everything flows from high concentration toward low.

The exchange of nutrients,including oxygen,and wastes with carbon dioxide occurs through simple diffusion. The gases move toward the area that is lower in that gas. While wastes and nutrients do the same.
how does the exchange of nutrients and oxygen with ways and carbon dioxide they place in the capillaries?
The capillaries exchange oxygen, nutrients, and waste in cells. They accomplish this via diffusion.
Its all diffusion.
Capillaries!
Capillary.capillariesCapillaries.Blood flow moves from arteries, to arterioles, to capillaries, to venules, to veins, to the heart, and then back to arteries. Capillaries are where the exchange of oxygen and other materials happens.Capillaries
Capillaries exchange food, oxygen, and carbon dioxide.
Capillaries are known as exchange vessels. Capillaries are the smallest of vessels and allow nutrients and waste to pass through blood and body.
Exchange takes place by diffusion .

Capillaries are tiny thin-walled blood vessels that connect the smallest arteries and veins and allow the exchange of nutrients and waste between the blood and tissues. Oxygen and carbon dioxide are exchanged between the circulatory and respiratory systems; oxygen diffuses from the lungs into the bloodstream and is transported by erythrocytes (red blood cells) throughout the body. Carbon dioxide diffuses out of the blood into the alveoli and goes the reverse direction through the respiratory system and out the nose.
