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

Outcome 1- Understand anatomy and physiology in relation to moving and positioning individuals 1. The anatomy and physiology are important in relation to the correct moving and positioning of individuals as the anatomy is the physical structure of the body and the physiology is the functions of the body. When working with people with limited or reduced mobility‚ care workers must be aware that client’s movements may be slower and more difficult‚ with muscles becoming weak and floppy. Therefore

BSC2085 Anatomy-Physiology 1 Exam 2 Study Guide‚ Chapters 5 & 6 There are only four primary tissue types found in adult organs; epithelial‚ connective‚ nervous‚ and muscular tissue. Epithelial tissue lines body cavities‚ covers the body surface‚ and forms the lining of many organs. Connective tissue serves in most cases to bind organs to each other. Nervous tissue and muscular tissue are considered excitable tissues because they are very sensitive to outside stimuli. A simple epithelium consists

SKIN I. INTRODUCTION Skin‚ outer body covering of an animal. The term skin is commonly used to describe the body covering of any animal but technically refers only to the body covering of vertebrates (animals that have a backbone). The skin has the same basic structure in all vertebrates‚ including fish‚ reptiles‚ birds‚ and humans and other mammals. This article focuses primarily on human skin. The skin is essential to a person’s survival. It forms a barrier that helps prevent harmful microorganisms

Name and describe the attributes of the two categories into which all organisms can be divided based on how they obtain nutrition. All organisms can be divided into autothrops‚ which produce their own food‚ and heterothrops‚ which need to get their food from somewhere else. 3.
