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.
The Heart. Blood moves through the arteries and veins in only one direction. The opening and closing of valves in the heart's chambers work in such a way to make certain that blood is carried throughout the body in a circle known as circulation.t takes the heart less than one minute to pump blood to every cell in the body. In fact, six quarts of blood can fully circulate throughout the body at least three times within that minute. That totals thousands of round trips each day.
