The Body: Circulatory System

Understanding how the body works is key to being able to defend it appropriately. The reason it is important to understand how the circulatory system works and where the major arteries and Veins are is key when defending against edged or sharp weapons.

For our purposes the 3 major groupings we need to be concerned about:

Neck & Throat

Artery Vein
Major:  Carotid Artery Major: Jugular Vein

Hands up is an important concept, as it is to protect our head and neck. When it comes to bladed weapons a well place slash or stab could severe these and cause a bleed out within as little as 6 seconds. These are also the blood pathways being cut off during a rear naked choke. Empty handed we mostly have to worry about being hit in the head or face, but with blades with cannot forget to protect the neck and throat as well.

Arms & Shoulders

Artery Vein
Major:  Brachial Artery

Major: Subclavian Artery

Minor: Radial Arteries

Major: Basilic Vein

Major: Subclavian/Axillary vein

Minor: Radial Veins

The brachial artery and its pairing veins run under the bicep and armpit and are generally easy to defend as they are quite deep but a well place targeted stab could cause a quick and fatal blow. Also, the subclavian artery and matching veins are located just under your clavicle bone. Stabs to this region could also target the heart and lungs depending on the length of the blade. As these are closer to the neck an missed ice pick attack to the head cut slide lower and end up in these fatal places. We also have our radial arteries and matching veins, these run in the soft tissue of the forearm. We often think these will be fatal wounds if cut or slashed but generally (barring extreme damage) bleeding can be stopped with good direct pressure. Never the less in the presence of a bald you should avoid exposing the soft sides of your arms and palms.

Legs & Groin

Artery Vein
Major:  Femoral Artery Major: Femoral Vein

The good news is that they are deep in the tissue and hard to reach most of the time. The bad news is if they are severed it can be exceptionally difficult to stop the bleeding without immediate advanced medical attention. Because of this, we choose to avoid exposing it as much as possible when a blade is out. This is one of the many reasons we prefer a low line sidekick as opposed to a front kick when dealing with knives. Although both can be acceptable options.
