Isotonic

interesting part of this day was learning about trigger point dry needling, also known as intramuscular manual therapy, from the director of physical therapy at TOC, Mr. John Williams. Also, I enjoyed Mr. Keith explaining things like isometric and isotonic muscle contractions. When a young male disclosed his story of hyper extending his knee in a soccer game, I was eager to see the Isokinetic machine aid in his quad strengthening with eccentric loading. The most valuable thing I learned from…

To do this, red blood cells were examined in solutions of three different saline concentrations, 9% salt concentration, 1.8% salt concentration, and 0% salt concentration. A solution of 9% salt is isotonic to red blood cells. A solution of >9% salt is hypertonic to red blood cells. A solution of <9% is hypotonic to red blood cells. In tube one, the blood cells were placed in a tube with the volume of stock 300mM NaCl was 1.00 ml with no water. In tube…

to the fitness principles, in order to keep up or improve muscular endurance, you must use isometric exercises, isotonic exercises, or isokinetic exercises every other day using 30-50% of your max lift. Muscular strength is the amount of force that can be exerted by a single contraction of the muscle. You can maintain or improve muscular strength by using isometric exercises, isotonic exercises, or isokinetic exercises every other day using 60-90% of your max…

Over three days, we tested what would happen to an egg after leaving in various liquids over a 24-hour period. Before letting the egg submerge in vinegar overnight the initial weight of the egg was 66.6 grams. We thought that after leaving the egg in vinegar the shell of the egg would get softer. The independent variable is the vinegar and the dependent variable is the egg. We believed that the egg would be softer; because we saw the vinegar bubble once we put the egg in it. When we came back…

After placing the sucrose tubings into the water for 30 mintues, they each varied with different masses and percent changes. By comparing the percnt changes, the researchrs determined the molarity of ach solution. They believed that solution A was .4M, solution B was 1.0M, solution C was .6M, solution D was .8M, solution E was .2M, and solution F was water. However, after reviewing the classes data, the students realized that solution B was 1.0M and solution D was .8M. The graph showed the error…

changing their shape in order to allow the translocation of solutes. A solution that is hypertonic contains a higher concentration of solutes than water. Conversely, a solution that is hypotonic contains a higher concentration of water than solutes. An isotonic solution is one which has a relatively equal amount of water and solute. This is important in osmosis because the state of the solutions outside and inside the cell determine the movement of the water. For example, if the cell is placed…

While a healthy diet gives plenty of electrolytes, those who participate in intense physical activity may need more. There are several kinds of sports drinks that contain electrolytes available, and each serve a different purpose. Isotonic drinks are average sports drinks, as they have electrolytes and a decent boost of carbohydrates. Hypotonic drinks are for low-sweat activities, as they only provide fluids. Hypertonic drinks are high-intensity, with a large amount of fluids and carbohydrates…

structure has a higher concentration of water on the outside of the membrane than the inside is hypotonic. Hypertonic is when a membrane bound structure has a higher concentration of water on the inside of the membrane than the outside. When something is isotonic the inside of the membrane has the same concentration as the outside of the structure. If water moves from areas of high concentration to low concentration, then an egg in vinegar will be hypotonic because the molecules are moving into…

urinary output of 30-50 mL/hour (Silvestri, 2017). Fluid resuscitation indicated depends on the what the HCP prescribes but common fluid resuscitation formulas for the first 24 hours after a burn injury are as follows: Modified Brooke: 5% albumin in isotonic saline, lactated ringer’s (LR) without dextrose. Amount: 0.5% to 15mL/kg/% TBSA burn. Parkland (Baxter): Crystalloid only (LR). Amount 4 mL/kg/% TBSA burn. Modified Parkland: Crystalloid only (LR). Amount 4 mL//kg/% TBSA burn +15 mL/m2…

Objective: The objective of this lab is to show how diffusion occurs with different types of osmosis. This is done with varying concentrations of solute. Introduction: To fully understand this experiment you should have a solid basis of background information on a few a topics. The cell membrane, for example, is the flexible barrier which surrounds the cell (see Figure 1). This organelle controls what is able to enter and exit the cell, which is known as selective permeability. The…
