A study of the vessels, the structures and organs/areas they feed or drain.

Blood Vessels Overview

Artery Structure

The walls of arteries are generally very thick. In fact, artery walls consist of three cell layers
Innermost layer- smooth; made up of epithelial cells; Middle layer- muscle tissue; Outer wall- flexible connective tissue

Arteriole Structure

intimal layer with coils of smooth muscle fiber

Capillary

microscopic blood vessel that connects arteries and veins; has walls one cell thick, through which nutrients and oxygen diffuse into body cells, and waste materials and carbon dioxide diffuse out of body cells

Vein Structure

veins also have three layers: a thin outer layer, a middle layer and a smooth inner layer; veins are less muscular than arteries and have less elasticity

Artery Endothelium

Tunica Interna, can not contract, squamus tissue that lines the walls of the heart, blood vessels, and lymphatic vessels, simple squamous epithelia in body which reflects its location. Provides a slick, friction - reducing lining inthe cardiovascular system

Internal Elastic Larmina

A discrete layer only in medium-sized areries, assists in maintaing blood oressure

Artery Smooth Muscle

Tunica Media,in the artery these vasoconstrict (smaller vessel diameter) or vasodilate (increase vessel diameter) to specifically direct additional blood flow to certain locations as needed

External Elastic Lamina

A layer of elastic CT lying immediately outside the smooth muscle of the tunica media of an artery, separates the tunica media and the tunica adventitis (externa) in larger arteries

Artery Fibrous Tussue

Fibrous tissue contiguos with the fascisl layer in which the artery is located

Vain endothelium

Tunica Interna, can not contract, squamus tissue that lines the walls of the blood vessels, simple squamous epithelia in body which reflects its location. Provides a slick, friction - reducing lining in the veins

Vein Smooth Muscle

Tunica Media,in the vains these vasoconstrict (decrease vessel diameter) or vasodilate (increase vessel diameter) to specifically direct additional blood flow to certain locations as needed

Vain Fibrous Tussue

Fibrous tissue contiguos with the fascisl layer in which the Vain is located

Vas and Nervus Vasorum
