Cassie Ho 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

The fight and flight Response The fight and flight response is our body ’s primitive‚ automatic‚ inborn response that prepares the body to "fight" or "flee" from perceived attack‚ harm or threat to our survival. I decided to test the question how this fight and flight response effects the body. How it effects the cardiovascular system ( pulse rate) ‚ the respiratory system‚ And Watch out for angry red faces‚ cold and clammy skin‚ signs of a dry mouth‚ increased breathing rates and jitteriness

Regulation of the cardiovascular system by examining changes in heart rate Prepared for Dr. Isabelle Lys Lecturer of SBI171 Anatomy &Physiology Charles Darwin University Summer Semester 2012-2013 Introduction Every day the human body is involved in various tasks which can alter a person’s heart rate. Some internal and external factors that contribute to changes in HR are thermo-regulatory changes‚ diurnal changes and sudden postural changes‚ which are among others

YAWNING Physiology‚ Theories and Contagiousness First‚ let’s look at what this bodily motion is: Yawning is an involuntary action that causes us to open our mouths wide and breathe in deeply. We know it’s involuntary because we do it even before we’re born: According to Robert Provine‚ a developmental neuroscientist at the University of Maryland‚ Baltimore County‚ research has shown that 11-week-old fetuses yawn. And while yawning is commonly associated with relaxation and drowsiness‚ your heart

P5. Explaining the Concept of Homeostasis. M2. Probable homeostatic response’s to changes in the internal environment during exercise. The actual word homeostasis means "steady state". Homeostasis describes how the body regulates its process to keep its internal conditions as stable as possible. Homeostasis is necessary because human cells are efficient but very demanding. The phrase homeostasis is a bit confusing; conditions inside our bodies are not constant but are kept within a narrow
