The watt-hour (symbolized Wh) is a unit of energy equivalent to one watt (1 W) of power expended for one hour (1 h) of time. The watt-hour is not a standard unit in any formal system, but it is commonly used in electrical applications. An energy expenditure of 1 Wh represents 3600 joules (3.600 x 103 J). To obtain joules when watt-hours are known, multiply by 3.600 x 103.
The blood flow from the heart to the right arm is as follows: The blood is pumped from the heart through aorta. It then passes through the brachiocephalic trunk, through the subclavian artery and then it goes through the axillary artery.he blood then flows to the left ventricle through the bicuspid valve. Then it goes to the Aorta through the aortic semi-lunar valve and travels to the rest of the body. After the blood is done in the body in goes to the superior and inferior vena cava and it starts all over again.
Starting in the right atrium, the blood flows through the tricuspid valve to the right ventricle. Here, it is pumped out the pulmonary semilunar valve and travels through the pulmonary artery to the lungs. From there, oxygenated blood flows back through the pulmonary vein to the left atrium.tarting in the right atrium, the blood flows through the tricuspid valve to the right ventricle.
