oxidation as soon as it is ingested. The liver metabolizes large amounts of alcohol and small amounts are eliminated in the feces and nursing release some alcohol in their milk. The initial step is the conversion of alcohol to acetaldehyde by the enzyme ADH. The acetaldehyde is converted by another liver enzyme to an active acetate that is broken down into carbon dioxide and water. The metabolism of alcohol results in significant changes in the ratio of important chemicals within the liver cells. The average

CHAPTER I THE PROBLEM AND ITS BACKGROUND Introduction Cigarette smoking has been prone to Filipinos due to the influences of the foreign culture. Alcoholic drinks are believed to ease the problems of the Filipino men and even women. As time goes by‚ younger and younger ages of Filipinos are engaging themselves to it. Filipinos are known for close family ties and our peer groups or “barkada”. “Among the high school students‚ majority of them are engaged to alcohol drinks at young age. Early in

Feedback Mechanisms How do organisms regulate complex systems through chemical interactions? Why? The heating system of a house works to keep the temperature constant. If the house gets too cold‚ then the heat automatically turns on to warm the house. The heat stops when the preset temperature is reached. This is an example of a feedback mechanism. Organisms use many feedback mechanisms to either maintain or amplify important chemical systems. This could happen at a molecular level to coordinate

CHAPTER 10 EXERCISE IN HOT AND COLD ENVIRONMENTS: THERMOREGULATION Learning Objectives Find out how the body gets rid of excess body heat to maintain homeostasis at rest and during exercise. Discover how the body adapts to exercise in a hot environment. Learn why humidity‚ wind‚ and cloud cover are important factors when exercising in the heat. Differentiate heat cramps from heat exhaustion from heat stroke. (continued) 1 Learning Objectives Learn how the body minimizes excessive

Blood Water Homeostasis or Osmoregulation Osmoregulation is the process by which the body regulated the osmotic pressure of any organism’s fluids in order to keep the homeostasis of the organisms’ water level constant. Therefore osmoregulation is used to keep the bodily fluid from being too diluted or too concentrated. An osmotic pressure is used to measure the ability of water to move from one solution to another solution through osmosis. Osmotic pressure refers to tendency for a liquid solution

Homeostasis Homeostasis refers to the ability of the body or a cell to seek and maintain a condition of equilibrium or stability within its internal environment when dealing with external changes. It is involved in the maintenance of the constant internal environment which includes the function of kidney‚ liver‚ skin‚ etc. In humans‚ homeostasis happens when the body regulates body temperature in an effort to maintain an internal temperature around 98.6 degrees Fahrenheit. For example‚ we sweat to
