The tricuspid valve connects the right atrium with the right ventricle. The semilunar valves allow the blood to flow out of the heart into the 2 main arteries (aorta and pulmonary artery). They prevent blood from returning to the heart. The top of the heart connects to a few large blood vessels. The largest of these is the aorta, or main artery, which carries nutrient-rich blood away from the heart. Another important vessel is the pulmonary artery which connects the heart with the lungs as part of the pulmonary circulation system. The two largest veins that carry blood into the heart are the superior vena cava and the inferior vena cava.

Raffia palms are a genus of about twenty species of palms native to tropical regions of Africa, and especially Madagascar, with one species also occurring in Central and South America. R. taedigera is the source of raffia fibers, which are the veins of the leaves, and this species produces a fruit called brazilia pods, uxi nuts or uxi pods. They grow up to 16 m tall and are remarkable for their compound pinnate leaves, the longest in the plant kingdom; leaves of R. regalis up to 25 m long
