of Group Members: Date: Introduction: In this lab‚ you will be examining many characteristics of a rat’s anatomy. Dissections help researchers get a 3-dimensional picture of how the systems of a body work together. Now you’ll have the opportunity to see how the respiratory‚ digestive and circulatory system are arranged spatially. The Classification of the Rat (Rattus norvegicus): Kingdom: Animalia Phylum: Chordata Subphylum: Vertebrata Class: Mammalia Order: Rodentia

OF THE RESPIRATORY SYSTEM The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe‚ we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system’s means of getting oxygen to the blood. Respiration is achieved through the mouth‚ nose‚ trachea‚ lungs‚ and diaphragm. Oxygen enters the respiratory system through

The Function and Mechanics of the Digestive System SCI/241 The Function and Mechanics of the Digestive System My 4 year old daughter asked me‚ “Mommy‚ how does food go to my stomach?” It is really weird the questions children ask but I had to explain. In this paper I will explain the function and mechanics of the digestive system. The body ’s method of taking the food we eat and breaking it down to obtain vital nutrients that will allow us to live and be healthy is digestion. According

The neurons of the heart are not directly controlled by the human body’s central or peripheral nervous systems. Even without stimulation of the nerves‚ the heart will continue to beat at a steady rate (Wibbels & Vickery 2007). That

The respiratory system carries out gas exchange; major organs in the system include: the nose‚ pharynx‚ larynx‚ trachea‚ bronchi‚ and lungs. The major function of the respiratory system is to supply the body with oxygen and dispose of carbon dioxide. In order for this to happen‚ at least four events called respiration must occur. The first is the pulmonary ventilation. The air must move in and out of the lungs so that the gases in the alveoli are continuously refreshed. This process is better known

rib cage moves down and in diaphragm relaxes. The lungs are the main part of the respiratory system. The respiration system produces energy from taking oxygen and produces carbon dioxide which is takes place in the cells. The oxygen goes to the mitochondria inside the cell where it combines with sugar to create energy and produce carbon dioxide and water. The respiratory system connects to circulatory the system because blood goes to the lungs and to picks up oxygen and releases carbon dioxide
