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 essential components of the human cardiovascular system are the heart, blood and blood vessels. It includes the pulmonary circulation, a loop through the lungs where blood is oxygenated; and the systemic circulation, a loop through the rest of the body to provide oxygenated blood.bove is a diagram of an open circulatory system. An open circulatory system is made up of a heart, vessels, and hemolymph. This diagram shows how the hemolymph, fluid present in most invertebrates that is equivalent to blood, is circulated throughout the body of a grasshopper.
