Blood clotting
•
It’s a defence mechanism
Blood clotting prevents this dangerous loss of blood occurring in addition to blocking pathogens
invading the cut and infecting the body
...
So damaged blood vessels leads to protein fibres trapping red blood cells to
form a clot through numerous events
...
Have a sac of cytoplasm rich in vesicles (enzymes)
...
Surrounded by cell surface membrane
...
Collecting platelets release clotting factor- thromboplastin (protein)- released by damaged tissues at
site
...
Converts
fibrinogen into fibrin (site of cut)
...
As the sequence of steps involved is clotting is complex – this is an essential fail safe
mechanism (generates risk of danger/fatal blockage)
