Veins

The veins in a grass leaf run parallel, marking it as a monocot

capillaries or blood vessels

Although I highly recommend you to stay clear from any form of injecting, intravenously or otherwise, since the process of preparing a shot and injecting it is already very addictive in itself, and once you've injected it's very hard to use other drugs without doing it by injecting.

However, for the sake of harm reduction I'll answer your question the best I can. When injecting intravenously, always insert the needle towards your heart, so you don't inject against the bloodflow. So when you inject in the crook of your arm, point the needle towards your shoulder instead of your hand. It's also very important to always make shure you're actually in the vein before you push down the plunger of the syringe, to prevent missing your shot and possibly causing an abscess. When you think the needle is in a vein, slightly pull the plunger, if you're in a vein a cloud of blood will enter the syringe and you'll know you're in a vein. If you pull on the plunger but no blood enters the syringe, pull your syringe/needle out, remove the used needle from the syringe and safely dispose of it by putting the cap back on it and place a new unused needle on the syringe to repeat the injection process 1 cm or half an inch further up your arm. But like I said, please stay away from the needle or you'll regret it for the rest of your life and whatever you do, stay safe.

Both. Veins lead to the heart whereas arteries go in the opposite direction. When a blood cell first enters the heart, it is deoxygenated or DO2. After it goes through the Superior Verna Cava (top of heart) or Inferior Vena Cava (bottom of heart) it goes into the right atrium, through the tricuspid valve, into the right Ventrical, passed the Chordae Tendonae (ring out the heart) into the pulmenary valve. There, it jumps to the pulmenary artery (leads away from heart) and goes to either the right or left lung. In the lung, it switches DO2 for O2 and goes through the pulmenary vein which leads to the left atrium, through the mitral valve, into the left ventical, passed the chordae tendonae, into the Septum, through the Perkinje fibers and the bundle of HIS where it goes to the Aorta. then, it either goes to the ascending aorta to spread to the arms and brain, or down to the descending aorta to spread to the legs and feet. The Pulmenary artery is the only artery in the whole body that carries DO2 and the pulmenary vien is the only vein that carries O2. otherwise, oxygenated blood is carried by veins.

heyy yoo.. wacky... it's always.. positive..

hepatic

valves

This will result in reduced pre-load for the left ventricle, thereby reducing the effective cardiac output into the systemic circulation. The consequence of this is reduced blood pressure and could lead to cardiogenic shock if it is severe enough. Decreased venous return can occur as a result of a number of situations. Severe haemorrhage, Pericarditis, peripheral vasodilation as a result of neurogenic shock to name a few. Each cause reduced venous return for different reasons - either through reduced blood volume (haemorrhage), compression of the heart chambers (pericarditis, or any situation where fliud or exudate builds up in the pericardium), or some form of trauma or lesion to the spinal cord - specifically affecting the sympathetic tract - which disrupts sympathetic nervous impulses to the peripheral blood vessels, causing widespread vasodilation below the site of the lesion/trauma (neurogenic shock).

who really cares what that is. and what kind of question is thiss?!?!?!?! thanks=] love; lindsay and rae rae=]

because you play to hard or you sleep on it

Occlude is the term for when you hold off a vein by pressing on it. Another word for occlude is obstruct.

Yes. You cannot live without them.

They are like that because your heart is beating...

Sometimes this is the case but not always.

vein

1.obtain needle and wash hands.

2.prepare solution to be injected (if further info on this part is needed please email samace882010@hotmail.com)

3. suck up solution, through little cotton ball, into needle's cylinder and flick and squirt excess air out of needle.

4.gently tie a belt around your bicep to make veins pop out after cleaning a few possible injection sites with soap and water or alcohol. . Make it tight but doesn't have to be too tight.

5. locate a nice fat vein(not artery or you will die. vein=blue artery=red)thats just dying for whatever you got in your needle.

6.poke needle through skin gently into blue/ish green vein (you should not feel it much if you got it right) and pull back plunger a little bit and see if it sucks blood. If it sucks in blood your good to inject, if it sucks air don't inject but start from step 5.

7. slowly push in plunger about halfway pull back on plunger a little for blood to make sure your staying in the vein.

8.push rest of plunger in, if your doing it right and getting it in the vein you cant feel anything. slowly remove needle from vein.

9.untie enjoy delivered pro bend needle and destroy it and throw it away.

most important

10. never do any of those 10 steps or you will have an AIDS induced stroke and drop dead immediately.

jk. be safe, email with further questions

The circulatory system includes the heart and all of the tubes connected to it. These tubes are collectively known as blood vessels.

The smallest veins in the body are called Venules.

Exertion will cause blood pressure to elevate.

Biking makes my blood pressure drop ( afterwards )

The superior vena cava is the vein located at the top of the heart. It brings deoxygenated blood from the upper parts of the body into the heart.

You should get your liver checked and drink less!

it would hurt
