Functionally, the respiratory system can be divided into a conducting zone and a respiratory zone. Respiratory system (Systema respiratorum) The respiratory system, also called the pulmonary system, consists of several organs that function as a whole to oxygenate the body through the process of respiration (breathing).This process involves inhaling air and conducting it to the lungs where gas exchange occurs, in which oxygen is extracted from the air, and carbon dioxide expelled from the … The lower respiratory tract is located almost entirely within the thorax and is composed of the trachea, all segments of the bronchial tree, and the lungs. These structures pull in air from the upper respiratory system, absorb the oxygen, and release carbon dioxide in exchange. The upper respiratory tract comprises the nasopharyngeal and laryngeal tissues. Secondary (labor) Bronchi. The conducting tract consists of airways that transport gases into and out of the … Label the anatomy of the lower respiratory system. The lower airways or lower respiratory tract includes the portion of the larynx below the vocal folds, trachea, bronchi and bronchioles. The trachea is about 4. Start studying Figure 36.3 Structures of the lower respiratory tract. Hairlike structures called cilia line the mucous membrane and move the particles trapped in the mucus out of the nose. Label the histology of the trachea. The lungs can be included in the lower respiratory tract or as separate entity and include the respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli. Anatomy of the exercise36 Respiratory System Review Sheet 36 283 Upper and Lower Respiratory System Structures 1. Epiglottis. 16 13 17 15. Other structures, namely the thoracic cage (or rib cage) and the diaphragm, protect and support these functions. Start studying Respiratory System (Structures of the Respiratory System). Lower respiratory tract. Deep in the lungs, each bronchus divides into secondary and tertiary bronchi, which continue to branch to smaller airways called the bronchioles. It conduct air into and out of lungs. Complete the labeling of the diagram of the upper respiratory structures (sagittal section). external nose, nasal cavity, pharynx, and associated structures (4) components of lower respiratory tract? The 10 most popular quizzes : 1 - the skeleton: test your knowledge of the bones of the full skeleton. NEW! Alveoli. The U-shaped hyoid bone, located just under the chin, is an important contributor to both respiratory and digestive processes. They are tiny sacs within our lungs that allow oxygen and carb…. 5 - the axial skeleton: How about the bones of the axial skeleton?. Bronchioles. The second half of the human airways, continuing after the larynx, including the trachea, bronchi, and the respiratory structures within Compare and contrast the functions of upper respiratory tract with the lower respiratory tract; ... A palatine tonsil is one of a pair of structures located laterally in the oropharynx in the area of the fauces. Find GCSE resources for every subject. The upper floor, the nasopharynx, is primarily a passageway for air and secretions from the nose to the oral pharynx. What Structures Are Located In The Lower Respiratory Tract? 4 - the skull: Do you know the bones of the skull?. A)the upper respiratory tract includes components of both functional portions B)the trachea is part of the lower respiratory tract but not of the bronchial tree C)stratified epithelia occur only in parts of the tract shared by another system 158 terms Jkouba22 ch 23 The Respiratory System The respiratory epithelium of the conducting airways consists of pseudostratified ciliated columnar epithelium. The bony upper- and lower-back parts of the septum are formed by the perpendicular plate of the ethmoid bone, and the vomer. bring oxygen rich air into the body for cells, expel waste products (CO2 & H2o) from the body, produce air flow that makes speech possible, first part of the respiratory system; consists of nose, mouth, pharynx, epiglottis, larynx & trache, consists of the bronchial tree (bronchi, bronchioles) and lungs; protected by the throacic cavity, wall of cartilage that divides the nose into two equal parts, air-filled cavity in a bone, lined with mucous membrane; several functions (1) make skull ligher, (2) produce sound, giving resonance to the voice, (3) produce mucus that drains into the nasal cavity; named for the bones in which they are located, located in the bones in the skull and connect to the nasal cavity; include the maxillary, frontal, ethmoid, sphenoid, aka the throat; the part of the respiratory system that immediately follows the nasal cavity, the first part of the pharynx; goes from the nose to the mouth, second part of the pharynx; part that you can see when you open your mouth; shared by the digestive & respiratory system, third part of the pharynx; continues to the opening of the esophagus and trachea, lid-like structure located @ the base of the tongue swings downward and closes off the laryngopharynx during swallowing so that food doesn't enter the trachea and lungs, aka voicebox; triangular chamber located between the pharynx and trache, largest cartilate that protects and holds the larynx open; aka Adam's Apple, create sounds when air is expelled from the lungs (when we talk or sing); seperate when we breath to let air pass through, aka windpipe; passageway for air from the larynx, extends from the neck into the chest; also held open by cartilage rings, consists of the bronchi and bronchioles; resembles a tree when truend upside down, two branches from the trachea that are passageways for air to the bronchioles, small division of the bronchi; brings air into the lungs, aka air sacs; small grape-like clusters found at the end of the each bronchiole; have thin, flexible walls that allow gas exchange between the CV & respiratory system (O2 & CO2), division of the lungs; right lung has 3 (superior, middle and inferior), left lung has two (superior& inferior), muscle that seperates the thoracic cavity from the abdomen; make breathing possible by expanding the cavity, stimulates the diaphragm and causes it to contract. 2. conduct air towards alveoli. Which … The structures of the Lower Respiratory Tract are (descending from the larynx): 1. 3 - the cell: learn the anatomy of a typical human cell. The trachea, bronchi, bronchioles, alveoli and lungs form the lower respiratory tract. Inhaled air is moistened, warmed, and cleansed by the tissue that lines the nasal cavity. The respiratory tract is a major portal of entry for toxic agents and is a common toxicological target site. The lingual tonsil is located at the base of the tongue. It is also connected to the tympanic cavity of the middle ear through the auditory tubes that open on both lateral walls. Compare and contrast the functions of upper respiratory tract with the lower respiratory tract The major organs of the respiratory system function primarily to provide oxygen to body tissues for cellular respiration, remove the waste product carbon dioxide, and help to maintain acid-base balance. What do the bronchi and bronchial network extend into? Figure 22.1.1 – Major Respiratory Structures: The major respiratory structures span the nasal cavity to the diaphragm. The mucus traps smaller particles like pollen or smoke. The Lower Respiratory Tract: The lower respiratory tract is responsible for absorbing the oxygen from the air collected by the upper respiratory tract and releasing the carbon dioxide from it. The respiratory system is lined with a mucous membrane that secretes mucus. Show transcribed image text. 13 6 14 10. into the lungs and terminates at the millions of alveoli, are one cell thick, which allows quick gas exchange with the capillaries, 3 lobes (superior lobe, middle lobe, inferior lobe); the horizontal fissure separates the right superior and right middle lobe, the oblique fissure separates the right inferior lobe with the remainder of the lung, 2 lobes (superior lobe and inferior lobe) to accommodate for the space required by the heart; the oblique fissure separates the left inferior lobe with the left superior lobe, pleural membrane to reduce the friction of surfaces when breathing, is a dome shaped structure that separates the thoracic and abdominal cavity.
