"To introduce our artificial blood, we first need to discuss the shortcomings of natural blood."
Zhang Yuyun knew Chen Yiyang was an outsider, so she patiently explained to him.
"Natural blood has a very significant drawback in the medical field, which is its difficulty in preservation.
Platelets in the blood can be preserved for a maximum of four days without clotting. Meanwhile, red blood cells can be preserved for up to twenty days under low temperatures.
This is why, once a severe accident occurs and hospitals are full of patients urgently needing blood transfusions, there's a need to call for people to donate blood.
Because of preservation issues, blood banks are constantly running low. Even when there's a large amount of blood donated at a given time, if not used promptly, it has to be destroyed due to expiration."
When Zhang Yuyun mentioned this, Chen Yiyang remembered that he had seen similar news before.
