Q

Lines the vascular intima

Involved in clotting process by PRODUCING and STORING clotting component

A

Endothelial Cells or Endothelium

31
Q

Majority is produced by fibroblast

Internal Elastic Lamina is composed of:

A

Elastin and Collagen

34
Q

Sub Endothelial Connective Tissue

A

Veins (Collagen&Fibroblast) / Artery (Collagen, Fibroblast and Smooth Muscle Cells) — because artery is thicker than veins

A

Platelet

43
Q

Also known as “Giant Bernie”

A

Bernard-Soulier Syndrome (BSS)

44
Q
