Observation of mammalian kidney model and tissue slides. Analyzing kidney filtration using simple filtration system Introduction: Kidney is part of mammalian’s body endocrine system. Every mammals have a pair of kidneys that is located at the middle back of the body and symmetrically beside the spine and below the rib cage. A kidney approximately 0.5% of the organism body weight. Every kidney will receive huge amount of blood to enable them to perform important task. The base unit of kidney is called a nephron

Filtration is commonly the mechanical or physical operation which is used for the separation of solids from fluids (liquids or gases) by interposing a medium through which only the fluid can pass. Oversize solids in the fluid are retained‚ but the separation is not complete; solids will be contaminated with some fluid and filtrate will contain fine particles (depending on the pore size and filter thickness). Filtration is also used to describe some biological processes‚ especially in water treatment and sewage

Primary functions of the kidney: — Maintaining homeostasis through the regulation of fluid and electrolytes and removing wastes through the formation of urine. ž Other important functions: — Regulation of acid-base balance — Control of blood pressure — Renal clearance — Regulation of RBC production — Synthesizing vitamin D to the active form — Secreting prostaglandins — Regulating calcium and phosphorus balance. Nephron ž Each kidney has about 1 million

Name: Affiliated Institution: Course: Date: Water Filtration The methods used in this experiment are simple filtration methods which are used by many water companies worldwide. In this experiment simple lab equipment was used‚ after contaminating water with various contaminants the water was filtered by using cheesecloth‚ sand‚ activated charcoal and alum. The contaminants used in the experiment are the most common and the most hazardous. They include; cleaning detergents

Gel filtration GEL FILTRATION OF PROTIENS Aim: The aim of this experiment is to identify proteins from a complex mixture using the gel filtration technique also known as size exclusion chromatography. This technique is widely used by biochemists when proteins larger than the pores are excluded from the column and the smaller molecules elute last and then collected in test tubes for examination by spectroscopic techniques. The red/brown proteins‚ in particular‚ will be observed closely

For each section‚ read the background and answer any questions before you come to class‚ then in class sketch the specimens listed under each sketch circle. For your sketches‚ include the total magnification under which you viewed the specimen and be very detailed in your sketch. Epithelial Tissue Background Functions of Epithelium

The liver converts excess protein into urea. The kidneys remove unwanted substances such as urea‚ excess water and salt. © Boardworks Ltd 2009 What is urea? Excess amino acids in the body are broken down by the liver‚ producing a waste substance called urea. This process is important because it converts toxic ammonia to urea‚ which is done using carbon dioxide. Once formed‚ urea is transported by the circulatory system to the kidneys. The kidneys filter the blood‚ removing urea and excess water
