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 atria and ventricles perform the pumping action, while the valves regulate blood flow. When the valves work properly, blood flows in only one direction. Both sides of the heart work together to ensure there is always an adequate supply of oxygen-rich blood available to the rest of the body. On the right side of the heart, oxygen-poor blood enters through the inferior and superior vena cava before emptying into the right atrium. The blood then travels from the right atrium through the tricuspid valve and into the right ventricle. Blood leaves the right side of the heart via the pulmonic valve and empties into the pulmonary artery. Oxygenated blood travels from the pulmonary vein to the left atrium. Then it flows through the mitral valve and into the left ventricle. Finally, it passes through the aortic valve and into the aorta.
