Question

Name the tissue around blood vessels​

Answer 1

Answer:

The largest blood vessels are arteries and veins, which have a thick, tough wall of connective tissue and and many layers of smooth muscle cells (Figure 22-22). The wall is lined by an exceedingly thin single sheet of endothelial cells, the endothelium, separated from the surrounding outer layers by a basal lamina.

Answer 2

Answer:

Endothelial cells

Explanation:

Endothelial cells form a single cell layer that lines all blood vessels and regulates exchanges between the bloodstream and the surrounding tissues. Signals from endothelial cells organize the growth and development of connective tissue cells that form the surrounding layers of the blood-vessel wall.
