1. How does bleeding from a wound be stopped? A wound stops bleeding due to the process of clot formation called coagulation. Coagulation is from the Latin coagulatus meaning "to cause to curdle". All this chemical action creates a plug called a blood clot. After a time‚ moisture is squeezed out of the clot and it contracts. This process is called syneresis. It’s not widely known but the same chemical process of syneresis also happens in the formation of jams and jellies. 2. How does the immune

found that the conductivity of protoplasm remained independent of changes in viscosity and by Gelfan and Quigley (7) to the blood coagulation process since their experiments showed that during the coagulation process there is no change in the conductivity of shed whole blood or plasma‚ in spite of the almost infinite increase in viscosity during coagulation. In view of the concentration of excess electrolytes in the gelatin experiments of Arrhenius‚ as well as in protoplasm and in blood
