Anatomy of Blood Vessels
These vessels carry blood away from the heart under high pressure.
What is arteries?
Systolic blood pressure less than 100 mmHg.
What is hypotension?
complete endothelium with tight junction.
What is continuous capillaries?
Valves in the veins fail and walls expand.
What is varicose veins?
Inadequate flow of blood through system causing cell death in tissues.
What is circulatory shock?
These vessels return blood to the heart under low pressure.
What is veins?
Drop in blood pressure upon rising or standing
incomplete endothelium that slows blood flow.
What is sinusoid capillaries?
Late stage atherosclerosis.
What is arteriosclerosis
blood born allergy leading to widespread vasodilation and fluid loss to tissues.
what is anaphylactic shock?
Site of material exchange between blood and tissues.
What is capillaries?
Respiratory pumps and muscular pumps assist with this type of return.
What is venous return?
porous endothelium that is very permeable.
What is fenestrated capillaries?
Abnormal accumulation of fluid in tissues.
What is Edema?
low venous return due to venous vasodilation.
What is neurogenic shock?
Alternate circulation around blocked artery or vein via another pathway.
What is collateral flow?
the passage of fluid through to an organ or tissue, usually referring to the delivery of blood to a capillary bed in a tissue.
What is perfusion?
Movement across capillary walls due to osmosis
What is water gradients?
Vessel walls abnormally thick, narrowed and less compliant.
What is atherosclerosis?
Low cardiac output due to heart damage.
What is cardiogenic shock?
Force against the vessel walls
What is blood pressure?
100 extra points -> where is BP usually taken?
Blood pressure, peripheral resistance and velocity of blood flow all have this kind of relationship.
Basically, they all increase and decrease together.
Movement across capillary walls due to diffusion.
what is solute gradients?
Localized dilation or outpouching of a blood vessel.
What is aneurysm?
Infection causing widespread vasodilation and fluid loss to tissues
What is septic shock?
