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

HUMAN BODY Our bodies are supported by the skeletal system which is made up of bones‚ ligaments and tendons. The skeletal system works with the muscular system to help the body move. It shapes the body and also protects organs. Inside bones we found the Marrow‚ which is soft‚ fatty tissue that produces red blood cells‚ many white blood cell and other immune system cells. The muscular system consists of about 650 muscles and is responsible for the movement of the

ATP. Glucose is broken down into 2 pyruvate. The pyruvate then travels through the Kreb cycle and produces carbon dioxide. The oxygen travel through the electron transport train and produces water and energy. In order for the body to maintain homeostasis while exercising more oxygen is needed and cellular respiration increases. In return for a greater intake of oxygen‚ more carbon dioxide is produced and exhaled‚ therefore changing the color of the the bromothymol quicker. The results support the

the SNS? What receptors are used by the SNS? The PSNS? What cranial nerves carry parasympathetic fibers? Which cranial nerve is the most important for homeostasis? What is an “en passant” synapse‚ and how does it differ from a neural synapse? Know the three types of effects possible with dual innervation. How does the SNS control homeostasis in the organs that it innervates alone? Know the handout given on the “Summary of the Autonomic Nervous System”. By this‚ I mean know the transmitters

I enjoy researching and learning more about the muscular and reproductive systems it is interesting to learn how they actually work together in our body to help us perform daily tasks in life. I especially enjoy the muscular system‚ I am a physical fit person‚ I enjoy daily exercise and keeping myself healthy and in shape therefore learning more about the muscular system is very interesting. The reproductive system is another wonderful system to study and learn about‚ it is a great part of human

the bodily process of discharging wastes. The Excretory system is responsible for the elimination of wastes produced by homeostasis. Skeletal- The skeletal system gives the body its basic framework‚ providing structure‚ protection‚ and movement. The bones in the body also produce blood cells‚ store important minerals‚ and release hormones. Muscular- some functions of the muscular systems are Movements of body parts‚ Stability and Posture‚ Heat production‚ Circulation‚ Help in Digestion. Respiratory-
