PPT-Trachea

Beneath the submucosa 1620 Cshaped hyaline cartilages that keep the lumen permanently open Cartilages form an incomplete ring around the trachea Open on the posterior aspect where a thick layer of smooth muscle fibers . lung disease. 4.1 Structure of the human gas-exchange system. Remember these guys?. Breathing - brainpop.swf. Learning objectives. Student should understand the following:. The gross structure and function of the human gas exchange system limited to the alveoli, bronchioles, bronchi, trachea and lungs.. LARYNGOTRACHEOBRONCHITIS. Prepared by: Emmylou R. . Mari. Definition:. Triggered mostly by viral infection of the upper airway. Affects the lower laryngeal area, trachea, and occasionally the bronchi (. The respiratory system uses many parts for breathing in oxygen . and releasing . carbon dioxide. .. These include the nose, the trachea, and the lungs. . First, air . enters through . the nose and mouth. Practical Exam Practice. Identify the Structure and Function. Diaphragm. The diaphragm is a muscle that lies below the lungs that separates the thoracic cavity from the abdominal cavity and functions to force air into and out of the lungs, along with the intercostal muscles. . . Biology Department . 1. 2. RESPIRATORY ORGANS . The respiratory system . starts. with a pair of . external nostrils . The . nostrils open into . nasal passage . that is situated above the . buccal cavity. Transports air into the lungs and facilitates the diffusion of oxygen into the blood stream. Receives carbon dioxide from the blood and exhales it. Organs of the Respiratory system. Slide 13.1. Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings. R. espiration?. Cellular Respiration. . - . the process by which cells get energy from the breakdown of glucose in the presence of oxygen. Takes place in the mitochondria. External Respiration. . - The process of gas exchange between the lungs and the environment. . NOTE A Each airsac is covered with tiny blood vessels CAPILLARIES Oxygen moves from air sacs into capillaries Carbon dioxide moves in the opposite direction Red blood cells transport these gases to an Key terms. Having to do with the sinus. Sinus . Air-filled cavity within a bone that is lined with mucous membrane that makes mucus. Functions of the sinuses. Make the bones of the skull lighter. Help produce sound by giving resonance to the voice. Trachea. Rhinotomy. -Incision into nasal cavity. Tracheostomy. -Creation of temporary to permanent opening into the trachea.. Vocal . cordectomy. - . )Debarking or Devocalization)-Resection of vocal cord.. Components. Tubes that filter incoming air. Air transported to alveoli (gas exchange). respiration. Respiration: process of gas exchange between atmosphere and body cells. Consists of. Ventilation. G. 1 Respiratory System Divisions • Upper Airway – Nose, pharynx, larynx and associated structures • Lower Airway – trachea, bronchi, lungs 3 Midsagittal section through the upper airway 4 What is Tracheal Cancer? The trachea, also known as the windpipe, is a very complex organ that connects the voice box (larynx ) to the lungs. The cells lining the trachea help protect the lungs Asst Prof. Dept of Rachana Shareera. SMVVS RKM AMC. VIJAYAPUR. . INTRODUCTION. Trachea (In latin air vessel) is a wide tube Lying more or less in midline, in the lower part of neck and in the superior mediastinum.
