Study Notes
- Platelets are formed in the bone marrow and are responsible for blood clotting.
- When there is a cut or nosebleed, fibrinogen (a plasma protein) creates long fibers that form a mesh over the opening.
- Platelets block this mesh, creating a clot.
- Exposure of the clot to air results in a scab.
- This clotting process is the body's defense against blood loss and a barrier preventing germs from entering.
