in order for an IV to be isotonic to plasma, its tonicity must be within the range 0.20 to 0.28 OsM  4.0 to 5.0 OsM 0.34 to 0.40 OsM 0.28 to 0.34 OsM

Fill in the missing values in the table. Assume that the temperature is 37°C  Round to the nearest 0.1

A cell with a total of 0.3 osmol/L is placed into a solution with a total of 0.2 osmol/L.  It is assumed that the osmotic particles cannot pass through the cell membrane. Answer the following true or false questions. 1. All particles will diffuse down a concentration gradient, that is, move from a high concentration into a lower concentration  2. Diffusion down a gradient happens because particles are constantly moving (Kinetic Theory) 3. When solvent particles move down a gradient through a membrane it is called osmosis

The effect of pressure on flow rate Set-up: For investigating the effect of pressure (height of a column of liquid), a 50-mL burette was used with a small length of rubber tubing fixed to the bottom on which a clamp could be fitted to start/stop the flow of water (Figure 1). Effluent was collected in a beaker and mean flow rate was calculated (mL/s), and a stopwatch was used to measure how long it took for 5 mL of liquid to flow out. For the subsequent sections of the practical, a 25-mL burette was used, and the top was connected via rubber tubing to a 5-liter reservoir placed on the shelving above the bench. The tubing at the base was connected to the different flow modules that comprised the different configurations of tubes to be tested. Interpret the graph. What does this relate to in the cardiovascular system, and is it something that can change? How? What would be the implications for our ability to control blood flow to different tissues, if this were the only control mechanism…
