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.
Each beat of the heart pumps blood into both the pulmonary and system circulation system. This provides a continuous flow of oxygenated blood to the body's organs, tissue and cells. It also provides a continuous flow of deoxygenated blood to the lungs where the red blood cells pick up oxygen.
