Deep in the lungs, each bronchus divides into secondary and tertiary bronchi, which continue to branch to smaller airways called the bronchioles. They are tiny sacs within our lungs that allow oxygen and carb…. first part of the respiratory system; consists of nose, mouth, pharynx, epiglottis, larynx & trache lower respiratory tract consists of the bronchial tree (bronchi, bronchioles) and lungs; protected by … The respiratory system can be divided into the, nose, nasal cavity, mouth, pharynx, and larynx, the airway, lungs, and respiratory muscles, nose, nasal cavity, mouth, pharynx (throat), larynx (voice box), trachea (windpipe), bronchi, and bronchial network, cilia that trap the microbes & debris and sweep them back to the mouth. 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. Which … Primary Bronchi. The lower airways or lower respiratory tract includes the portion of the larynx below the vocal folds, trachea, bronchi and bronchioles. Secondary and tertiary bronchi. Inhaled air is moistened, warmed, and cleansed by the tissue that lines the nasal cavity. The upper respiratory tract is composed of the structures that are located outside the chest cavity or thorax, including the nose, nasopharynx, oropharynx, laryngopharynx, and larynx. Complete the labeling of the diagram of the upper respiratory structures (sagittal section). Epiglottis; thyroid cartilage (adam's apple); vestibular folds; vocal cords (glottis) Larynx structures. 2 - the brain: can you name the main anatomical areas of the brain?. -15 11 12. The overall function of the upper respiratory tract is to provide a pathway for air to reach the lower respiratory tract, where gas exchange occurs. Functionally, the respiratory system can be divided into a conducting zone and a respiratory zone. The first half of the airways in human respiratory system, the upper respiratory tract consists of Any prolonged blockage, even for a few minutes, can cause death. 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. 18 16 1917 20 19. The bony upper- and lower-back parts of the septum are formed by the perpendicular plate of the ethmoid bone, and the vomer. The lower respiratory system is a hierarchical system that can be divided into two functional and structural components: the conducting tract (airways) and the respiratory zone. 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. The mucus traps smaller particles like pollen or smoke. 16 13 17 15. The nostrils, nasal cavity, mouth, pharynx, and larynx form the upper respiratory tract. The respiratory mucosa consists of epithelium and underlying layer of areolar tissue. 3 - the cell: learn the anatomy of a typical human cell. The organs in each division are shown in the figure below. Flap of tissue that guards the superior opening of the larynx; at rest, stand almost vertically; during swallowing, closes airway like a trap door and directs food to the esophagus behind it. In the respiratory system, structures that produce sound depend on the hyoid. Bronchi (one bronchus into each lung) 3. conduct air towards alveoli. As the names imply, the upper respiratory tract consists of everything above the vocal folds, and the lower respiratory tract includes everything below the vocal folds. external nose, nasal cavity, pharynx, and associated structures (4) components of lower respiratory tract? Anatomy of the exercise36 Respiratory System Review Sheet 36 283 Upper and Lower Respiratory System Structures 1. Human respiratory system - Human respiratory system - The pharynx: For the anatomical description, the pharynx can be divided into three floors. It conduct air into and out of lungs. The upper floor, the nasopharynx, is primarily a passageway for air and secretions from the nose to the oral pharynx. The respiratory tract has two major divisions: the upper respiratory tract and the lower respiratory tract. Secondary (labor) Bronchi. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Other structures, namely the thoracic cage (or rib cage) and the diaphragm, protect and support these functions. NEW! The upper respiratory tract comprises the nasopharyngeal and laryngeal tissues. 4, Bronchioles. The structures of the Lower Respiratory Tract are (descending from the larynx): 1. The lower respiratory system, or lower respiratory tract, consists of the trachea, the bronchi and bronchioles, and the alveoli, which make up the lungs. The conducting tract consists of airways that transport gases into and out of the … 6 - the heart: name the parts of the human heart larynx, trachea, bronchi, and passageways in lungs external nose (location, function) Label the anatomy of the lower respiratory system. Other structures of the respiratory tract are the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles. 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 … Hairlike structures called cilia line the mucous membrane and move the particles trapped in the mucus out of the nose.
