BLOOD VESSELS PATHOLOGY
B LOOD V ESSELS : T HE V ASCULAR S YSTEM Taking blood from the heart to the tissues and back Arteries Arterioles Capillaries Venules Veins
The Vascular System
Differences Between Blood Vessel Types Walls of arteries are the thickest Lumens of veins are larger than arteries Skeletal muscle “milks” blood in veins toward the heart
6 C APILLARIES Only a single layer of endothelium and a basement membrane Connect arterioles and Venules Functional part of system True capillaries begin at a precapillary sphincter which controls blood flow through the capillary
L YMPHATIC S YSTEM Lymphatic capillary Lymphatic duct Lymphatic vessels All organs have lymphatic vessels except ?
