Blood is taken away from the lungs as it circulates.
by diffusion
The biconcave nature of red blood cells increases their surface area and assists in better oxygen diffusion.
diffusion from red blood cells in capillaries to the tissue cells
Yes it is.

diffusion
Oxygen and nutrients reach cells within tissues via the bloodstream. Blood is also responsible for transporting waste away from the cells.

oxygen out of blood, carbon dioxide into blood
Through diffusion. There is less oxygen in the cells as opposed to the capillaries, so through simple diffusion, the oxygen goes from an area of high concentration to lower concentration.
Red blood cells drop off oxygen to tissues and cells in the body through the process of diffusion in capillaries. Oxygen molecules bind to hemoglobin in red blood cells in the lungs and are released when the red blood cells reach tissues with lower oxygen concentration.
