Body fluids are maintained at a constant level by several homeostatic mechanisms: Osmosis- is the diffusion of water through a selectively permeable membrane known as a plasma membrane. Water is highly polar it is repelled by the lipid core (nonpolar) of the plasma membrane but can easily pass through the aquaporins created by the proteins in the membrane‚ so osmosis is happening all the time as water moves into and out of cells. Diffusion- Is where ions move away from an area where they are

Think back to the key question. List two different fluids. How are their flow rates different? A3. Water and syrup flow rates are different because water has a high viscosity and syrup has a low viscosity rate. 7.3 Comparing Fluids (pg 157) Answer the questions below Q1. Andre and Kim have two fluids. Andre’s fluid flows much more easily than kim’s fluid.. (a) Which fluid has a faster flow rate? Andre’s (b) which fluid is more viscous? Kim’s Q2. Identify if each is

The history of the intravenous therapy is less than a century old. Yet‚ it is well known that medication could be injected directly into the vein as early as the 1600’s‚ because of the lack of scientific methods‚ original attempts to deliver IV fluids and drugs met with little success. Two world wars brought in the era of modern IV therapy. However‚ the greatest advance in drugs‚ equipment‚ and procedures has occurred in the past 25 years. The first intravenous injections were experimented with in

What of Embalming Fluids? Our earliest knowledge of when/where embalming first occurred was around over 5‚000 years ago in Egypt. Then‚ embalming was used for religious purposes and to keep the body from decaying until Christianity began to dominate; Embalming purposes were turned into being used for body preservation for dissection and studying. In the U.S though‚ there originally wasn’t any true way of embalming for funeral reasons. Originally we just used ice in order

Class: DME2 Title: Flow Measurement Date: 11/02/2013 Lecturer: Mr Higgins Summary: In this experiment many different meters were used to measure fluid flow rate; the orifice plate‚ the venture meter‚ the rota meter and the weigh tank. Each meter works by its ability to alter a certain physical property of the flowing fluid and then allows this alteration to be measured. The measured alterations are linked directly to the flow rate and these measurements are subbed in to adjusted equations
