Shingles, also known as zoster or herpes zoster, is a painful skin rash caused by the same virus responsible for chicken pox: the varicella zoster virus. Even if you had chicken pox in the past, you can still contract shingles.aused by the herpes virus, the earliest symptoms of both conditions include headache, fever, a general feeling of malaise, sore throat and swelling of the face. Chicken pox is very common in children, being actually a children's disease. It is very contagious and it is actually nothing but a viral infection.
The pulmonary vein is the vessel transporting oxygen-rich blood from the lungs to the left atrium. A common misconception is that all veins carry de-oxygenated blood. It is more appropriate to classify veins as vessels carrying blood to the heart.
Anyway, blood from the Right Atrium goes into the Right Ventricle from which the blood is pumped to the lungs via the Pulmonary Artery to get oxygenated (i.e. to get oxygen). Once oxygenated at the lungs, the blood returns to the heart via the Pulmonary Veins, and is dumped into the Left Atrium.
