Where does cellular waste get removed?
Answer (3)
There are several systems in the body that get rid of cellular waste.
The urinary system removes urea from the body.
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 the kidneys (urea).
Some cellular waste is transported by the blood to the lungs where it is released through exhalation. (ie carbon dioxide)
Some cellular waste is removed from the body through perspiration.
Cellular waste is removed from the body by various excretory organs, with the kidneys playing a critical role. Cellular wastes are transported by the blood to the kidneys, where they are filtered out of the blood and form urine .
In addition to this, the liver takes part in the detoxification process, breaking down amino acids and creating urea, which is also transported to the kidneys for excretion. Carbon dioxide, a byproduct of cellular respiration, is carried by the blood to the lungs to be exhaled.
There are also other mechanisms for waste removal in different organisms. For example, microorganisms use endocytosis and exocytosis for the intake and expulsion of substances, respectively. Flatworms have a network of tubules with flame cells that help expel waste, while annelids use nephridia and arthropods use Malpighian tubules for similar functions.
Cellular waste is removed by various systems in the body, including the lungs (exhaling carbon dioxide), kidneys (filtering urea to form urine), and skin (sweating waste). These systems work together to eliminate harmful byproducts of metabolism. The digestive system also aids in waste removal by expelling undigested materials.
