Veins
Veins are thin blood vessels that carry blood from various body parts to the heart. These have valves in them to prevent back flow of blood.

Why are vein important in blood circultion?
Veins are the vessels that carry de-oxygenated blood back the heart. Without the venous system, there would be no way for blood to return to the heart, and circulation would not be complete.
Is laser vain treatment a good idea if I have severe spider veins?
It should be. However, be aware that there are risks of complications, such as bruising and bleeding at the site of surgery.
Veins are vessels which carry blood towards the heart. In addition to blood itself veins carry liquid plasma and it constituent factors.
A vampirism paraphilia. A true vampire paraphilia should be distinguished from a goth or emo fashion culture. In true vampirism the person is attracted to the blood vessels of their "victim" and/or the actual drinking of their blood. True vampirism as a paraphilia is rare.
ESWL is to break the kidney stones and to know whether you actually have it, you need KUB in the first place. KUB and IVP are diagnostic procedure while ESWL is therapeutic.
Because the but diet and lack of exercise lieds to accumulation of lipids and later on the atherosclerotic plaque keep increasing leading to a platelet segregation. And when the rupture of plaque occurs might lead to a non-occlussive thrombus = unstable angina or occlusive thrombus= myocardial infarction, ending with acute coronary syndromes.
The answer is: c. Capillaries and arteries are similar in size.
What are the function of pulmonary vein?
Pulmonary viens conduct blood away from the lungs.This blood is carried to the right atrium of the heart.
What condition would you have to need to undergo coronary artery surgery?
You will need coronary artery bypass surgery if you suffer from coronary artery disease. The procedure works by relieve angina and by grafting arteries and veins to the coronary arteries.
Veins transport deoxygenated blood from the body to the heart. They also prevent the backward flow of blood. The pulmonary vein, as an exception, transports oxygenated blood from the lungs to the left atrium of the heart.
Does medial cubital vein contain valves?
I would think it would have to otherwise you wouldn't be able to get venous return to the subclavian.
Which heart chamber receives blood from the pulmonary veins?
The left atrium receives oxygenated blood from the pulmonary veins
Is there a finger that has a vein that leads directly to the brain?
The venous system is a highly-branched network of veins all over the body and brain that returns blood back to the heart for 'nutrient re-fill' after this blood has been stripped of its nutrients by body tissues. Anatomically speaking, you can trace any vein in the human body to any other vein in the human body (including a vein from your finger to your brain). However, blood does not run directly en route from any vein in any finger to the brian. Blood in the veins of your fingers (which are called your digital veins), runs from your digital veins and branches to your Ulnar and Radial veins of your arms (mainly), these two veins then branch to form your axillary vein (near your armpit). The next and last stop for blood is the superior vena cava, a large vein that dumps all of the blood that is returning from the top half of the body into the right atrium of the heart for nutrient refill.
Long story short: Anatomically..yes there is. Does blood go from your fingers to your brain? No.
I hope this provides you with your answer as well as some helpful information
Has the vein burst in your wrist?
The nerves that serve the body aren't particularly strong, and they can be injured or broken from too much stretching, pressure, or cutting. If the nerve is damaged through excessive stretching or pressure, it may stop working and no longer carry messages to and from the brain. The tissue surrounding the nerve, however, may be undamaged. If the nerve is cut, the nerve along with its covering may both be broken. In any injury, the nerve's ability to carry messages may be interrupted, and this can stop muscles from working or can cause loss of feeling in the part of the body served by that particular nerve.
If a nerve fiber breaks, the end of the nerve that's farthest from the brain dies. If the insulation isn't damaged, it becomes an empty tube once the nerve completely dies. The end of the fiber closest to the brain will not die, however. In fact, it may even start healing on its own, possibly growing back through the uninjured tube until it reaches a muscle or a sensory receptor.
If both the nerve and its surrounding tissue are cut and the nerve is not repaired, a condition known as a neuroma may result. In such cases, the nerve fibers try to grow back but because they don't have a good insulating tube in which to grow, they end up forming a ball at the site of the original cut. The neuroma that results can be painful and can even cause an electrical sensation when it's touched.
Does the popliteal vein circle in front of the knee?
No - it runs up the back of the knee and provides blood to the thigh and calf.
Does it hurt if you have a varicose vein?
I started to get varicose veins at around the age of 10 years, like some other people on my fathers side of my family (including my father).
They began to hurt about 19 years later - I felt no sensation at all associated with them until I was 29, although I could see that they were becoming steadily larger and more pronounced.
At 30 I was told I had developed "phlebitis" (manifested as red lump and soreness in one place on the inside back of my calf, where there were some varicose parts of the veins) and given an operation to remove the veins "saphenous avulsion".
This operation made my leg look better, although not all the varicose veins were gone. The soreness stopped completely. The pain stopped completely.
After this operation, I felt no sensation associated with my veins again for about 10 more years - although, as always, I could see the residual varicose veins steadily becoming larger, and new ones appearing. Then they started to hurt again at around age 40. Now I am 47 and the amount of pain I am getting from the veins, while not great, is gradually increasing (and the veins are continuing to become larger, and new varicose areas developing).
So, in summary, I am now 47, have had visible varicose veins for 38 years, have had one operation for them. During the years that I have had visible varicose veins, they have hurt in total for about 8 years and not hurt at all for about 30 years.
According to Duke Heath clinic they only get worse

What is the rate of deep-vein thrombosis complication after cesarean section?
The risk for developing a deep-vein thrombosis is three to five times higher in patients undergoing c-section than vaginal delivery.
Do veins never carry oxygen-rich blood?
The term "vein" describes vessels leading to the heart. The Pulmonary Veins are the only veins that carry oxygen rich blood. They carry the blood from the lungs to the heart.
How many veins are there in a dog?
There are enough blood vessels in the human body that if you placed them end to end, they would go around the equator 4X. Since half are veins and half are arteries, then veins only go around 2X. You would need to know the size of the dog. The size of a man (average) is 6 feet tall and 190 pounds.
What is the Function of Superior Vena Cava?
The superior vena cava brings de-oxygenated blood from parts of the body higher than the heart and returns the blood to the right atrium.
Difference between veins and lymphatic vessels?
Comparison between Lymph Vessels and Veins.
- Similarities.
- both have an interconnecting network of progressively larger vessels;
- both transport fluids to the heart;
- the larger lymph vessels have the same structure as veins, i.e. their walls have the same three layers;
- both have semi-lunar valves to prevent any backward flow of blood;
- the flow of fluid is slow but steady and at low pressure;
- the fluid is deoxygenated;
- like blood capillaries, the walls of lymph capillaries are composed of a single thin layer of squamous endothelium.
- Differences.
- the walls of lymph vessels are musch thinner and more transparent;
- the muscle layer in lymph vessel is much less developed, but there is more connective tissue;
- blood capillaries form a continuous, open circuit, whereas lymph capillaries end blindly in the tissues;
- lymph capillaries have a larger diameter than blood capillaries;
- lymph capillaries have walls which are more permeable than the walls of blood capillaries. Consequently, larger molecules (such as proteins) are able to diffuse through them.
