Types of arteries and veins. There are two types of arteries in the body: Pulmonary and systemic. The pulmonary artery carries deoxygenated blood from the heart, to the lungs, for purification while the systemic arteries form a network of arteries that carry oxygenated blood from the heart to other parts of the body.rteries carry oxygenated blood (with the exception of the pulmonary artery and umbilical artery). Veins carry deoxygenated blood (with the exception of pulmonary veins and umbilical vein).
[Oahu:6 Maui:8 Kauai:7 Big Island:10] The Kona coast of the Big Island tends to have the clearest water and offers the best snorkeling in Hawaii. Maui and Kauai both have several prominent snorkeling locations, although Kauaiâs best snorkeling is more subject to ocean conditions.
Hi. We love to snorkel and have traveled to the hot snorkel spots in the Caribbean. We've been to Grand Cayman, Bonaire, and St. John. I've never been to the Dominican Republic but have been to Jamaica 3 times. We snorkeled a few times at Doctors Cave beach in Montego Bay. We were so surprised to find the snorkeling there really good! I find with snorkeling that conditions are always changing.
