ARTERIES
Arteries are blood vessels that carry blood away from the heart. All arteries, with the exception of the pulmonary and umbilical arteries, carry oxygenated blood. Aorta is the largest artery. ARises from heart.
CAPILLARIES
Capillaries are the smallest of a body's blood vessels and are part of the microcirculation. They are only 1 cell thick. These microvessels, measuring 5-10 μm in diameter, connect arterioles and venules, and enable the exchange of water, oxygen, carbon dioxide, and many other nutrient and waste chemical substances between blood and surrounding tissues.
VEINS
In the circulatory system, veins are blood vessels that carry blood toward the heart. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood. They differ from arteries in structure and function; for example, arteries are more muscular than veins and they carry blood away from the heart.

Nicotine is the blood vessels' constrictor. Not all blood vessels, of course, but mainly the peripheral blood vessels, including the brain capillary blood vessels.

Red blood cells are too small to contain blood vessels. They are cells and they travel in blood vessels.
Blood vessels do not carry air. Blood vessels carry blood, and this blood can carry dissolved gas molecules.
Blood vessels. Constriction of blood vessels increases blood pressure by reducing the space for blood flow, while dilation of blood vessels decreases blood pressure by increasing the space for blood flow.
The smallest blood vessels are the capillaries.
Blood vessels can form new blood vessels, this is called angiogenesis.
