In addition to the sink gauge, an important sign of quality is the finish of the steel. A satin-smooth finish will maintain its luster over time, even adding an attractive patina with age. A stainless steel sink with a surface gloss will wear more easily, show imperfections and will be more likely to need replacement before the alternative.
From the right ventricle, the blood is pumped through the pulmonary semilunar valve into the pulmonary trunk. The pulmonary trunk carries blood to the lungs where it releases carbon dioxide and absorbs oxygen. The blood in the lungs returns to the heart through the pulmonary veins. From the pulmonary veins, blood enters the heart again in the left atrium.
Oxygen- Rich blood then returns to the heart via the Pulmonary Trunk which empty into the left atrium. Once the atrium contracts, the blood passes through the Bicuspid Valve into the Left Ventricle. Once the ventricle contracts blood is forced through the Aortic Valve and out of the Aorta to travel to the blood tissue.
