Why do we need blood in our body?​

Answer 1

Explanation:

Blood is needed to keep us alive. It 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

Answer 2

Answer:

Blood is composed of the following living cells which support and maintain our body tissues: Red blood cells, which are filled with hemoglobin and carry oxygen from our lungs to the rest of our bodies. White blood cells, which defend against infection. Platelets, which help blood to clot when injuries occur.
