1. Briefly explain how does the body maintain homeostasis? Homeostasis is a existence and maintenance of a relatively constant internal environment. Homeostasis is maintain by negative and positive feedback mechanism. Most homeostatic control mechanisms are negative feedback mechanisms. In these system‚ the output shut off the original stimulus or reduce its intensity. These mechanisms cause the variable to change in a direction opposite to that of the initial change‚ returning it to its “ideal”

The endocrine system works with the nervous system to maintain homeostasis. The endocrine system secretes hormones in the human body‚ which are produced in endocrine glands and are released into the bloodstream to travel to the its specific target cell‚ tissue‚ or organ. Exocrine glands produce chemicals that are discharged into the surroundings. Hormones can either produce short-lived responses or long-term responses. An example of a short-lived response is when adrenaline (epinephrine)causes the

The human body has to be controlled from advanced systems internally of which connect in order to function effectively. There are ten main systems within the body of which all perform various activities and all interrelate with at least one other system; the nervous system. The most complex of all body systems‚ the nervous system controls all functions within the body. The main function of the respiratory system is to inhale oxygen and exhale the waste product carbon dioxide. Oxygen is breathed

Analyse how the cardiovascular and the digestive system interrelate to perform energy metabolism. Energy is used up all the time for body processes. Energy starts at conception and continues to carry on until you die. The amount of energy you need depends upon your age‚ sex and your level of activity. Food provides the energy we use; our foods bring us the vital energy that our body is burning throughout the day. Body growth‚ development and functioning are some of the vital and fundamental aspects

How to Maintain A Computer System Start a notebook that includes information on your system. This notebook should be a single source of information about your entire system‚ both hardware and software. Each time you make a change to your system‚ adding or removing hardware or software‚ record the change. Always include the serial numbers of all equipment‚ vendor support numbers‚ and print outs for key system files. Secondly periodically review disk directories and delete unneeded files. Files

Homeostasis is the body’s ability to maintain a constant balance between the internal environment and external environment at a constant rate‚ despite changes which may affect our external environment such as body temperature and the amount of water in our bodies. By keeping this internal balance it allows our bodies to function efficiently. The negative feedback loop is produced when changes to our internal environment changes from its normal range. In this instance the brain and the nervous system

Homeostasis is defined as the adjustments a body makes to maintain an environment conducive to life. All of the organ systems in the human body must maintain a steady internal environment for the body to function properly. The factors that need to be controlled are water and salt content‚ PH balance‚ oxygen‚ sugar‚ protein‚ body temperature‚ and blood and glucose concentration. The basic principle of homeostasis is when there is an abnormal internal condition‚ it will be detected and a variation

Oxygen is required for cellular functions such as cell respiration. This is so the body’s organs and cells can work at fully; it is done by releasing chemical energy with in stored foods. The air breathed in and held in the lungs is transferred to the blood. The blood is circulated by
