I assume you mean with a needle.

It will hurt like hell, blood will come out rapidly (possibly with enough force to push the plunger back automatically), and you need to immediately apply pressure and treat the wound or you could be in some serious trouble.

Arteries have thicker walls and are deeper, so you will most likely know if you hit an artery instead of a vein. Do NOT inject into your artery, this is very dangerous.

Calcification of the non aneurysmal aorta means that a plaque like substance has built up on the artery wall. This may or may not be a serious medical problem. Only a medical professional will be able to know for sure.

Low-Density Lipoprotein

The function of the coronary artery is to supply the cardiac muscle with oxygen and other nutrients.
The left coronary artery supplies the left side of the heart.
The left coronary artery supplies the left side of the heart.

Femoral

The more pressure it uses, the thicker the walls will be.

Veins have very low pressure which means they have thin walls and vice/versa for arteries which have a higher pressure and thicker walls than veins.

elastic

It is a large artery.

Body fluids are things like sweat, tears, blood, urine, CSF, mucus, genital secretions, breast milk; just about anything that is a part of or can come out of the body.

low blood pressure - need more food, like sugars. high blood pressure - the opposite

The left coronary artery is an artery which arises from the base of the ascending aorta, passing posterior to the pulmonary trunk and inferior to the left auricle. The left coronary artery is divided into small branches to supply nutrients to the left side of the heart. Its major branches include the circumflex branch and the anterior interventricular branch.

anterior interventricular branch you're welcome!!!!

Yes. If you cut it, it starts major bleeding and it hurts.

Heart Attack

It will bleed more profusely and it will pulse out as the arteries are coming from the heart

NO.Portal vein is a vein,but is an important supply to liver which carries nutrients absorbed from gastrointestinal tract and spleen.Meseteric arteries are the arteries supplying intestine.On the other hand superior mesenteric vein is a tribuatory to portal vein.

Acute onset of renal vein thrombosis at any age causes pain in the lower back and side, fever, bloody urine, decreased urine output, and sometimes kidney failure

Right- Brachiocephalic artery

Left- subclavian artery

a completely clogged coronary artery is one the things that causes heart attacks (myocardial infarctions)

The lungs (pulmonary means lung).
