membrane is selectively permeable‚ so only necessary materials are let into the cell and wastes are left out.[8] The word ’osmosis’ is particular to the diffusion of water molecules into the cell. 2.) What is Osmotic Pressure? Osmotic pressure is the hydrostatic pressure produced by a solution in a space divided by a semipermeable membrane due to a differential in the concentrations of solute. Osmotic potential is the opposite of water potential with the former meaning the degree to

Does Exercise Affect Blood Pressure and Heart Rate? Hypothesis If an individual is put through vigorous exercises‚ then his/her blood pressure and heart rate will be affected because of the increase in activity.

Objective: Use cuff manometry to measure arterial blood pressure. Questions: 1. My blood pressure for this lab was 123/78. These numbers are normal‚ compared to the normal rating of 120/80. My pulse pressure was 45 (SP – DP). My mean arterial pressure was 93 (DP + 1/3 (SP – DP). 2. Mean arterial blood pressure is determined by cardiac output and total vascular resistance. The mathematical equation for mean arterial blood pressure is equal to cardiac output x total vascular resistance. The amount
