NEWLY UPDATED ANPH 1002 UNIT 0NE THE
CARDIOVASCULAR SYSTEM WITH BEST
SOLUTIONS
What is the eighth clotting factor? - answer-
Antihemolytic factor A, comes from the platelets and
endothelial cells, follows the intrinsic pathway.
What is the ninth clotting factor? - answer-Antihemolytic
factor B, comes from the liver and follows the intrinsic
pathway (needs potassium)
What is Homeostasis? - answer-The process by which the
body seals a ruptured blood vessel and prevents blood
loss.
What are the three steps to complete homeostasis? -
answer-1 vascular spasm, 2 Formation of the platelet
plug, 3 coagulation
,What is a vascular spasm? - answer-Smooth muscles in
the vessels that contract dramatically in response to a
damaged vessel
What are the circular layer in a vascular spasm? - answer-
They constrict the flow of blood
What triggers the circular layer to contract? - answer-
Endothelins that are released by vessel lining cells and
pain-receptors
What are the longitudinal layers of the vascular spasm? -
answer-They draw the vessel back into the tissue
What is the formation of the platelet plugs? - answer-
Platelets that clump together and bind to the exposed
collagen and endothelial lining
What is the formation of the platelet plug assisted by? -
answer-The Von Willebrand factor
,What is the Von Willebrand factor? - answer-They help
stabilize the growing platelet plug
What do platelets release? - answer-ADP, serotonin and
prostaglandins that contribute to homeostasis.
What is coagulation? - answer-The formation of a blood
clot
What is a blood clot made of? - answer-fibrin
What is the purpose of ADP in homeostasis? - answer-
Helps additional platelets adhere to the injured sit,
reinforcing the plug.
What is the purpose of serotonin in homeostasis? -
answer-Maintains vasoconstriction
What is the purpose of prostaglandins and phospholipids
in homeostasis? - answer-Activates further clotting
chemicals and maintains vasoconstriction
, What happens if any steps in homeostasis fails? - answer-
A hemorrhage results
What is a hemorrhage? - answer-Excessive bleeding
What is the purpose of clotting factors in coagulation? -
answer-They prompt reactions that activate more
coagulation factors
What are the three pathways in coagulation? - answer-
The extrinsic, intrinsic and common pathways
What triggers the Extrinsic pathway? - answer-trauma
What triggers the intrinsic pathway? - answer-Internal
damage
What is the common pathway? - answer-merged
extrinsic and intrinsic pathways
