Epilating exposes deeper parts of the mesodermal tissue, increasing susceptibility to infection. An individual with spider veins, varicose veins, or warts may obtain an infection directly in his or her bloodstream.
Blood vessels that bring blood towards the heart are called veins. The veins that are directly connected to the heart are the superior and inferior vena cavae and the pulmonary veins.
Intravenous is a route of administration where the drug or substance is injected directly into the veins.
Blood from the pulmonary veins enters the left atrium, is then pumped to the left ventricle, and then to the rest of the body through the aorta.
