Communication‚ Homeostasis & Energy Communication & Homeostasis Outline the need for communication systems within multicellular organisms‚ with reference to the need to respond to changes in the internal and external environment and to co-ordinate the activities of different organs. Organisms need to respond to external stimuli‚ e.g. temperature‚ oxygen concentration and levels of sunlight. These may be over time‚ e.g. winter fur to summer fur‚ or quickly‚ e.g. changing size of pupils. Internal

Understanding the functions of the body systems associated with energy metabolism Energy is used for many of the bodily functions including the ability to ventilate‚ respire‚ move‚ grow and repair. The first law of thermo dynamics states that energy can be transformed from one state to another but cannot be lost. Energy comes in many forms‚ some of these are as follows:- Light Sound Kinetic Heat Chemical In accordance with the First Law an example of how energy can transform is when the sun creates

Structure of main Body Systems: Our body is made up of many different systems which help us to keep alive. Without these systems our organs would not be able to functions at all. There are 10 main systems in our body which include the cardiovascular system‚ the digestive system‚ the renal system‚ the nervous system‚ the reproductive system‚ the immune system‚ the respiratory system‚ the lymphatic system‚ the muscular –skeletal system and lastly the endocrine system. Each of these systems has their

stimulates reabsorption of sodium from the distal cortex. 3. Most diuretics share the same basic mechanism of action: they block sodium and chloride reabsorption. The greatest diuresis is produced by those drugs whose site of action is early in the nephron. 4. Adverse effects caused by diuretics on the extracellular fluid include hypovolemia‚ acid-base imbalance‚ and disturbance of elytrolite levels. 5. The four major categories of diuretic drugs include loop diuretics‚ thiazide
