COPD is an umbrella term that refers to a group of lung diseases that block airflow during exhalation‚ which makes it increasingly difficult to breath. Emphysema and chronic asthmatic bronchitis are the two main conditions that make up COPD. In all cases that damage to the airways eventually interferes with the exchange of the oxygen and carbon dioxide in the lungs (mayo). COPD is the third leading cause of death in the United States. It is estimated that there is currently 16 million people in the

The systems cannot work by themselves as they both provide the materials needed throughout the body. They supply energy to all the cells throughout the body. The respiratory system and digestive

I found Joseph T.J. Smith life story very neat. I’m very proud that it was very inspirational and I’m also glad that he was able to come share it with us. Throughout the many downfalls better will always come. TJ smith story was most people of our motivation that took it to heart. When telling us about his first job experience made me think about if I should get a job or not. When having his first job as being cashier at the supermarket. It was out of nowhere how he got the job. The manager of the

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 study

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
