Exodus-the second book of the Old Testament: tells of the departure of the Israelites out of slavery in Egypt led by Moses; God gave them the Ten Commandments and the rest of Mosaic law on Mount Sinai during the Exodus.
Pulmonary circulation is the movement of blood from the heart, to the lungs, and back to the heart again. Deoxygenated blood leaves the heart, goes to the lungs, and then re-enters the heart; Deoxygenated blood leaves through the right ventricle through the pulmonary artery.
The heart pumps oxygenated blood to the body and deoxygenated blood to the lungs. In the human heart there is one atrium and one ventricle each for systemic and pulmonary circulation, with four chambers in total: left atrium, left ventricle, right atrium, and right ventricle . The right atrium is the upper chamber of the right side of the heart.
