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

Regulation of Arterial pressure --long term: excreting variable amounts of sodium and water --short term: secreting vasoactive factors or substances such as rennin 4. Regulation of Acid-Base balance --the only means of eliminating sulfuric acid and phosphoric acid 5. Regulation of Erythrocyte Production

Alterations in Fluids‚ Electrolytes‚ and Acid-Base Balance Composition & Compartment Distribution of Body Fluids ← Body fluids are distributed between the intracellular fluid (ICF) and extracellular fluid (ECF) compartments. The ICF compartment consists of fluid contained within all of the billions of cells in the body. It is the larger of the two compartments‚ containing approximately two thirds of the body water in healthy adults. ← The remaining one third of body water is in

Practical 2: 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

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

Capillaries exchange fluids‚ gasses‚ heat‚ nutrients and wastes to the tissues through diffusion. Capillary walls contain small pores that are selectively permeable allowing only certain molecules to pass in and out. This exchange is controlled by blood pressure through hydrostatic pressure and osmotic pressure. Osmotic pressure is produced by high levels and salts and proteins in the blood. As blood enters the capillary by the arteriole end the blood pressure is higher than the osmotic pressure
