How does Carbon dioxide leave the cell and enter into the blood. Is it by diffusion? or something else? I just need to know how it goes from the cells/tissues into the bloodstream/capillaries?

most of it by simple diffusion. Mostly b/c CO2 is not present in blood as CO2 rather converted to bicarbs. Thus creating a concentration gradient need for diffusion to take place.

by-product of cell metabolism is CO2 so when arterial blood with high oxygen content enters capillary diffusion takes place. oxygen goes into the cell and CO2 out of the cell to the blood

You're right, it's diffusion.
