Answer 1

Answer:

Blood, fluid that transports oxygen and nutrients to the cells and carries away carbon dioxide and other waste products. Technically, blood is a transport liquid pumped by the heart (or an equivalent structure) to all parts of the body, after which it is returned to the heart to repeat the process.

Answer 2

$\huge\mathfrak\orange{ANSWER}$

Blood is the vital flood that transfers oxygen to other vital body parts. With the loss of blood, the body doesn't get essential oxygen resulting in death. In such a case arises the need for voluntary blood donation from somebody else, whether known or unknown to the individual.
