22 Respiratory System The Respiratory System Respiratory System Consists of the respiratory and conducting zones Respiratory zone: Site of gas exchange Consists of bronchioles‚ alveolar ducts‚ and alveoli Respiratory System Conducting zone: Conduits for air to reach the sites of gas exchange Includes all other respiratory structures (e.g.‚ nose‚ nasal cavity‚ pharynx‚ trachea) Respiratory muscles – diaphragm and other muscles that promote ventilation Major Functions of the Respiratory

Respiratory System Respiration: The primary function of the respiratory system is to obtain oxygen gas for cell metabolism and remove carbon dioxide waste. Describe each of the following general processes of respiration. Ventilation- air is moved into and out of the lungs so the gases there are continuously changed and refreshed external respiration- oxygen diffuses from the lungs to the blood‚ and carbon dioxide diffuses from the blood to the lungs gas transport- oxygen is transported

Chapter 11 ARDS INTRODUCTION Acute respiratory distress syndrome (ARDS) - lung inflammation seen at the level of the alveolar capillary membrane with increased vascular permeability. ARDS results in: bilateral pulmonary edema and atelectasis despite no evidence of left heart failure (e.g.‚ normal pulmonary capillary wedge pressure (PCWP). ARDS is present when the ALI results in such severe hypoxia that at the PaO2/FIO2 ratio is 200 mm Hg or less. Approximately 10% to 15% of intensive care

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

Alterations in Respiratory Function 1. Define and use the key terms as listed in the assigned readings 2. Using the four adaptive modes of Roy’s Adaptation Model (RAM)‚ recognize human adaptive responses to behavior or stimuli that affect respiratory function. 3. Identify differences‚ which affect the respiratory system in young‚ middle‚ and older adults. 4. Identify signs and symptoms of acute respiratory distress from impaired gas exchange. 5. Incorporate assessment of respiratory risk factors

Fill in the missing organs of the respiratory system: Nose and mouth (air enters) nasal cavity Larynx (both air and food move through) trachea Bronchi (large tubes leading to both lungs) lungs. 2. Each lung is surrounded by two layers of serous membrane known as pleurae. These are: Visceral pleura; covers the surface of the lung Parietal pleura; lines the thoracic wall The space in between is called the

Respiratory Mechanics 1 Note there is an error in your lab book! The starting radius for the flow tube diameter should be 5mm in each experiment and NOT 6mm.Use your computer link to ADAm for this part of this week’s lab. You are also responsible for the PowerPhys lab report. Measuring Normal Respiratory Volumes 1) Calculate the minute respiratory volume using the tidal volume and breaths per minute (pump rate). 2) Define the following terms: a. Respiration- The act of breathing

Respiratory System Mechanics Simulation Lab Activity 1: MRV __7500__ ml/min =500 tv x 15bmp Does expiratory reserve volume include tidal volume? Explain. Expiratory reserve volume (ERV) does not include tidal volume. Expiratory reserve volume is the amount of air that can be expelled after a normal tidal exhalation. This means that tidal volume is not included in the ERV measurement. Activity 2: FEV1‚ as % of VC Radius FEV1 Vital Capacity FEV1% 5.00 3541 4791 73.90 4.50
