PART 1 Exam #1 Review Renal Overview: * Renin-angiotensin aldosterone system (RAAS) regulates renal blood flow. * ACUTE RENAL FAILURE -rapid decline in renal function with progressive azotemia. * AZOTEMIA An excess of metabolic waste products in the blood Urea Nitrogen and Creatinine * OLIGURIA Urine Volume less than 400CC/24 hours for a non-trauma‚ non-surgical adult. * ACUTE TUBULAR NECROSIS (ATN) Clinical syndrome of ARF secondary to ischemia or toxic injury

The Excretory System The importance of the excretory system The excretory system involves a process which removes unwanted products from the body’s chemistry. In general‚ excretion is the process of separating wastes from the body fluids and eliminating them. Examples include the removal of carbon dioxide in the air we exhale‚ and unwanted nitrogen in sweat‚ nails and hair. Explain the various methods of excretion in the human body There are four (4) organ systems which are responsible

Describe two variables that affect the rate of diffusion. ___ Two variables that affect rate of diffusion are molecule size and plasma membrane composition. A larger molecule will diffuse more slowly than a smaller molecule. The lipid content of the plasma membrane determines permeability of certain molecules. A

In the past‚ kidney functions and diseases have been known as the most important encumbrance1. In 1960 the first patient began treatment at the University of Washington Hospital.2 A study confirmed that polycystic kidney disease is the main cause of kidney failure.3 patient should know about the causes that lead to kidney failure‚ the stages of it‚ symptoms and risk factors to prevent infection or decrease the effect of this disease in the future. Kidney is the most important members

apparatus‚ MD-Macula Densa‚ TGF-tubular glomerular feedback‚ NO-Nitric Oxide‚ NOS-Nitric Oxide Synthase The nephron‚ the functional unit of the kidney‚ is made of 2 parts: the renal corpuscle and the renal tubule. The renal corpuscle is composed of the glomerulus and Bowman’s capsule while the renal tubule extends from the Bowman’s capsule to the collecting duct. The glomerulus is a globular network of capillaries surrounded by Bowman’s capsule. Filtration occurs under pressure through the fenestrations

Maywood‚ Illinois; and 3Department of Electrical and Computer Engineering‚ Illinois Institute of Technology‚ Chicago‚ Illinois ABSTRACT When the kidney is subjected to acute increases in blood pressure (BP)‚ renal blood flow (RBF) and glomerular filtration rate (GFR) are observed to remain relatively constant. Two mechanisms‚ tubuloglomerular feedback (TGF) and the myogenic response‚ are thought to act in concert to achieve a precise moment-by-moment regulation of GFR and distal salt delivery

ACTIVITY ONE- Cell Transport Mechanisms and Permeability: Simulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. Molecular weight affects the rate of diffusion because the bigger the size of the molecule the longer it will take to diffuse. Membrane size is another variable that affects the rate of diffusion because if the membrane’s pores are small it will take molecules longer to diffuse though it than if the pores were larger. Also‚ membrane thickness
