How does kidney remove waste?
The bean-shaped kidneys filter waste products out of the bloodstream and dispose of them by creating urine. Urine is made of these waste products dissolved in water.
What are wastes and how do the kidneys participate in their removal from the body?
The kidneys filter out the waste products and excess fluids from the body and dispose of them in the form of urine, via the bladder. The clean blood flows back to the other parts of the body. If your kidneys did not remove this waste, it would build up in the blood and cause damage to your body.
How do your kidneys keep your fluid levels balanced?
One way the the kidneys can directly control the volume of bodily fluids is by the amount of water excreted in the urine. Either the kidneys can conserve water by producing urine that is concentrated relative to plasma, or they can rid the body of excess water by producing urine that is dilute relative to plasma.
What system uses kidneys to eliminate waste?
The urinary system includes the kidneys, ureters, bladder and urethra. This system filters your blood, removing waste and excess water. This waste becomes urine.
Where does urea leave 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.
Why is it important to get rid of urea from the body?
The kidney and urinary systems help the body to get rid of liquid waste called urea. They also help 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.
What happens if there is too much urea in the body?
Uremia can lead to kidney failure when left untreated. Someone with uremia may have seizures, loss of consciousness, heart attacks, and other life-threatening symptoms. Some will need a kidney transplant. Kidney failure may also damage other organs, so untreated uremia can result in liver or heart failure.
Why does urea need to be removed from the body?

How does urea leave the liver?
The urea and water are released from the liver cells to the bloodstream and transported to the kidneys where the blood is filtered and the urea is passed out of the body in the urine. Urea is very soluble and a small molecule, so it is relatively easily passed out by the kidneys as a solution in water.
What happens if waste builds up in your body?
When nitrogen waste products, such as creatinine and urea, build up in the body, the condition is called azotemia. These waste products act as poisons when they build up. They damage tissues and reduce the ability of the organs to function.
What color is your urine when you have kidney failure?
When kidneys are failing, the increased concentration and accumulation of substances in urine lead to a darker color which may be brown, red or purple. The color change is due to abnormal protein or sugar, high levels of red and white blood cells, and high numbers of tube-shaped particles called cellular casts.
How can you tell if your kidneys are not working properly?
