(B) Under normal physiological conditions,arterial blood contains approximately $19 	ext{ ml}$ of $O_2$ per $100 	ext{ ml}$ of blood. Venous blood returning from the tissues contains approximately $14 	ext{ ml}$ of $O_2$ per $100 	ext{ ml}$ of blood. This indicates that $5 	ext{ ml}$ of $O_2$ is delivered to the tissues for every $100 	ext{ ml}$ of blood. The percentage of oxygen released by haemoglobin is calculated as: $(5 	ext{ ml} / 19 	ext{ ml}) 	imes 100 \approx 26.3 \%$. Therefore,the closest standard value accepted in biological contexts for this exchange is $25 \%$.

During one circulation of blood from lungs to the tissues and back through the circulatory system,the percentage of haemoglobin giving up its oxygen to the tissues is (in $\%$)
