Final answer:
Unconjugated bilirubin is indeed removed from the blood by the liver, where it is converted into a water-soluble form for excretion. This statement is true.
Step-by-step explanation:
The statement that unconjugated bilirubin is removed from the blood by the liver is True. In fact, bilirubin, the main bile pigment, is a waste product of the breakdown of old or damaged red blood cells. This process begins in the spleen and the resulting bilirubin is then transferred to the liver through the splenic vein of the hepatic portal system. In the liver, bilirubin binds to albumin to form a complex that is transported to the liver where the bilirubin is taken up, leaving albumin in the plasma. Once in the liver, bilirubin is conjugated with glucuronic acid by the enzyme UDP glucuronyl transferase, converting it into bilirubin monoglucuronide and then into bilirubin diglucuronide, which is water-soluble and can be excreted into the intestines via the bile duct. Eventually, bilirubin in the intestine is transformed into stercobilin, giving feces their brown color. Some bilirubin derivatives are also excreted in the urine.
True, unconjugated bilirubin is removed from the blood by the liver.
Unconjugated bilirubin is produced when red blood cells are broken down and it is toxic. To be excreted, unconjugated bilirubin is converted into a water-soluble form in the liver. It is then conjugated with glucuronic acid to make it water soluble and easily excreted through the bile into the intestines. From there, it is converted into stercobilin and gives the characteristic brown color to feces.
