Question

When we got cut blood solidify after sometime but herodinaria when leech suck blood didt gets solidify?

Answer 1

when we get a cut blood solidifies after sometime due to presence of fibrinogen in the plasma and also due to the presence of platellets these two proteins helps in the clotting of blood so that the blood from our body doesn't leave out as a RBC as a lifespan of 120 days and thus we will not be able to live if all the blood come out a and we will not be able to survive as the food will not get transport it and all the cell will stop doing respiration especially the brain cells

hirudinaria and latest have enzyme present in their saliva which deactivates fibrinogen and platelets to act so they prevent clotting of blood by inserting The Saliva inside our body
