|
ARTERIES
|
Carry oxygenated blood away from the heart. (Think A for Arteries = Away) Exception - pulmonary ateries cary deoxygenated blood.
|
|
|
CAPILLARIES
|
Responsible for exchange between blood and tissue cells --> release of O2 --> to become veins
|
|
|
VEINS
|
Contian valves to produce a one way direction of blood. (Think V for Veins = Valves) Carry deoxygenated blood to the heart from the body and the heart. Exception - pulmonary veins carry oxygenated blood back to heart.
|
|
|
PHLEBITIS
|
Vein inflammation
|
|
|
THROMBOPHLEBITIS
|
Inflammation of a vein with/due to clot formation.
|
|
|
Varicose veins
|
Leaky insuffient valves (back up) in carrying blood towards the heart. Veins and venules carry most of the blood in the system.
|
|
|
Arteritis
|
Artery inflammation
|
|
|
Aneurysm
|
Dilation and/or dissection of the blood vessel wall with concommitent weakness (ie. aortic or brain)
|
|
|
ORTHOSTATIC / POSTURAL HYPOTENSION
|
A drop/extreme lowering of blood pressure as person becomes upright. Associated with disease.
|
|
|
Blood Flow
|
Amount of blood that passes through a vessel in a given time. (Liters/min) It is determined and effected by 1. Pressure and 2. Resistance
|
|
|
Resistance
|
Blood flow is effected by 1) viscosity 2)blood vessel length 3)blood vessel radius
|
|
|
BP
|
Blood Pressure is effected by 1) CO2 2) blood volume 3) peripheral resistance Vasomotor Center located in the medulla. That controls blood vessel diameter --> changes in blood pressure.
|
|
|
ANP
|
Atrial Natriuretic Peptide receptor cells located in the heart's atrium detect elevated blood pressure --> vasodilation --> decrease in salt & water --> decrease in BP
|
