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.

Capillaries take oxygen and nutrients from the blood to the cells in the body. They also remove waste products, such as carbon dioxide, from the cells.
Capillaries - they are the smallest vessels that serve as arteries and veins.
Red blood cells do not "move files." Instead, they circulate throughout the body to transport oxygen from the lungs to tissues and remove carbon dioxide for excretion. This process occurs in the bloodstream as the cells travel through the arteries, capillaries, and veins.
Nerve cells receive blood and oxygen through a network of small blood vessels called capillaries. These capillaries are located close to nerve cells in order to deliver nutrients and oxygen for their metabolic needs. The brain, for example, has a dense network of capillaries to ensure a constant supply of blood and oxygen to nerve cells.
Capillaries are very thin blood vessels. Oxygen and nutrients and hormones can pass through the walls of the capillaries and reach the body's cells, while red blood cells remain in the capillaries.
Capillaries. Red cells that group together normally tend to do so in rouleaux; those that stay as individuals will have greater opportunities to absorb oxygen. If they pass through capillaries individually will be more efficient as transporters of oxygen.
Oxygen and nutrients are passed to cells through the bloodstream. Oxygen is transported by red blood cells, while nutrients are carried in the plasma. Blood vessels deliver these substances to cells throughout the body, where they are taken up for cellular respiration and processes necessary for function and growth.
The capillaries exchange oxygen, nutrients, and waste in cells. They accomplish this via diffusion.
