The thin walled blood vessels are called capillaries.
Capillaries are the smallest blood vessels in the body (in terms of diameter), measuring about 20 micrometres (or one cell) across.

The smallest blood vessels in the body are capillaries, whose lumens can be as small as one blood cell thick in some areas.
The smallest blood vessels are the capillaries.
The smallest blood vessels are called capillaries.
your arteries are the biggest, then the veins (the only blood vessels with valves), then the capillaries are the smallest as they are usually only one cell thick

"capillaries"
Actually the smallest blood vessels are capillaries. These blood vessels are only about 1 cell thick and is where the gas and nutrient exchanges occur. It is also the cross-bridge between vein and arteries.
Capillaries are the smallest of all the blood vessels, they have extremely thin walls - just one cell thick. There are some spider-like cells (called pericytes) dotted along the outer wall of capillaries which help to stabilize them.
Capillaries. It is only one cell thick (adaptation for diffusion)
The granule cell of the cerebellum is the smallest cell in the human body, but the red blood cell is the smallest blood cell.
Capillaries - The endometrium (epithelial lining/wall) of the capillaries is only one cell thick optimizing diffusion/osmosis between it and the tissue cells of the body
Blood vessels can form new blood vessels, this is called angiogenesis.
