Answer 2

Answer:  

The ‘bluish discoloration’ of the skin is due to cyanosis.

Explanation:  

This is a ‘condition’ that occurs when there is insufficient oxygen supply to the body; the haemoglobin loses its red colour and attains a blue colour. Haemoglobin carries oxygen and gets converted to oxy haemoglobin in order to supply oxygen to different ‘parts of the body’. In the case of hypoxia the blood or the haemoglobin in the blood does not have oxygen to carry and supply to all the tissues.
