Blood has an important role in the body. As blood passes by cells, it deposits oxygen rich nutrients and carries away the cells waste.
Blood brings food and oxygen to your cells.

Capillaries change color as they pass by body cells as the blood they contain loses oxygen. Oxygen-rich blood has a brighter color than oxygen-poor blood.
Blood is the only fluid connective tissue in our body. It passes through every single blood capillary, tissue, and organ in our body. Hemoglobin in our red blood cells carry oxygen which is essential to the function of all the organ systems in our body.
Oxygen is the gas that passes from the bloodstream to body cells through the process of oxygenation. Oxygen is essential for cellular respiration, which is the process that cells use to generate energy.
The body has a double circulation the blood passes through the heart twice in one complete circuit.

Blood cells do not require oxygen because they lack mitochondria. The transportation of oxygen in the blood is accomplished by red blood cells carrying oxygen molecules bound to hemoglobin and diffusing into surrounding tissues where it is needed.
