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.
After the blood receives oxygen, it returns to the left side of the heart, the left atrium. After collecting in the left atrium, it is pumped into the left ventricle, and from there it is pumped into the aorta, the largest blood vessel in the body. From the aorta, blood courses throughout the body through its arteries. For blood to go in only one direction, forward, it must pass through the heart valves, which function as one-way doors, opening and shutting with each beat of the heart. Just as there are four chambers to the heart, there are four heart valves.
