The Basic Mechanisms of Homeostasis Overview of homeostasis The term homeostasis was first coined by Walter Cannon in 1929 to literally mean ‘steady state’. It describes the dynamic equilibrium by which internal constancy is maintained within set limits by regulation and control. There are many examples of homeostatic control throughout the human body and in other living organisms‚ such as pH‚ pressure‚ and temperature. A concept important to homeostasis is the process of feedback circuits;

Actual Mechanism of Heat Loss during Exercise High heat and humidity reduce body’s ability to lose heat by radiation or convection and evaporation. While exercising‚ the heat production within muscle and it is transfer from the core to the skin. Under appropriate environmental conditions‚ excess body heat dissipates to the environment which regulates the core temperature within a narrow range. During exercise in the heat‚ the heat loss mechanisms compete with the active muscles for more of the

and lactose. Polysaccharides are the long chains of monosaccharide‚ which is called the polymer of carbohydrates. Monosaccharide and disaccharides can be tested by the Benedict’s test‚ as they are reducing sugars. Polysaccharides such as starch and glycogen can be tested by the iodine test. Also‚ carbohydrates are consumed to provide energy to our body and they are useful in metabolism. Therefore‚ it is one of the essential macromolecule that we have to consume. 2. Lipids Lipids are made up of a glycerol

synthesized from carbon‚ oxygen‚ and hydrogen atoms. Some types of carbohydrates consist of a single unit consisting of a few atoms‚ while other carbohydrates consists of thousands of units linked together through chemical bonds. Glucose‚ maltose‚ and glycogen are three carbohydrates that are similar‚ but structurally different. Carbohydrates have the general molecular formula CH2O. Starch and cellulose are the two most common carbohydrates. Both are polymers (hence "polysaccharides"); that is‚ each is

The importance of carbohydrates in living organisms Carbohydrates contain carbon‚ hydrogen and oxygen in the ratio of 1.2.1.. There are many different types of carbohydrate‚ all of which are useful to living organisms. The most important carbohydrate is probable glucose. Glucose is a monosaccharide and is the monomer unit which makes up more complex polysaccharides. Two glucose molecules can be joined in a condensation reaction‚ whereby water is removed‚ for example to produce maltose‚ a disaccharide

Nutrition News The liver is often overlooked when we consider organs integral to exercise‚ but it is an important reservoir of glycogen‚ the body’s stored form of glucose. All sugars‚ including sucrose‚ or table sugar‚ and high-fructose corn syrup‚ which usually consists of almost equal portions of glucose and fructose‚ are converted into glucose‚ and stored as glycogen‚ in the body. Strenuous exercise diminishes or
