Hello dear friend ,
The answer to your question is :
Diffusion basically means the movement of particles from higher concentration to lower conentration.
In case of oxygen, concentration of our body is low than the external environment so oxygen from outside environment diffuse and mixes into blood & through blood capillaries combine with haemoglobin & form oxy- haemoglobin. The opposite thing occurs for carbon-dioxide. The concentration of carbon-dioxide is more inside the body , so it diffuses out of the body.!
Hope this helps!! thankyou & goodluck!!
