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.
Each side has a relatively thin-walled chamber that receives blood returning to the heart (atrium) and a muscular chamber that pumps blood out of the heart (ventricle). Blood Flow. The flow of blood through the heart is controlled by the opening and closing of valves and the contraction and relaxation of the myocardium. Heart valves are controlled by pressure changes within each chamber and contraction and relaxation are controlled by the heart's conduction system.
