted tubule) which are sensitive to pressure. Renin acts on a blood protein, angiotensinogen, converting it to angiotensin I (10 amino acids). Angiotensin I is then converted by the Angiotensin converting enzyme (ACE) in the lung capillaries to Angiotensin II (8 amino acids), which stimulates the secretion of Aldosterone by the adrenal cortex, which then affects the kidney tubules.\n\nAldosterone stimulates an increase in the reabsorption of sodium ions from the kidney tubules which causes an increase in the volume of water that is reabsorbed from the

This can be VERY serious. You need too see a Doctor Preferable a Neurologist or Urologist. From the link below.\n\nHematuria is the presence of blood, specifically red blood cells, in the urine. Whether the blood is visible only under a microscope or visible to the naked eye, hematuria is a sign that something is causing bleeding in the genitourinary tract: the kidneys, the tubes that carry urine from the kidneys to the bladder (ureters), the prostate gland (in men), the bladder, or the tube that carries urine from the bladder out of the body (urethra). \n\nBleeding may happen once or it may be recurrent. It can indicate different problems in men and women. Causes of this condition range from non-life threatening (e.g., urinary tract infection) to serious (e.g., cancer, kidney disease). Therefore, a physician should be consulted as soon as possible.

somethng to do with the tubules of your kidneys, but not sure what else

Absolutely, positively, YES!!!  I had a jagged kidney stone lodge sideways in the tube leading from my kidney to my bladder.  One morning I turned the water in the toilet bright red.  I remember saying to myself, "Uh, oh."  I'm sure that some other internal injury could cause your piss to turn red as well.  In any case, red urine wouldn't be "cool."

All of the liquids in the body go into the bloodstream. While there, they flow through the kidneys. These filter out all of the things that shouldn't be in the blood, and the wastes go through the ureters into the bladder. The bladder collects it until it is more than half full. Then it sends a signal to the brain that tells you you need to go to the bathroom where the pee comes out through the urethra.

yes, as a person in the health field, ANY amount of blood in your urine, should spark you into seeking medical attention...  blood in your urine could mean a problem in ur urethra, urinary bladder, ureter, or your kidney, usually an infection, but you want to go make sure and rule out all other possible causes...  b/c it hurts when u urinate, it's probably an infection, and you'll be given a course of antibiotics, but a visit to the doctor is mandatory for you at this point, before anything has a chance to progress...

You probably have a kidney infection.  You should see a doctor.  Also try drinking more water and cranberry juice (not cranberry juice cocktail, but real 100% cranberry juice) to flush out your system.

Is the blood coming out of the same place as the urine?  Could be a nasty bladder infection, or a kidney infection.  Get to the dr. girlie.

Blood has lots of functions.  It carries oxygen and nutrients.  It causes clotting.  It is the avenue which the kidneys use to remove waste from our bodies.

Its like gas for a car. Blood is a oxygen carrier, and supports all the body organs. If anyone loses too much of it- too bad!

do u mean liver cirrhosis? if the liver is damaged it doesnt work properly so substances that are usually removed by the liver pass into the blood stream....the kidney then has to filter these extra substances and can get damaged by excesses, much of which comes out in the urine.  also in severe liver failure the kidneys will become affected and in turn they will fail too

It could be a kidney problem and they are NOTHING to play around with. Get yourself to a doctor ASAP. You don't want to wind up on dialysis and needing a kidney transplant.

