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.
It begins after the aortic valve where blood has left the heart, and ends in the superior and inferior vena cavae that bring deoxygenated blood from the organs back to the heart. Summary: The heart pumps blood through the coronary circulation to supply oxygen to the heart itself, and through the systemic circulation to supply the entire body other than the heart. Deoxygenated blood from all parts of the body enters into the heart through the superior and inferior vena cava. The blood enters the right atrium. When the right atrium contracts the blood is pushed into the right ventricle through the tricuspid valve.
