Veins

This is the entire hepato-duodenal ligament. Temporary occlusion of the hepatic artery and portal vein can be done quickly by placing a vascular clamp around the hepatic pedicle.

Varicose veins can develop in the deep veins also. Varicose veins in the superficial veins are called primary varicosities, while varicose veins in the deep veins are called secondary varicosities.

Most veins have low-pressure circulation in them, which is why they have a series of backcheck valves to allow blood to flow in only one direction back towards the heart. It should be noted that commonly taken blood pressure readings are actually measuring arterial blood flow only (120/80), since venous pressure becomes very low closer towards the heart.

The inferior vena cava

The length of veins in the human body can range from 50,000 to 100,000 miles, depending on which anatomy textbook you're referencing (this also depends, of course, on the age of the body).

Phlebostenosis

Whereas facial spider and reticular veins are easily removed by topical lasers, large and bulging leg varicose veins can only be removed by endovenous laser techniques, such as Endovenous Laser Treatment (EVLT). The procedure involves inserting a laser fiber inside a vein, guiding it in the vein with the help of Ultrasound Imaging, and then applying laser pulses. It is usually performed in a doctor's office using local anesthesia only.

Your feet is the most dependent part of your body; i.e. gravity tends to pull down the blood, and tend to pool in your feet. If you were to raise your feet above your heart level the veins would start to collapse.

it has many more capillaries...if you were to wrap all of your capillaries around earth it would wrap around twice

The only jugular i know of is the jugular groove, this is found on a horse. The jugular groove is just a bit further up from the breast and a bit further down from the horses windpipe.

It is a vein. It is one of the main ones and carries oxygen to the brain and head. If it is cut, you can bleed to death in a couple of minutes.

It is sometimes used in the phrase, "Go for the jugular!" It means go in for the kill, show no mercy.

Blue stomach is a urban legend phrase. It is said one will get a blue stomach if their dinner date flakes on you and leaves you so hungry that it hurts.

Spider veins, also known as varicose veins can be unsightly and embarrassing. They are small blood vessels that appear red or bluish in color and are often in a web or matted pattern. They are typically painless; however they can be accompanied by a slight burning sensation due to long periods of standing and pressure. Some of the causes of spider veins are genetics, pressure on the feet and legs, sun exposure, and injury. There are treatments that can assist in removing spider veins.

Spider Vein Laser Removal

As with any medical procedure there are pros and cons. The most common treatment for spider veins is laser removal. The doctor will give you a pair of goggles to wear to protect your eyes. Laser removal is not always a pain free process. Although there are no needles, the procedure is known to sting some and there is a vague smell of burning. Doctors can give you a local anesthesia to ease or dull the pain. Laser removal is a light that breaks down the veins. This is a procedure that has to be repeated in order to achieve the desired results. After the area is tagged with the laser, it will become red, itchy and irritated. Typically a bandage and ointment is applied prior to leaving the doctor’s office. There can be some discoloration from the lasers; however there is a discoloration cream your doctor can give you to aid in lightening the area. Most spider vein laser treatments are done In a short period of time. Typically only taking an hour or so. Most patients have theirs done during their lunch breaks. The amount of treatments needed is going to be determined by your doctor. Some spider veins, depending on the severity of them could take more than several treatments and visits to the doctor. They can also be quite costly. Some sessions can cost anywhere from $350 to $500 per session.

These are called Haemorrhoids or they are often referred to as 'piles'

Vena cava

The spleen produces lymphocytes. As blood flows through the spleen, lymphocytes attack or mark pathogens in the blood. If pathogens cause an infection, the spleen may also release lymphocytes into the bloodstream.

The heart pumps blood from the left ventricle through the aortic semilunar valve into the Aorta.

Spider veins: A group of widened veins that can be seen through the surface of the skin. Their wheel-and- spoke shape resembles a spider. Also known as spider telangiectasia.

Varicose vein: A dilated (widened) tortuous (twisting) vein, usually involving a superficial vein in the leg, often associated with incompetency of the valves in the vein. These visible and bulging veins are often associated with symptoms such as tired, heavy, or aching limbs

No, arteries have thicker walls because blood pumps through the arteries around the body, therefore blood pumps through arteries which a high pressure so thick walls are needed. Blood goes through veins with a lower pressure as they lead back to the heart to be oxygenated.

It cant be visible because it is hidden behind your throat.

the largest vein of two veins

The Largest Vein in the Heart is the Coronary Sinus, which runs in the atrioventricular groove around the posterior and lateral aspect of the Right Atrium.

The Second largest vein in the heart is the Great Vein which lies anteriorly and runs with the Left Anterior Descending or Anterior Interventricular Artery, commonly referred to as the LAD or widow maker.
