The most common vascular diseases involve veins?
False, Arteries
A gradual Narrowing/Obstruction of a Lumen is called _______
Athersclerosis
A Rapid Narrowing/Obstruction of a Lumen is called a _____
Thromboembolism
Vessel walls can weaken in which two ways?
Dilation (Aneurysm) or Rupture (Dissection)
What is the term for Hardening of the arteries? Is it specific?
Arteriosclerosis, No it is non specific
What is the term for the dilation of a vascular wall
Aneurysm
What is the term for passage of blood through layers of wall
Dissection
What is the term for a blood clot in a vessel
Thrombus
A varicosity is the dilation of an artery?
False, A Vein
What is the open interior of a vessel called?
A Lumen
What cells line a vessel
Endothelial Cells
The smooth muscles in vessels are voluntarily controlled but non striated
False, they are involuntary
What are the layers of a Vessel from innermost to outermost?
Intima (Endothelia cells - Internal Elastic Lamina)
Media (smooth muscles - External Elastic Lamina)
Adventitia (CT, Nerves, Vessels)
The Intima and the Inner portion of the Media gets its blood supply via diffusion of blood from the lumen?
True
The Outer Media and Adventitia get its blood supply by diffusion of blood from the lumen
False, from vasa vasorum
The Following in the Correct Vascular Pathway
1) Large Elastic Arteries
2) Medium Sized Muscular Arteries
3) Small Arteries
4) Arterioles
5) Capillary Beds
6) Collecting Venules
7) Post Capillary Venules
8) Progressively Larger Veins
False #6 and #7 are switched Correct: 1) Large Elastic Arteries 2) Medium Sized Muscular Arteries 3) Small Arteries 4) Arterioles 5) Capillary Beds 6) Post Capillary Venules 7) Collecting Venules 8) Progressively Larger Veins
Which Structure in the vascular pathway provides vascular resistance (Blood Pressure Control)
Arterioles
Which structure in the vascular pathway is where edema and leukocyte emigration associated with inflammation begins
Postcapillary Venules
Because Veins have thinner walls they are prone to dilation/compression and penetration of tumors or the inflammatory process
True
Lymph Vessels are thin walled and lined by endothelium. They Drain lymph from intracellular fluid and eventually return it to the body via the thoracic duct.
False, from the interstitial fluid
Vascular Anomalies are very symptomatic
False, Rarely Symptomatic
Rupture of a Berry Aneurysm leads to an Epidural Hemorrhage
False a SUBDURAL hemorrhage
What Congenital Anomalie is a connection of arterial and venous systems that bypass capillaries?
Arteriovenous (AV) Fistula
What congenital Anomalie is a local thickening of medium/large artery walls that can lead to ischemia
Fibromuscular Dysplasia
