Final answer:
D) 1. Cyanosis; 2. Jaundice The skin's yellowish tone due to liver problems is called jaundice, and the bluish tint of the skin when blood oxygen is low is known as cyanosis.
Step-by-step explanation:
The yellowish tone that skin can take on due to liver malfunction is called jaundice. This condition is caused by the accumulation of bilirubin, a product of the breakdown of red blood cells, which the liver is typically responsible for eliminating. When the liver does not function properly, bilirubin levels rise, leading to the skin's yellow tint. On the other hand, when blood oxygen is low, hemoglobin in the blood is dark red, giving the skin a bluish tint, a condition known as cyanosis. Cyanosis occurs when oxygen supply is restricted, such as during an asthma attack or a heart attack, and does not involve changes in the skin's natural pigmentation.
Jaundice is the term used to describe the yellowish tint that the skin can take on due to liver malfunction. It is caused by the accumulation of bilirubin, a yellow pigment, in the body. On the other hand, when the blood oxygen is low, the skin can appear blue due to the dominant presence of dark red deoxyhemoglobin, a condition called cyanosis.
