The red blood cells (hemoglobin) give up respiratory gasses to other cell tissue through the thin capillary walls. Like you said this happens by diffusion. The gas molecules are small and can pass through the thin cell membranes and capillary walls into the tissue, and diffusion means they move from an area of higher concentration (the hemoglobin) to an area of lower concentration (the cells which have lower concentration because they have used some of the oxygen they had).
To bring oxygen into the body, transfer gases into the tissues, and remove carbon dioxide from the body.
Both oxygen and carbon dioxide diffuse from body tissues into the blood.

The three functions of the blood when the circulatory system is working with the respiratory system are to take in needed gases from the lungs, expel waste gases from the tissues, and carry hormonal messages that communicate the body's needs to the respiratory adn circulatory systems.
