Right.

You're welcome.

Yes, you are correct! Most of our blood vessels are capillaries. Capillaries are the smallest and thinnest blood vessels in our body, responsible for the exchange of oxygen, nutrients, and waste products between the bloodstream and surrounding tissues. They connect the arterial and venous systems, and their extensive network ensures that every cell in the body is supplied with the necessary blood supply. To arrive at this answer, you likely used prior knowledge about the circulatory system or conducted a quick search about the composition of blood vessels. Well done!
