Final answer:
Jaundice, or yellow skin, can be caused by liver disease or liver cancer, excessive hemolysis, but not decreased perfusion to vital organs or anemia.
Step-by-step explanation:
Jaundice, or yellow skin, can be caused by various factors. One of the causes is liver disease or liver cancer, which can result in the accumulation of bile and the yellow pigment bilirubin in the body. Another cause is excessive hemolysis, the destruction of red blood cells. When the capacity of the liver to excrete bilirubin is exceeded, unconjugated bilirubin accumulates in the blood and causes jaundice. Additionally, decreased perfusion to vital organs or anemia are not direct causes of jaundice.
