Question

Why does jaundice cause yellowing of skin, eyes, nails etc.?​ ​

Answer 1

• The $RB{C}^{\prime }s$ have $120$ days of lifespan. Once they die, the $RBCs$ are taken away be $WBCs$ by means of phagocytosis. During this process, the iron-containing pigment haemoglobin gets converted into bilirubin which is a yellow-coloured pigment. This goes into bile secreted by liver and passed out through faeces or urine. ​
• When excess of $RBCs$ are damaged resulting in the excess production of bili­rubin, it causes disfunctioning of liver. The excess production of this pigment imparts yellow colour to skin, eyes, nails, etc.​
