This is a general response.
Platelets, which are sort of sickle shaped, get caught on the edges of the tear in the tissue.
The Platelet itself is broken open to release special proteins that act as a beginning lattice work to bridge the tear. These proteins are also very "sticky," and passing red and white cells stick to them. When enough cells in the blood stream have stuck to the beginning lattice to cover up the hole so that no more blood cells can get out, the wound will stop bleeding
This does not mean that the wound won't continue to "ooze". The clear-yellowish fluid coming out is lymphatic fluid and will still be able to flow through the make-shift emergency dam. Lymph fluid itself is mostly that, fluid, but it also is another source of white blood cells. When you feel sick, you might notice that your lymph nodes feel swollen. That is actually a good sign. It means your immune system is in over-drive and is pumping out more lymphatic filled with white blood cells to attack whatever is wrong with you. Anyway, back to lymphatic fluid and wounds. Lymphatic fluid is also slightly sticky, so if you apply an outside source (e.g, a band aid), the lymphatic fluid will stick to the bandage to also help stop the flow of blood cells.
I hope I answered at least part of that question.
