Oxygen exchange takes place in the capillaries, which are the smallest blood vessels in the body.
ARTERIES ALWAYS take blood AWAY from the heart.
Blood is transported in arteries, veins, and capillaries. Arteries are the vessels that take blood from the heart. Veins are the vessels that take blood back to the heart, and capillaries are the tiny vessels that attach the arteries and veins. Transport of oxygen and nutrients occurs on the capillary level.
No, oxygen does not dilate blood vessels. In fact, oxygen has a vasoconstrictive effect, which means it causes blood vessels to constrict or narrow. This helps regulate blood flow and pressure in the body.
The blood vessels around the brain help supply energy for your brain
Blood vessels in the dermis layer of the skin supply nutrients and oxygen to skin cells. These blood vessels bring in nutrients and oxygen from the rest of the body through the bloodstream.

Blood, oxygen, and nutrients.
It is to remove carbon dioxide and take in oxygen.
The frog's skin has many small blood vessels so that oxygen can go through the thin skin, through the fine blood vessels, and into the blood stream, allowing for the frog to breathe more easily.
Nutrients and oxygen have to get to the outside of the heart. So the blood vessels on the outside have that job. The nutrients and oxygen can't get to the cardiac muscle from inside the heart. Blood vessels that lead from the heart that are high in oxygen and nutrients have their first branch off the aorta that goes to these blood vessels. That's how important these vessels are to the heart and how it functions.
Your blood vessels circulate blood, gases (E.G., oxygen), and nutrients to tissues throughout your body.
