Question

Why do yaks have large lungs ?​

Answer 1

$\huge\underline\orange{Answer}$

The yak has adapted to these conditions: It is considered to take in larger volumes of air than most other cattle, to retain a higher proportion of the oxygen breathed in and to be protected against harmful effects of solar radiation by the colour of its coat and skin.

Answer 2

Answer:

Because yak is well adapted to high altitude, having larger lungs and heart than cattle found at lower altitude,as well as greater capacity for transporting oxygen through their blood due to the persistent of foetal haemoglobin throughout life. So yaks have large lungs.
