Why is blood needed by all parts of body?
Because blood act as carriers and work constantly to supply oxygen and nutrients to all the parts of the body. They also carry carbon dioxide and other waste materials to the lungs, kidneys, and digestive system to be removed from the body. Their constant supply and circulation is extremely essential for the functioning of the human body.

Thanks! But I want more answers
Humans can’t live without blood. Without blood, the body’s organs couldn’t get the oxygen and nutrients they need to survive, we couldn’t keep warm or cool off, fight infections, or get rid of our own waste products. Without enough blood, we’d weaken and die.
Here are the basics about the life-sustaining fluid called blood.
Blood brings oxygen and nutrients to all the parts of the body so they can keep working. Blood carries carbon dioxide and other waste materials to the lungs, kidneys, and digestive system to be removed from the body. Blood also fights infections, and carries hormones around the body.
Blood is the only fluid connective tissue of blood-containing living organisms that helps to connect different parts and organs of the body.
Hope it helps…
Have a great day 
That is really so interesting.
Robotics technology is being used for various tasks, including palletizing, depalletizing, and order picking. Collaborative robots (cobots) can work alongside human workers to improve productivity and safety.
