Why must urea be removed from the body?
Urea is a Toxin create by the liver to get rid of Ammonia (also a toxin) so it needs to leave the body. It leaves via the left kidney and out of the body as urine.
Both the respiratory and urinary systems remove waste and harmful toxins from the body. When we respire, or breathe, Carbon Dioxide is removed as this is not healthy for the body. Similarly, toxins, called urea, are removed in urine. As well as the build up of waste, called urea, salt and water is also removed.
Many processes in the body produce nitrogen-containing wasted-products. This nitrogen will sometimes form ammonia, which is poisonous to the body. In order to remove this poisonous ammonia from the body, ammonia is converted to urea which is non-toxic for the body, and more easily removed. This happens in the urea cycle. Thus urea is a way of disposing leftover waste-nitrogen from our nitrogen metabolism.
Urea is made in the the liver and removed from the body via the kidneys in the urine flow as the microscopic solid by product (i.e., the insoluble waste that will not be leaving via the anus) created along with urine. It is an effective way of removing nitrogenous waste from the body in a relatively non toxic form
Both are Nitrogen based molecules, but Urea(in urine) is CO(NH2)2, whereas ammonia is NH3. Excess nitrogen in mammals is toxic, and is removed from the body either in the form of urea or ammonia. Urea is produced in the liver, extracted from the blood by the kidneys, then excreted in the urine. If your kidneys cannot handle the load of nitrogen, then the nitrogen is excreted as ammonia through your sweat.
Urea is a solid, colorless, odorless compound used as a raw material in the chemical industry, especially in fertilizer production. It is also produced in the liver in people and animals as a breakdown product of nitrogen-containing compounds (primarily amino acids, the building blocks which make up proteins). It is removed from the body in the urine, and to a small degree, in sweat. Urine is a mixture of water, electrolytes (like sodium, potassium, chloride)…
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.
* Excretion is the mane given to the removal from the body of: (substances in bold): * ** The waste products of the body's chemical reactions, the products of some reactions are poisonous and must be removed from the body: ** *** Break down of glucose during respiration produces CO2, which is carried away by the blood and removed in the lungs. *** Deamination of excess glycogen in the liver to form glycogen and urea…
There are several systems in the body that get rid of cellular waste. 1. The urinary system removes urea from the body. 2. The spleen removes aged and damaged blood cells from the blood stream and breaks them down. The liver then removes the hemaglobin and breaks it down further. Some of the by products are excreted with the bile (ie heme) and some are released back to the blood stream to be removed by…
