Judging from the trace you generated‚ each inspiration took place over how many seconds? 2 Seconds 3. Each expiration took place over how many seconds? 2 seconds 4. Does the duration of inspiration or expiration vary when you tested/measured the ERV or FVC? Yes Activity 3: Effect of Restricted Air Flow on Respiratory Volumes 1. How does this set of data compare to the

Gas Exchange in Mammals The mammalian respiratory system consists of the nasal cavity‚ pharynx‚ glottis‚ larynx‚ trachea‚ bronchi‚ bronchioles and air sacs (alveoli). The respiratory passages are lined by the presence of cilia and mucus-secreting cells‚ which keep them moist and trap dust‚ dirt and bacteria. The lungs are encased a rib cage. The rib cage is composed of the breastbone or sternum and ribs. At the bottom of the rib cage is a muscular diaphragm. Breathing in mammals. During inhalation

The elevation in her respiratory rate would alter her minute ventalization by raising it. Minute ventilization is determined by timesing respiratory rate by total volume. h. The clinical finding of 90% oxygen saturation level and a Po2 of mmHg would show that the arteries are having too much oxygen‚ since a normal Po2 of a resting person

_______________________________________ Part I—The Initial Physical Examination Scenario Mary and Bill adopted a three-year-old toddler named Sam two weeks ago. Sam is good-natured and very inquisitive. Typically‚ before the finalization of an adoption‚ children are required to undergo a routine examination by a physician. However‚ the required examination is not meant to be a complete health screening‚ and many conditions are not even checked. Therefore‚ Mary and Bill are bringing Sam to Trinity

An explanation of the physiology of two named body systems in relation to energy metabolism in the body. (P4) In this assignment I will be explaining the physiology of two named body systems in relation to energy metabolism in the body‚ the Respiration system and the Digestive system. I will start off by giving a definition of energy metabolism in the body. Metabolism in the body is a collection of chemical reactions that takes place in the body’s cells. Metabolism converts the nutrients in the

ear are connected by ducts in the throat. B. What is the cough reflex? Describe the process that Cari’s respiratory system is using to clear her lungs by coughing. a. Cough reflex is a long-drawn and deep inhalation followed by a complete closure of the glottis‚ which results in a strong exhalation that suddenly pushes the glottis open and sends a blast of air through the upper respiratory passages. This process is clearing her lungs by forcing foreign bodies out of the larynx‚ trachea and epiglottis

Describe the process that Cari’s respiratory system is using to clear her lungs by coughing? A cough reflex has both sensory (afferent) and motor (efferent) components. Pulmonary irritant receptors (cough receptors) in the epithelium of the respiratory tract are sensitive to both mechanical and chemical stimuli. Stimulation of the cough receptors by dust or other foreign particles produces a cough‚ which is necessary to remove the foreign material from the respiratory tract before it reaches the lungs

1. Explain how the respiratory and circulatory systems coordinate the supply and transport of oxygen to the cells and removal of carbon dioxide from the blood. (10 Marks) Paragraph 1: What happens in the respiratory system? Respiratory System: Coordinating the Supply and transport of Oxygen * Oxygen is inhaled through the nose or mouth * Travels down through the Pharynx * Travels down the Larynx * Reaches the lungs and goes through the Bronchi * Through the Bronchioles
