How important are fluids? Fluid replacement is probably the most important nutritional concern for athletes. Approximately 60% of your body weight is water. As you exercise‚ fluid is lost through your skin as sweat and through your lungs when you breathe. If this fluid is not replaced at regular intervals during exercise‚ you can become dehydrated. When you are dehydrated‚ you have a smaller volume of blood circulating through your body. Consequently‚ the amount of blood your heart

Chapter 3 Fluid Statics: Definitions Statics: ∑F = 0. In statics we have only pressure as surface force and weight as body force. Thus‚ when fluids are still‚ the pressure is balanced by the fluid weight. No relative motion between adjacent fluid layers. Shear stress is zero Only _______ can be acting on fluid surfaces Gravity force acts on the fluid (____ force) Applications: Pressure variation within a reservoir Forces on submerged surfaces Buoyant forces 9/4/2013 1 Pressure Pressure is defined

Kidney Failure Human health has been misdiagnosed and misunderstood for centuries "until the evolution of the medical field in the late 1800s which led to a rise in the average life expectancy from thirty-six to a whopping seventy-eight"1. Then specialists started to identify the structure and the function of each organ. That’s when they found how some organs are important that the human body cannot work properly without them‚ such as heart‚ kidneys and lungs. As well as others that can be cut

We note that the fluid at both points is open to the atmosphere (and thus P1 = P2 = Patm)‚ and the fluid velocity is 6 ft/s at point 1 and zero at point 2 (V1 = 6 ft/s and V2 =0). We take the free surface of the river as the reference level (z1 = 0). Then the energy equation for a control volume between these two

What is Kidney Cancer? Brittany Elliott University of Phoenix Cancer is one of the most devastating chronic diseases in our world today. Cancer of any form can be deadly‚ and often is not detected early enough for effective treatment. It can invade any organ‚ any part of the body‚ at any time‚ without warning or cause. The most common type of cancer that affects your kidneys is called Renal Cell Carcinoma. The term “renal” refers to kidneys‚ and “Carcinoma” is another term for cancer.

. Update Article NSAIDs and Kidney P Ejaz‚ K Bhojani‚ VR Joshi* Abstract NSAIDs are commonly used drugs. Even with the advent of selective COX-2 inhibitors‚ nephrotoxicity still remains a concern. The adverse effects of NSAIDs are mediated via inhibition of prostaglandin synthesis from arachidonic acid by non-specific blocking of the enzyme cyclooxygenase leading to vasoconstriction and reversible mild renal impairment in volume contracted states. When unopposed‚ this may lead to acute tubular

A kidney stone is a hard piece of material that is formed from substances in the urine and develops in a kidney. These hard stones may often come loose and move down the urinary tract. If it is small enough‚ it can pass through in the urine with little pain. However‚ the bigger kidney stones can lodge somewhere in the urinary tract‚ get stuck‚ and cause a lot of pain. It can also obstruct the flow of urine. This article explains what causes them‚ and describes several different treatments for them

Properties The density of water is given to be = 1000 kg/m3. Analysis The mass of the water in the tank and the total mass are mw =V =(1000 kg/m3)(0.2 m3) = 200 kg mtotal = mw + mtank = 200 + 3 = 203 kg Thus‚ 1-14 The variation of gravitational acceleration above the sea level is given as
