Homeostasis and why it is an important process for survival The environment around us is continually changing and poses difficulties for the body to carry out its internal processes. Homeostasis is the maintenance of a constant internal environment within the body regardless of changes in either external or internal conditions. It allows a certain degree of independence from the environment. Regulating body temperature is one instance where homeostasis occurs (Thermoregulation). Some methods

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”

Period 1 Physiology September 16th 2014 Lab 1: Homeostasis Background Information The conditions in our bodies do not really change at all. Our body temperature has to stay within a certain range in order to function. We maintain these function through a process which is called homeostasis. Homeostasis is the process of maintaining a constant internal environment such as body temperature‚ blood pressure‚ and heart rate. An analogy to help explain homeostasis is a student walking up the down escalator

concept of homeostasis and discuss the probable homeostatic responses to changes in the internal environment during exercise In this assignment the concept of homeostasis will be explained and the probable homeostatic responses to changes in the internal environment during exercise will be discussed. Homeostasis is simply how the body keeps conditions inside the same. It is described as the maintenance of a constant internal environment. Generally‚ the body is in homeostasis when its needs

INTRODUCTION TO PHYSIOLOGY AND HOMEOSTATIS PHYSIOLOGY 1.1 Intro to Physiology Physiology: the study of the functions of living things‚ how the human body works Two approaches explain the events that occur in body -purpose of the body process - mechanism in which the process occurs Physiologists view the body as a machine whose mechanisms of action can explained in terms of cause and effect sequences of physical and chemical processes. Physiology is closely related to anatomy: the