What is kidney failure? \n\nThe function of the kidneys is, among other things, to get rid of the waste products that result from the body's metabolism. \n\nOne of the major by-products of the metabolism of protein (muscle) is urea. The kidneys remove the waste products by extracting them from the blood and sending them along the ureter to the bladder, from where they are excreted in the urine.\n\nIf the kidney function fails, the waste products accumulate in the blood and the body. The term for this build-up is azotaemia. \n\n \nTerm watch\n\nAzotaemia is the build up of waste products that accumulate in the blood and the body when the kidneys fail to function. \n \n \nVery mild levels of azotaemia may give little or no symptoms, but if the kidney failure continues then symptoms will start to appear. \n\nIf the kidney (or renal) failure is of sufficient degree to cause symptoms, it is called uraemia.\n\nWhat causes renal failure? \n\nRenal failure can happen rapidly - over days, weeks or months (acute renal failure) or slowly over a period of years (chronic renal failure).\n\n\nAcute renal failure\n\nThis may occur with any serious illness or operation, particularly those complicated by severe infection. If the blood supply to the kidneys is reduced considerably from blood loss, a fall in blood pressure, severe dehydration or lack of salt, then the kidneys may be damaged. If this problem lasts long enough there can be permanent damage to the kidney tissue.\n\nSudden blockage to the drainage of urine from the kidney can cause damage. A kidney stone is a possible cause of this. \n\nAcute kidney damage can occur as a rare side effect of some medications and other rare conditions. \n\n\nChronic renal failure\n\nThere are many causes of chronic renal failure, including inflammatory conditions affecting the kidney tissue, as a complication of long-standing diabetes mellitus (sugar diabetes), chronic blockage to the drainage of the kidneys and as a result of certain inherited conditions such as polycystic kidney disease. Often, the cause has occurred many years earlier and cannot be identified.\n\n\nWhat are the symptoms?\n\n\nAcute renal failure\n\nHere the symptoms are largely those of the condition causing the kidney failure, such as:\n\n\nblood loss, causing a drop in blood pressure.\n\n\nvomiting and diarrhoea, causing dehydration.\n\n\ncrush injuries. If large amounts of muscle are damaged there is a release of toxic protein substances that are harmful to the kidneys.\n\n\nSudden blockage of urine drainage.\n\n\n\n\nChronic renal failure\n\nThe damage to the kidneys is usually 'silent' and not noticed at an early stage. It may be discovered incidentally from blood or urine tests done for other reasons. High blood pressure very commonly occurs with it. Symptoms are uncommon unless kidney failure is far advanced, when any of the following may be present:\n\n\ntiredness\n\n\nitching\n\n\nloss of appetite\n\n\nnausea and vomiting\n\n\nbreathlessness \n\n\nfluid retention, shown as ankle swelling (oedema)\n\n\nweakness.\n\n\n\n\nHow is renal failure treated? \n\n\nAcute renal failure \n\nMost causes of acute renal failure can be treated and the kidney function will return to normal with time. Replacement of the kidney function by dialysis (artificial kidney) may be necessary until kidney function has returned.\n\n\nChronic renal failure\n\nChronic kidney damage is usually not reversible and if extensive, the kidneys may eventually fail completely. Dialysis or kidney transplantation will then become necessary.\n\nChronic kidney failure is a serious condition which needs urgent attention when it is diagnosed, but the kidney damage is usually 'silent' and not noticed at an early stage.\n\nOccasionally it may be possible to identify and treat the cause of the renal failure itself. More commonly the treatment has to be non-specific. In all cases, careful blood pressure control is extremely important in slowing the pr

It's not perfect because, quite simply nothing can replace your kidneys. Nature is better at detoxifying your blood than any man made contrivance.  With due deference to your illness and proper care it will have a minimal effect on your life expectancy. Jules, Australia.

it cleans out your kidney
179094
The main job of your kidkeys is to clean certain waste products from your blood. They do this by carefully filtering your blood, and what they filter out becomes your urine. This means that when you pee, you are removing the waste products produced throughout your body which your kidneys expertly removed from your blood.  \n\nThis kidey's job is very important. If your kidneys stop working, these waste products can build up in your blood and over the course of a week or so will reach levels that can kill you. Fortunately, dialysis is a way to keep that from happening.\n\nDialysis is basically a way to have a machine play to the role of your kidneys and filter your blood for you. There are two main types of dialysis-- peritoneal dialysis and hemodialysis. In peritoneal dialysis, a tube is placed in your abdomen and your abdominal cavity is filled and flushed several times a day with a special fluid. In hemodialysis, needles are placed in your arm and your blood flows through a special machine. In either case, what is happening is that certain waste products are being removed from you blood, just like your kidneys would normally do. Both of the methods work, and your doctor can help you decide which is best for you.\n\nUnfortunately, people who begin dialysis often will require dialysis for the rest of their lives. Sometimes people can receive a kidney transplant. If you get a new kidney, you can stop dialysis since your new kidney can begin filtering your blood for you.\n\nStarting dialysis can be scary. It often means that a person's kidney disease has become worse. Still, people on dialysis lead full and productive lives. Even some famous actors and professional athletes have been on dialysis. Although it can seem scary at first, dialysis is a way to help people with serious kidney disease live a long and rich life.\n\nThe best person to talk to is your doctor. Your doctor can help you understand the details specific to you, and can explain more about what you can expect from dialysis.\n\nHope this helps!
