The Federal Stafford Loan has a fixed interest rate of 6.8% and the Federal PLUS loan has a fixed rate of 7.9%. This loan calculator also assumes that the loan will be repaid in equal monthly installments through standard loan amortization (i.e., standard or extended loan repayment).
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 for each circulation, and with both a systemic and a pulmonary circulation there are four chambers in total: left atrium, left ventricle, right atrium and right ventricle.he circulatory system of the lungs is the portion of the cardiovascular system in which oxygen-depleted blood is pumped away from the heart, via the pulmonary artery, to the lungs and returned, oxygenated, to the heart via the pulmonary vein.
Pulmonary Circulation. The pulmonary circulation carries the blood to and from the lungs. In the heart, the blood flows from the right atrium into the right ventricle; the tricuspid valve prevents backflow from ventricles to atria.The right ventricle contracts to force blood into the lungs through the pulmonary arteries.n the lungs oxygen is picked up and carbon dioxide eliminated, and the oxygenated blood returns to the heart via the pulmonary veins, thus completing the circuit. In pulmonary circulation, the arteries carry oxygen-poor blood, and the veins bear oxygen-rich blood. Sections in this article: 1  Introduction.
