Q

How does blood clot?

A

The injury to vessel lining triggers the release of clotting factors, then vasoconstriction limits blood flow and platelets form a sticky plug, then fibrin strands adhere to the plug to form an insoluble clot.

SA ( sinoatrial) NODE sends out an electrical stimulus , muscles of the atria contract, Av node transmits an electrical impulse, then muscles of the ventricles contract,

92
Q

What’s the order in which events listed above occur during antibody meditate immunity?

A

T Cells bind to the B cell antibody-antigen complex activating the B cell, B cell enlarges and divides to produce memory B cells and plasma cells, Plasma cells produce large quantities of antibodies, Memory ab cells remain in the blood ready to trigger another response
