Blood Vessel Wall - an overview | ScienceDirect Topics
Blood vessels deliver oxygen and nutrients to body tissues. The major constituent of the vessel wall is the extracellular matrix (ECM), collectively known as stroma or matrix. In arteries or veins, the ECM constitutes more than half of the wall mass and contains mainly collagens and elastin.
18.2: Structure and Function of Blood Vessels
The wall of a capillary consists of the endothelial layer surrounded by a basement membrane with occasional smooth muscle fibers. Some variation in wall structure is seen depending on the size of the capillary.

2023年10月30日 · There are three distinct layers forming the walls of arteries and veins. The innermost layer is the tunica intima. This layer is lined by endothelium, which is comprised of simple squamous epithelial cells.
20.1 Structure and Function of Blood Vessels - OpenStax
Distinguish between elastic arteries, muscular arteries, and arterioles on the basis of structure, location, and function; Describe the basic structure of a capillary bed, from the supplying metarteriole to the venule into which it drains; Explain the structure and function of venous valves in the large veins of the extremities

2023年5月1日 · Structure. The structure of the vessels of the vascular system is highly specialized to suit their individual functions and anatomic relationships. These differential changes appear in three shared layers of the vessel wall. The tunica externa, or tunica adventitia, is the outermost layer of the vessel wall.
The Adventitia: Essential Regulator of Vascular Wall Structure …
The vascular adventitia acts as a biological processing center for the retrieval, integration, storage, and release of key regulators of vessel wall function. It is the most complex compartment of the vessel wall and is comprised of a variety of ...

c of the adventitial layer is the presence of small blood vessels, called the vasa vasorum. The vasa vasorum supplies blood and nourishment to the tunica adventitia and outer parts of the tunica media, as these layers are too thick to.
Artery Wall - an overview | ScienceDirect Topics
We report the clinical evidence linking arterial stiffness and organ failure and discuss the molecular pathways that are activated by the increase of mechanical stress in the wall. We also discuss the possible interventions that could limit arterial stiffening with age, such as regular aerobic exercise training, and some pharmacological approaches.

The purpose of this chapter is to provide a general overview on the structure and composition of blood vessels. Moreover, the cellular constituents of the vessel wall, as well as the different types of blood vessels, are discussed.
