Question #1 Pre-load can be defined as the degree to which cardiac (heart) muscle cells extend before contraction in the heart. Pre-load is one of the factors that affect the stroke volume. It directly relates to stroke volume. The way it works is that a rise in venous return to the heart raises the end diastolic volume of the ventricle which causes the muscles fibers to stretch thus increasing preload. Also‚ it increases the force of contraction of the ventricles making the heart to discharge

adipose capsule is a middle layer of adipose (fat) tissue that cushions the kidneys. The renal capsule is an inner fibrous membrane that prevents the entrance of infections. Regulation The loop of Henle of juxtamedullary nephrons is the apparatus that allows the nephron to concentrate urine. The loop is a countercurrent multiplier system in which fluids move in opposite directions through side-by-side‚ semipermeable tubes. Substances are transported horizontally‚ by passive or active mechanisms

Nephron Sparing Transcatheter Renal Artery Embolization in Trauma Patient Introduction: Acute renal hemorrhage is a common medical emergency‚ which can lead to hemorrhagic shock and eventual death. Complete nephrectomy is used in emergency surgery and is associated with significant postoperative complications. Employing nephron sparing super-selective Transcatheter renal artery embolization techniques can be used to treat acute renal bleeding disorders eliminating need for exploratory laparotomy

With the urine samples given to us by the five patients we tested the amounts of glucose‚ amino acids‚ urea‚ and salts in urine. To test this we used different chemicals that would react with one of the four items above showing either a high concentration or low concentration within the urine. By using a solution called silver nitrate we could test whether or not salt was present in the urine. If the urine turned a cloudy white after adding the silver nitrate the urine had a high concentration of

the inner section as well as chambers are visible. Both the sheep and the pig kidney have the distinctive kidney bean shape. The cortex of the kidney is striated. The next layer is the the medulla. This area appears quite fatty. The area where the nephron and and renal arteries are located. The white section‚ in the center of the kidney is the renal pelvis. There is a hole identified as the opening to the ureter which is where the urine would drain from the kidney. At the edge of the renal pelvis are
