WHAT DOES THE BIOLOGICAL PERSPECTIVE CONTRIBUTE TO THE UNDERSTANDING OF PSYCHOLOGY. ILLUSTRATE YOUR ANSWER WITH EXAMPLES FROM CHAPTER 4 IN BOOK 1. (ENCLOSED, OR ATTATCHED) THIS WORK WILL HAVE TO BE DONE ON THIS CHAPTER.

Biology and Psychology : Where is the Linkage

Biology and psychology are meaningfully and intricately linked . In psychology , human behavior can be explained by carefully studying life itself , including the components and structures affecting the of a human being . Moreover , environment plays a major role affecting the reaction and responses of both simple and complex organisms . The two fields are likewise connected through heart systems and circulation . An individual in a negative psychological state increases the release of fatty substances blocking the blood vessels the release of these fatty substances is decreased particularly

if the individual is in a positive psychological state . Biology and psychology are integrated theless they still retain principles distinct to each realm

Both simple and complex organisms are made up of cells . The most complex organisms - humans , are made up of several types of cells each having their specific function . Among the cells making up the human body neurons are considered to be the most important , since these function for control and communication . They act as the controller of different cells , regulating each function and ensuring that every process is in its proper rhythm . Organisms with neurons (nervous system -neurons in cluster , brain and other organs ) are capable of performing tasks of utmost complexity

Evolution has taken place resulting to changes of the physical and behavioral characteristics of an organism for survival and reproduction purposes . Mechanisms and strategies are learned to equip organisms with the skills necessary for survival in their particular habitat . Human beings need food and water for existence they feel hunger and thirst and as a response , one must eat and drink . The behavior of an individual is also affected by external factors . For instance , if food and water are not available , how can he feed himself ? With this , new behavior from an individual may be expected as a way of adapting to these external variables . Temperature and body fluid level affect behavior . If these factors deviated from their normal range , the body exhibits specific reactions to normalize this and reach equilibrium . Shivering is a body 's response at cold temperatures it is the body 's response to generate heat against cold temperature . Thirst , sweating , and urine production are regulated by the body fluids . Psychological states are regulated and corrected if these deviate from normal , to maintain balance or homeostasis

Both internal and external factors are taken as an aggregate in determining behavior . The brain takes charge of processing the information , ending up with results aimed to regain or maintain the normal state . The brain regulates the responses created by both internal and external variable and the responses and behavior observed from an individual has solid scientific basis . An internal or external factor triggers the organism to react or behave in that manner . For each action done , a scientific or biological explanation may be put forth . If an organism feels danger for himself , it would be instinctive or automatic for him to protect himself from his predators
