Answer 2

Structure of Arteries and Veins

Arteries and veins are composed of three main layers in their walls. The innermost layer of these vessels is formed by:

1. Endothelium (One-layered epithelium) The innermost layer of arteries and veins is composed of endothelium, which is a type of one-layered epithelium that lines the interior surface of blood vessels. This layer serves various functions, including regulating the passage of substances and maintaining the vessel's integrity.

2. Connective Tissue The middle layer of arteries and veins consists of connective tissue, which provides structural support and flexibility to the vessels.

3. Smooth Muscle Tissue The outermost layer of arteries and veins is made up of smooth muscle tissue, which allows the vessels to contract and relax, thereby regulating blood flow and pressure.

These three layers work together to facilitate the proper functioning of arteries and veins, enabling them to carry blood throughout the body and maintain circulatory health.
