1What is an Atheroma?
- AArtifical thickening of arterial cell walls that excludes a thick lipid mix
- BArtificial coarsening of arterial cell walls that shed bacteria into the bloodstram
- CBacterial biofilm forming over the cell wall
2What causes the Endothelial Dysfunction that begins atheroma growth?
- ACigarette smoke
- BExcess LDL's
- CBacterial infection
- DAutoimmune disorders
- EDiabetes
3What happens to epithelial cells during Endothelial Dysfunction?
- AThey become lipoprotein soluble and lose cell repellant quality
- BThey become lipoprotein inoluble and gain cell repellant quality
- CThey become lipoprotein soluble and gain cell repellant quality
4VCAM- A monocyte adhesion molecule that allows them to enter the vascular wall
- AVerdadero
- BFalso
5Once monocytes convert to macrophages in tissue, what do they produce?
- AROS
- BAcids
- CBases
6During Lipid Deposition, lipids can easily enter the damaged endothelial walls
- AVerdadero
- BFalso
7What happens to LDL's once they enter the tissue
- AThey're oxidied by macrophages
- BThey're reduced by macrophages
8LDLs are so easily reduced due to low tissue antioxidants
- AVerdadero
- BFalso
9What happens when Macrophages take up too many LDL's?
- AThey become dying Foam cells
- BThey become dying Plasma cells
- CThey become dying Mast cels
10As the macrophages die, the release lipid pools
- AVerdadero
- BFalso
11Name the two main components of the plaque?
- AFoam cells
- BLipid pools
- CLDLs
- DMast cells
- EPlasma cells
12Vascular cells form a fibrous cap over the developing clot
- AVerdadero
- BFalso
13What, potentially can happen to the fibrous plaque coat?
- AIt calcifies and fissures at the edges
- BIt becomes layered with t-cells and macrophages
- CBacteria stick to it and invade tissues
14Name the effect of arterial plaques
- ABlood flow decreases
- BBlood pressure rises
- CBlood flow increases
- DPlaque forces artery to widen
