Which Of The Following Is Not Involved In Hemostatsis Stoppage Of Bleeding

What is hemostatsis?

Hemostasis is the process to stop bleeding.

Which of the following are involved in the clotting process?

All of the above

On blood thinners, how can I stop bleeding when I cut myself?

At the drug store buy a styptic pencil.

Hemostatic chemicals use Chitosan in commercial products such as roll gauzes, and granular powders. Zeolite, for example is used in QuikClot, a dressing.

Styptic pencil
A styptic or hemostatic pencil (not to be confused with a caustic pencil) is a short stick of medication, usually anhydrous aluminum sulfate, potassium alum (both are types of alum) or titanium dioxide which is used for stanching blood by causing blood vessels to contract at the site of the wound. Before safety razors were invented, it was an essential part of a shaving kit and was used to seal cuts caused by improper shaving.[4] Some people continue to use styptic pencils for minor skin wounds from safety or electric razors.[4]

A similar substance, styptic powder, is used to stop bleeding from nails that are clipped too closely. This powder is generally used on animals, such as dogs, cats, rabbits, and birds, where the vein is found in the center of the nail.

According to Boston Poison Control Hotline (July 26, 2011) Kwik-Stop Styptik Powder for pets is safe for humans to use though it is different from styptik pencils used for people (which do not contain Benzocaine).

Why is my open cut/wound not bleeding?

Not only being in police work I am also a paramedic which is required for my position, although I do not practice as a paramedic.There are many open wounds which don't bleed for various reasons. Cuts/wounds may not bleed because they were caused by a very sharp instrument and this causes the small vessels to clamp shut on their own which stops bleeding.There are many types of open wounds including gunshots where you can see an open wound where the projectile goes in and because of the force and heat it instantly closes off the blood vessels. However, an open wound under these circumstances are most likely bleeding on the inside of the body into the abdominal or chest cavity and is a very serious wound and is life threatening.  You can "bleed out" internally with no or very little blood oozing from the entry point.A lot of amputations such as having a leg or arm severed do not bleed on the outside and are bleeding substantially on the inside and are life threatening. Just because you don't see blood oozing from a cut or wound does not mean it is not life threatening.

Describe hematopoiesis and hemostasis?

Hematopoiesis is The formation of blood or blood cells in the body. Hemostatsis is The stoppage of blood flow through a blood vessel or body part.

Why is a hemostatic plug more stable than a platelet plug?

platelet plug is formed during initial stages of blood clotting process. It is a loose plug formed simply due to aggregation of platelets at the site of injury.They simply clump to the collagen to form plug on the other hand hemostatic plug is formed by formation of stable fibrin meshwork which traps RBC and platelets. The crosslinked fibrin polymer imparts more stability to the plug.

Describe the process of hemostasis?

Hemostasis is simply the stagnation of blood that occurs with the impairment or cessation of blood fow and in itself is not a process. Hemostasis can be artificially achieved by use of a hemostat, or clamping tool, to stop the flow of blood. Hemostasis has nothing to do with coagulation of blood or platelet activity to repair leaky vessels when trauma occurs.

When you bleed. what cells rush to the wound or cut and help stop the bleeding?

This process is called haemostasis which basically has three elements: Vasoconstriction, Platelet aggregation and Clotting cascade. when you cut yourself the platelets act first and undergo changes.
Platelet aggregation can result in a 'platelet plug' that can block a small hole ,Platelets then adhere to damaged endothelium (via Von Willebrand factor) .Aggregating platelets releases arachadonic acid, converted to thromboxane A2

Calcium mediated contraction of actin and myosin results in degranulation Releases ADP which can induces further aggregation and release in a positive feedback fashion.
The rest is slightly more complicated for me.
So the old saying stands- 3 ps for stopping bleeding- pressure,patience and platelets.
Hope that helps
