Answer» Answer: Blood clotting is a simple function dome for reducing the blood activity in a blood vessel. Explanation: Wjem a blood vessel gets affected EITHER by getting cut or swelling or an accidental hit blood clottong is seen. Blood clotting has 3 important STEPS:- 1). The affected blood vessel firstly narrows down. GIVING more friction for the blood flow and small opeaning for blood to continue its movement. 2). Platelets comes into picture here. Platelets segregates itself from serum and goes to the narrowed blood vessel site. These activated platelets turns from round shaped to spiny shape, so that they can attach themselves to affected blood vessel. 3). Fibrin protein gets activated now which forms a net like structure around the blood components such as RBC's. This entrapment does not allow blood to flow further. With RBC's even platelets too get trapped which produces more of clot. |
