Blood from the body flows: 1  to the superior and inferior vena cava, 2  then to the right atrium. 3  through the tricuspid valve. 4  to the right ventricle. 5  through the pulmonic valve. 6  to the pulmonary artery. 7  to the lungs.
From the UPS docs: UPS Address Validation uses U.S. Postal Service guidelines to thoroughly check the city, state and postal code of every shipment. UPS provides up to ten alternate addresses, including an accuracy rate that lets your customers know how closely the address they entered matches the suggested address.
UPS and FedEx both use the USPS as their backend to deliver address validation results. This means that all three carrires are going to provide almost identical results. The USPS is the canonical source of truth for U. S. addresses.
