Detailed explanation-1: -Oxygen diffuses through the cell membrane and is transported in blood plasma by free diffusion and by convection.
Detailed explanation-2: -When we breathe in, the millions of air sacs in the lungs fill with fresh oxygenated air. The oxygen then moves into the blood by passing first through the very thin walls of the air sacs and then into the capillaries, which are tiny blood vessels in a network within the lungs.
Detailed explanation-3: -In our body, 97% of the total oxygen is transported via the red blood cells and the rest 3% is transported by being dissolved in the plasma. Hemoglobin binds with oxygen and transports it to various cells of the body. After binding with oxygen, the hemoglobin forms a compound called oxyhemoglobin.
