Bright red blood that spurts out comes from severed vein or severed artery?
It comes from an artery. Arteries carry OXYGENATED blood away from heart. This oxygenated blood is bright red. The Arterial system is on the high pressure side of the heart. The pressure changes as the heart contracts and then expands and refills (a heartbeat). When an artery is punctured the blood will spurt with every heartbeat.
What is the basic difference between arteries and veins?
Arteries carry oxygenated blood from the heart and veins carry de-oxygenated blood back to the heart.

What is the direction of blood flow in veins?

Why do i have a sharp pain on pubic bone when trying to cross legs at 38 weeks pregnant?
Because the ligaments in your pelvis would much rather you didn't! Crossing your legs (and adopting various other positions) will put stress on your pelvic girdle, especially your symphysis pubis at the front. Try keeping your pelvis symmetrical - when standing, keep hips level; when lying, try being on your side with a pillow between your knees; when sitting, stay upright with both feet on the floor. You may have a mild case of SPD but it's probably just typical pregnancy discomfort so late in your pregnancy. Good luck, not long to go now...

How would severe bleeding from a major veins affect heart rate and heart output?
Your cardiac output is equal to your stroke volume (amount of blood being pushed out every time your heart beats) multiplied by your heart rate. Your cardiac output equals the amount of circulating blood needed to function at a given time.
Your body will try to compensate for any changes in the amount of blood in your system, therefore your body will always try to maintian cardiac output. With any type of major bleeding, your stroke volume will decrease. In order to maintain your cardiac output, your heart rate will increase. For example:
(Stroke Volume of 50mL) x (Heart Rate of 60) = Cardiac Output of 300
With major bleeding, the decrease in stroke volume will require an increase in heart rate:
(Stroke Volume of 25mL) x (Heart Rate of 120) = Cardiac Output of 300
You can see that the amount of blood decreased in half for every heart beat (50mL to 25mL), so the heart has to beat twice as fast (60 beats per minute to 120 beats per minute) to make up for the blood loss.
Veins have no reproductive organs, so no they cannot reproduce per se.

Why the blood come out from my mouth when im feel stress?
Consult a doctor right away, it could possibly be an ulsur. Ulsurs can lead to death almost all the time and they are mostly caused by too much stress. An ulsur is basically like a balloon of blood clotted up in your stomach (most of the time) and if it breaks, you would most likely die from internal bleeding. I know this from experience.

How can you end up brusting a vein when getting your tongue periced?
down the center of you're tongue, there is a major artery that splits into hundreds of capillaries. The needle going through a capillary is not going to hurt anything, but if the piercing goes too far back on your tongue you can split the artery open, causing blood to spill out rather than feed the cells in the end of your tongue. Let a professional do it.
