Capillaries. Since they are only once endothelial cell thick, they can exchange gas, nutrients, and waste across their membrane. Capillaries in the brain have endothelial cells close together to onyl allow a slecetive exchange of materials, while capillaries in the kidney or liver have gaps between the endothelial cells to allow the exchange of a lot of materials.
In the blood vessels and in the lymph vessels.
Vasodilation is the widening of blood vessels resulting from relaxation of the muscular wall of the vessels. Usually occurs during exercise, so that more oxygenated blood can be pumped to the body's tissues.

blood vessels
The heart itself helps ensure blood only flows one way. The arteries are the vessels that the heart pumps blood into, while the veins then get blood pulled from them by the heart.

Capillaries!
The main fuction of blood vessels is to help the blood reach the arteries
Capillary: A tiny blood vessel where substances are exchanged between the blood and the body cells.
The human circulatory system consists of arteries, veins, and capillaries. The capillaries are the thin-walled vessels that connect arteries and veins and allow for the exchange of materials between blood and tissue fluid.
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
Oxygen exchange takes place in the capillaries, which are the smallest blood vessels in the body.
Capillaries are known as exchange vessels. Capillaries are the smallest of vessels and allow nutrients and waste to pass through blood and body.
Capillaries are the smallest blood vessels in the body and are thin enough to allow for the exchange of materials (such as nutrients, oxygen, and waste products) between blood and surrounding tissues. Their thin walls facilitate this exchange by allowing substances to pass through easily.
Those tiny and beautiful blood vessels are called as capillaries. You have millions of them in your body. The nutrition and oxygen is given out, at the proximal end. The metabolic wastes and carbon bi oxide in taken in, at the distal end.
Blood capillaries
Capillaries are the semipermeable vessels that allow for the exchange of materials, such as oxygen, nutrients, and waste products, between the blood and the surrounding tissues.
Materials are exchanged between cells and the blood mainly at the capillaries. Capillaries are tiny blood vessels with thin walls that allow for the exchange of gases, nutrients, and waste products between the blood and surrounding tissues. This exchange process occurs through the process of diffusion.
