The waste products of metabolism are removed from your blood. Urea and creatinine is too toxic for your brain. They are removed from your blood by your kidneys. The extra water and sodium as well as potassium and other salts are removed by your kidneys. The drug metabolites are also removed by your kidneys. The urine becomes acidic or alkaline to preserve the pH of your body.
The kidneys remove toxic substances from the blood. The main substance that the kidneys filtrate from the blood is known as urea.
The substances removed from the body by the excretory system are carried to the kidneys by the circulatory system, specifically through the blood vessels. Blood flows through the kidneys where waste products and excess substances are filtered out and eventually excreted as urine.
Plasma proteins and red blood cells are not excreted in urine because they remain in the blood when it is filtered through the kidneys and into the ureters. They are too big to be filtered. Most other substances present in blood are also present in urine since the kidneys filter out poisonous substances as well as substances that are present in excess such as salt and water.
waste materials that have toremoved by kidneys.
The waste in your blood is removed by the kidneys. The kidneys filter your blood all day every day
The kidneys purify blood through filtration. Blood enters the kidneys, where waste products and excess substances are removed through a complex system of filtration units called nephrons. The purified blood continues its circulation in the body, while the waste material is excreted as urine.
Kidneys do not form plasma proteins. All plasma proteins, or blood proteins, are made in the liver, the one exception to this being gamma globulins.
The Kidneys, where the blood/urea thing takes place.
Antidiuretic hormone (ADH) is removed from the blood by being broken down and cleared by the kidneys. It is filtered out of the blood by the kidneys and then excreted in the urine.
substances that are excreted from the kidneys are urea, uric acid, creatinine, toxins, drugs, plasma inorganic ions,(Na+,K+,Ca2+..ect.) H+, HCO3-, of course H2O, and anything else the body doesn't need that's found in the blood plasma. substances that are reabsorbed are amino acids, proteins, glucose, water, plasma inorganic ions and anything the body needs that is found in the blood plasma. the nephrons are nonselective and secrete everything in the plasma, and the capillaries then reabsorb the vitamins minerals nutrients ect. that the body needs back into the blood, everything the body doesnt need goes to the bladder. What will cause the kidneys to lose more water from the blood? Diuretic hormones

In plasmapheresis, antibody-laden blood plasma (the liquid portion of the blood) is removed from the body. Red blood cells are separated and put back into the body with antibody-free plasma or intravenous fluid.
