Heart development (also known as cardiogenesis) refers to the prenatal development of the heart.This begins with the formation of two endocardial tubes which merge to form the tubular heart, also called the primitive heart tube.The heart is the first functional organ in vertebrate embryos, and in the human, beats spontaneously by week 4 of development. It may be as simple as a straight tube, as in spiders and annelid worms, or as complex as the four-chambered double pump that is the center of the circulatory system in humans, other mammals, and birds. Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. The leaflets of the mitral and tricuspid valves are also supported by tough, fibrous strings called chordae tendineae. Angina symptoms may include chest tightness, burning, squeezing, and aching. Atherosclerosis Risk in Communities Study (ARIC), Coronary Artery Risk Development in Young Adults Study (CARDIA), Multi-Ethnic Study of Atherosclerosis (MESA), Systolic Blood Pressure Intervention Trial (SPRINT) Study, Trans-Omics for Precision Medicine (TOPMed) Program, NHLBI Diversity, Equity and Inclusion Statement, Customer Service/Center for Health Information. Once the blood is purified and oxygenated, it travels back to the left atrium through the pulmonary veins. These arteries branch off from the aorta so that oxygen-rich blood is delivered to your heart as well as the rest of your body. These arteries and their branches supply all parts of the heart muscle with blood. The ventricles pump blood out of the heart to the lungs and other parts of the body. The chambers are separated by heart valves, which make sure that the blood keeps flowing in the right direction. You should feel a pulsing or tapping against your fingers. The ventricles relax, and the heartbeat process starts all over again in the SA node.
