During this experiment‚ three different volumes were measured in order to give a better understanding of the capability and durability of your respiratory system. In order to determine the results there were two main processes that had to be preformed. These processes include inhalation and exhalation. Inhalation‚ or inspiration occurs when air is moving into your lungs. The second processes‚ exhalation‚ or expiration occurs when air is moving out of your lungs (Gutiereez‚ 2014). Even though

What is Exercise Physiology? Exercise physiology is a scientific discipline that focuses on how an organism responds to exercise. Exercise represents one of the greatest stresses that an organism can encounter. Therefore exercise represents an outstanding model for studying human and animal physiology. Most people are familiar with the study of exercise physiology as it relates to sport performance. However‚ in the last several decades it has become apparent that the study of exercise

again. So I decided to write it out. Here is my own journey in a seventh grade student that inhales that you will never experience again. It all started when a seventh grade student inhaled deeply in a Science Classroom. They were studying the Respiratory System in a human body. The teacher said to inhale and exhale deeply. So the student inhales and I decided to enter his nose with other molecules of oxygen to have a unique experience. After being smooched to enter his narrow nose‚ I saw several

investigate the effects of exercise on lung volume. Spirometer Spirometry is the most basic and frequently performed test of pulmonary (lung) function. A device called a spirometer is used to measure how much air the lungs can hold and how well the respiratory system is able to move air into and out of the lungs. A spirometry test is done with a spirometer‚ which consists of a mouthpiece and disposable tubing connected to a machine that records the results and displays them on a graph. To perform spirometry

Respiration is the process that takes place in every living cell to make energy available to the body. Energy is vital for us to carry out many life processes such as movement and so respiration in essential to life. During respiration glucose and oxygen are used in a reaction that produces energy and gives out carbon dioxide and water as waste products. Glucose is obtained by digestion of food and oxygen is taken from the air during a process called breathing or ventilation. Pulmonary Ventilation

The regions where the pain is coming from are where the sinuses are located. If the sinuses remain blocked for a long time‚ a secondary infection may result. This secondary infection is caused by bacteria‚ which are normally present within the respiratory tract. These bacteria multiply and cause a secondary infection in the paranasal

Spirometry is a diagnostic pulmonary function test. Relatively easy to perform‚ for both the patient and the clinician‚ Spirometry testing is noninvasive. The spirometry tests measure lung volumes. There are many reasons spirometry testing is done. Most common would be to assess lung function in disease process‚ but studies are also done in exercise testing for lung capacity and expenditure of oxygen. Speech Language Pathologists are also concerned with Spirometry testing. The lungs are the power

pharyns spread into her sinuses? The infection in Cari’s nasal passages and pharynx was able to spread into her sinuses due to the sinuses being a drainage area for the nasal passages. What is the cough reflex? Describe the process that Cari’s respiratory system is using to clear her lungs by coughing. The cough reflex is used to clear sputum and irritants that are in the nasal passages and pharynx. There are cilia in her trachea that is moving mucus up from the lungs. When the mucus becomes or abundant
