What are the little veins called that are close to the skin that start with an A?
The smallest blood vessels are called capillaries. The next largest are veins. The largest are arteries. Arteries are deeper in the body than veins and capillaries, which are closer to the skin. Some veins are also deep within the body. There is no type of blood vessel starting with the letter "A" that is close to the skin.
Does aetna cover varicose vein removal?
That depends on the specific plan and so the only real way to know is to call them.

How do the arteries of someone with atheroscierosis differ from healthy arteries?
People who have atherosclerosis have lipid deposits or fat in their arteries. The fat makes carrying blood to the cells of the body difficult. You may have a heart attack or stroke depending on which artery is clogged.
Where is the location of the left pulmonary vein?
The left pulmonary vein carries oxygenated blood from the left lung to the left atrium of the heart. The pulmonary arteries and veins are the only ones which are "opposite" as the rest of the bodies veins and arteries. Veins normally carry unoxygenated blood from the body back to the heart/lungs. Arteries normally carry oxygenated blood to the body from the heart. Pulmonary arteries carry unoxygenated blood from the heart to the lungs and pulmonary veins carry oxygenated blood from the lungs back to the heart.
i don't know im bored
What makes the pulmonary veins and arteries more confusing than other veins and arteries?
We usually think of arteries as the vessels that carry oxygenated blood to the body, and we usually think of veins as the vessels that carry spent blood back to the heart/lungs. But the vessels around the heart can be a little different. It is an artery that carries spent blood from the heart to the lungs (where they get re-charged with oxygen), and then it is a vein that carries this oxygenated blood back to the heart to then be pumped out to the body.
To clear it up, realize that if a vessel is carrying blood out of the heart chambers, it is an artery. If the vessel is carrying blood back to the heart chambers, it is a vein. It is not oxygen content that defines a vessel as an artery or a vein.
The coronary arteries are vessels that are carrying oxygenated blood out of the heart chambers and into the heart muscle itself; they are not carrying blood into the chambers for pumping. So they also are indeed arteries and not veins.
What do you do about blood clot hanging from your hamsters bottom?
First you should take it to a vet!!! Most likely PetSmart or the nearest small animal vet.
What is a purple vein on your balls?
A purple vein on the testicles can be a normal anatomical feature, as veins may appear more prominent due to factors like temperature changes, physical activity, or increased blood flow. However, if the discoloration is new, persistent, or accompanied by pain or swelling, it could indicate a condition such as a varicocele or other vascular issue that should be evaluated by a healthcare professional. It's important to monitor any changes and consult a doctor for personalized advice.
Veins are often formed from hot water solutions.?
Veins are mineral-filled fractures in rocks that typically form from hot water solutions, a process known as hydrothermal mineralization. As heated water, rich in dissolved minerals, moves through cracks and fissures in the Earth's crust, it cools and precipitates minerals, leading to the formation of vein deposits. These veins can contain valuable minerals such as gold, silver, and copper, making them significant for mining. The temperature and pressure conditions, along with the chemical composition of the solutions, influence the types of minerals that crystallize in these veins.
What is the name of the vein on the thumb side of the arm?
The cephalic vein drains the lateral side of the arm.
What are the complications resulting from a blowed vein?
Complications from a blown vein, or venipuncture injury, can include bruising, swelling, and pain at the site of the injury. In some cases, it may lead to a hematoma, where blood accumulates outside the blood vessel, causing further discomfort. Rarely, a blown vein can result in phlebitis, which is inflammation of the vein, or the formation of a blood clot. Prompt care and monitoring are essential to manage these complications effectively.
How can you tell you are in a vein when drawing with a butterfly needle?
You can tell you are in a vein when using a butterfly needle by observing a few key signs. First, you should feel a sudden give or a slight drop in resistance as the needle enters the vein. Additionally, you may notice blood flash back into the chamber of the needle or the tubing, indicating successful venous access. Finally, if the blood flows easily when you gently pull back on the plunger, it confirms that you are properly positioned within the vein.
Why does thrombi form in the arteries?
A thrombosis or thrombus is a blood clot. They can develop in any vein, but especially in the femoral veins of the thighs and in veins located in the calves. While many health issues can result in a clot developing, the most common reasons are a combination of these facts:
- inability or failure to move about frequently; inactivity, including jobs that require sitting for long hours
- inability or failure to stay adequately hydrated
- high cholesterol
- high blood pressure
- any circulatory condition in which the blood vessels become narrowed
A clot usually begins with RBCs becoming sticky, such as when the person is dehydrated. The sticky RBCs attach to a vein wall. As more blood swooshes by and past the sticky spot, more RBCs also begin to stick to that spot. A vein may have just a bump of sticky RBCs, or the clot can fill half or more of the vein lumen (the hollow part of the blood vessel).
IF the clot stays together, it can block off the flow of blood completely. The limb below the clot might get hot, red, painful, swollen--- or there may be no symptoms. If severe, the entire limb may swell. The clot may form a clothesline-like structure, filling a vein for many inches or even feet.
IF a portion of the clot breaks off, it becomes an embolus. It can then travel to the heart, lungs, or brain where it can cause considerable damage or even death.
Penetrating injuries to the neck can damage the jugular vein. Sometimes it also get damaged with bleeding during Central venous line, a procedure which involves cannulation of the neck veins for feeding or monitoring.
What is the job of arteries and arterioles?
The function is it carries blood away from the heart, and the structure of the wall is is usually very thick, there is 3 layers of the wall. The first is Epithelial cells, the second is muscle tissue, and the last is a flexible connective tissue.
