Arteries |
Always carry blood away from the heart Except for the 2 pulmonary arteries Elastic in nature Under high pressure 3 well developed lays/tunica to the wall Largest vessels
|
|
|
Name the layers of the artery wall |
Tunica externa/adventitia Tunica media tunica intima/interna |
|
|
Tunica intima |
simple squamous epithelium |
|
|
Tunica media |
smooth muscle |
|
|
Tunica Externa |
thin connective tissue with irregular elastic and collagenous fibers |
|
|
Aneurysm |
abnormal expansion of a blood vessel wall |
|
|
Atherosclerosis |
accumulation of fatty substances on the inner linings of arteries |
|
|
Capillaries |
Wall of capillary is simple squamous E.T. Under little to no pressure smallest of all vessels in size largest in number capillary beds selectively permeable walls (Blood Brain Barrier)
|
|
|
Capillaries Exchange |
Gases - Oxygen/CO2 Waste Material Nutrients |
|
|
Capillary Transfer Methods |
Osmotic pressure hydrostatic pressure/filtration simple diffusion |
|
|
Veins |
3 layers to wall (less developed then arteries) low pressure carry blood toward heart veins (except for the 4 pulmonary veins) carry Oxygen poor blood Have valves |
|
|
Veins move blood by |
Skeletal muscle hydrostatic pressure valves breathing |
|
|
Varicose veins |
abnormally swollen and enlarged veins, especially in the legs |
|
|
Phelbitis |
inflammation of the veins |
|
|
Thrombo Phelbitis |
blood clots cause by inflammation of the veins |
|
|
Movement of blood in blood vessels |
Arteries to arterioles to capillaries to veinules to veins |
