Kidney transplants are better as it can give you a better way of life and there is less chance of it failing, unlike dialysis there is not much treatment involved after the operation has happened you may have to go for checkups but with dialysis the treatment is a lot longer.

With dialysis it is computerised and you have to be on it for longer than a kidney transplant and there is more risk of it failing.

Insufficient blood flow to the kidneys can cause kidney failure. The kidneys can't filter toxins from the blood without enough blood flow. - Eimantas

Most people who are born without a kidney lead normal, healthy lives - eimantas

Kidneys are bean-shaped organs that are located against the back muscles in the upper abdominal area. They sit opposite each other on both the left and right side of the body - Eimantas

Inside the medulla are pyramids each of which contain nephrons

Renal pelvis- is a funnel for uridine flowing into the ureter. Collects urine

The regulation and removal of these substances in the blood stream is carried out by millions of tiny tubes called kidney tubules or nephrons. These work by filtering the blood via diffusion.

Cortex-part of the kidney where unfiltration occurs, filters large molecules from the blood

Medulla- the blood enters into the kidneys through the renal. Collect the filtrate to go to the bladder. Where water, salt and urea are removed from the blood

The kidneys are the excretory organs involved in controlling the amoint of water and salt and removing the urea out of the blood. Urea is toxic to our bodies.

Receptor cells in the brain detects the water concentration in the brain. The water concentration is high we have a lower ADH. The kidney tubules reabsorb less water back into the blood. The urine is going to have a high concentration of water. If the water concentration is low we have a higher ADH. The kidney tumbles reabsorb more water back into the blood. The urine is going to have a low concentration of water

Ureters - the ureters are narrow, hollow, muscular tubes that connect your kidneys to the bladder
Kezia baxter

# data[].attributes.body
When the water concentration is high the kidney tubules reabsorb less water but when water concentration levels are low the kidney tubules reabsorb more water back in the blood

Kidneys help clean blood and maintain water balance

Renal artery- carry blood from the heart to the kidney

Kidneys are important because they help filter out all the toxins that are placed into the body therefore your kidneys are extremely important to the way your body functions
