Glomerular Filtration Pressure

The lymphatic system supports homeostasis by helping to maintain fluid balance. It collects excess fluid and particulate matter. It deposits them in the blood stream through the

The glucose diffused through the 200 MCWO It increased the filtration rate because the blood pressure increased, but the concentration of solutes did not because the pore size did not increase.

Hypothesis: 1) If the solution contains only sucrose then the osmotic pressure will increase substantially. This would represent a hypotonic solution because more water molecules are entering the cell meaning the solution contains no invertase. If the osmotic pressure has a slight increase than the solution contains sucrose and invertase due to the rate of the sucrose being broken down, however the cell will overtime begin to shrink. If the osmotic pressure remains close to the same than the solution contains no sucrose, containing only water and invertase. We predicted that because the height of the fluid in the osmometer tubing was increasing only a little bit our blue solution was hypertonic and contained invertase and sucrose. The invertase was able to break down sucrose into glucose and fructose which were small enough to be able to leave the cell membrane. This would reflect a hypertonic solution. We predicted this would cause the cell to shrink in size and the height of the fluid would never increase.

LAB REPORT I VARIABLES AFFECTING HUMAN ARTERIAL PRESSURE AND PULSE RATE 2014 FA-BIOL-204 (HUMAN ANATOMY AND PHYSIOLOGY-II)-552 LAB NABIN KC TIM SPARKLIN PATRICIA KATHLEEN MORGAN OCT 15 2014 INTRODUCTION: The blood circulates around the body. The heart contract and relax, this mechanism of heart makes the blood to flow in the arteries to the body from heart and come back from body to heart through veins. The arteries carry oxygenated blood or oxygen rich blood and the veins carry deoxygenated blood or oxygen poor blood. This flow creates the pressure on the arterial wall and the pressure that is exerted on the arterial wall is known as blood pressure. Blood pressure is expressed by the

Peak expiratory flow rate (PEFR) is a measure of how much a person can breathe out in a single large breath. PEFR is used as a clinical tool to test the functionality of a patient’s lung, the severity of asthma or other respiratory illness symptoms and the best course of treatment for the patient. The PEFR reading will be lower when a person’s airways are constricted and should be at its highest when the patient is at full health. The PEFR is measured using a small handheld device known as a peak flow meter.

With this information the diagnosis of Chronic renal (kidney)(stress) (Gould, B. E. , pg 196-197, 2011) If George was in the second stage of chronic renal failure, what percent of his nephrons have been lost? What changes will be seen in the GFR; urination; and percent of nephrons lost when George reaches end-stage renal failure?

Based on Goodman and Fuller (2015), it was estimated that the annual population in the United States with (CHF) congestive heart failure is about five hundred fifty thousand, and approximately five million male and female elderly individual (65 years old and above) is the leading cause of hospital

1. Explain the pathophysiology of acute renal failure. Include prerenal, intrarenal, and postrenal causes. Both of our kidneys functions to filter and excrete waste products and toxins by regulating fluids, electrolytes, and acid based balance. If the Renal blood flow is altered then the glomerular filtration rate will be altered as well. A decrease in systemic pressure stimulates the sympathetic nervous system to constrict the renal artery and decreases filtration and secretion in the kidney. In addition, a tubular obstruction can lead to the reduction of Glomerular filtration rate. An elevated intracellular calcium level due to tubular damage may alter cellular level that increases tubuloglomerular feedback and diminishes GFR. This may be prerenal, intrarenal, or postrenal. The prerenal will result from any condition outside of the kidney that disables the blood to flow to the renal vasculature causing a decrease in perfusion in the glomerulus leading to oliguria. However, both of the kidneys can still return to its full normal function on this stage. Second of the three is intrarenal, where anything can cause a direct damage to both of the kidneys such as infections, toxins, reduce blood supply, hypertension, diabetes, and even glomerulonephritis. The most common intrarenal condition is Acute Tubular Necrosis, where the epithelial layer of the nephrons are damaged causing a change in the concentration of urine, waste filtration, and an imbalance in electrolytes and acid

#45 1) Filtration: blood enters the afferent arteriole and flows into the glomerulus where filterable blood components such as water and nitrogenous waste will move toward the inside of the glomerulus, and nonfilterable components such as cells will exit through the efferent arteriole. The filterable components accumulate in the glomerulus to form the glomerular filtrate.

The function of Residual Volume 2. FVC stands for Forced Vital Capacity which measures how much gas is expired when a deep breath is taken and then forcefully exhaled as quickly as possible. FEV1 stands for Forced Expiratory Volume which determines how much air is expired or breathed outwards during specific intervals of the forced vital capacity test. The physiological significance of the FEV1 / FVC ratio can determine the effectiveness of a persons lungs during the turn over of its total volume in one second. This is important because this ratio can help distinguish between obstructive and restrictive disorders meaning lung expansion can be determined to be limited or lungs can be hyperinflating depending on the disorder.

Table 2. EC50 values for the effect of acetylcholine and nitroprusside. EC50 in nM | Shearing forces acting on the vascular endothelium generated by blood flow causes a release of calcium and subsequent cNOS (cyclic nitric oxide synthase) activation. Therefore, increases in blood flow stimulate NO formation (flow-dependent NO formation). Nitric oxide then causes independent vasodilation by inhibiting vasoconstrictor influences of phenylephrine and alters its potency and contractile effect. (Richard E. Klabunde. 2010)

Diabetic Ketoacidosis Background Diabetic Ketoacidosis (DKA) is an acute complication of uncontrolled glucose levels characterized by reduced levels of insulin and presence of ketones. It is a medical emergency and results can be detrimental if left untreated. DKA is commonly seen in patients with type 1 diabetes mellitus (type 1

The main purpose of this lab was to study the capillary pressure (Pc) in eight sandstone core samples in order to obtain saturation values and the height above the free water contact in the reservoir rocks. In general, capillary pressure can be defined as the difference in pressure between two immiscible fluid phases (usually oil and water) that occupy the same pores. It is basically generated by the interfacial tension between two different phases. It is considered to be one of the important factors that control fluid distribution in reservoir rocks. Moreover, capillary pressure can be the key to determine the relationship between important rock properties such as porosity, permeability, and water saturation above oil-water contact in reservoirs.

Glomerular Filtration Activity 1:  Effect of Arteriole Diameter on Glomerular Filtration 1.   Compare this data with your baseline data.  How did increasing the afferent arteriole radius affect glomerular filtration rate? >>Increasing the afferent arteriole radius pushed the glomerular pressure, the glomerular filtration rate, and the volume of urine to be higher than the
