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 blood in a two-step process. The atria pump blood into the ventricles and then the ventricles pump blood out of the heart. Chambers of the heart fill with blood during a relaxation phase (diastole) and eject blood during a contraction phase (systole). Atrial systole precedes ventricular systole.
