Cardiovascular system: The circulatory system: The circulatory system is made up of the vessels and the muscles that help and control the flow of the blood around the body. This process is called circulation. The main parts of the system are the heart‚ arteries‚ capillaries and veins. As blood begins to circulate‚ it leaves the heart from the left ventricle and goes into the aorta. The aorta is the largest artery in the body. The blood leaving the aorta is full of oxygen. This is important for

How Exercise Helps Reduce Stress Published: 26th December 2009 Views: 27621 We have heard it so many times before that there are many benefits to exercise especially when used to lower stress. If everyone knows that exercise is important then why is stress‚ disease‚ and fatigue so prevalent in today’s society? The answer is simple. We know what to do we just aren’t doing it. Experts agree that one best way to manage stress is through exercise. Exercise has been proven to relax the body

movement of the molecules continues even at the equilibrium. Osmosis: Is the diffusion of water across a membrane. Hypertonic: Water diffuses out of the cell‚ causing it shrink. Hypotonic: Water diffuses into the cell‚ causing it to swell. Isotonic: Water diffuses into and out of the cell at equal rate‚ causing the cell to stay the same size. 4 Egg #1 Egg in the vinegar solution Problem: What will happen if I put an egg in vinegar?

that time are still in motion‚ but the amount of molecules moving in one direction equals to the amount of molecules moving in the other direction. There are three types of solutions to diffusion: isotonic‚ hypertonic‚ or hypotonic. When the solutions have the same concentration of solutes‚ they are isotonic. When the solutions differ in their solute concentration‚ the solution with more solute is hypertonic to the other solution. The solution that has less solute is hypotonic

This indicates that solution X is isotonic because the concentrations are similar‚ resulting in no difference in appearance. Solution Y is hypertonic because it shrank the membrane in plasmolysis‚ which forced all of the chloroplasts to the center of the cell. The cell possessed a higher

Introduction: I know prior to doing this experiment that iodine mixed with starch creates a dark color and that most objects‚ organic and inorganic‚ naturally experience isotonic reactions. Hypothesis: I think that the potato will absorb more starch than the sweet potato and they will both absorb relatively similar amounts of water. Procedure: Variables: Controlled- water and size of potatoes. Manipulated variables- potatoes

Today there is an implausible range of physical activities on offer‚ from the commercially motivated activities that are enjoyable and challenging‚ such as indoor rock climbing‚ to the more traditional exercise types. The challenge for the individual is to find an exercise type that meets their fitness needs and that is enjoyable. Many individual fitness activities are available‚ some which require specific knowledge and skills. Raised awareness of health has led to the stimulation of many fitness
