Heating and cooling of a building can be modeled by the ODE T'=k1(T-Ta)+k(T-T)+P, where T=T(t) is the temperature in the building at time t, Ta the outside temperature, T the temperature wanted in the building, and P the rate of increase of T due to machines and people in the building, and k1 and k2 are (negative) constants. During exhalation, what happens to the length and volume of the thoracic cavity? The structure of the larynx is formed by several pieces of cartilage. The esophagus borders the trachea posteriorly. The alar cartilage consists of the apex of the nose; it surrounds the naris. Both the uvula and soft palate move like a pendulum during swallowing, swinging upward to close off the nasopharynx to prevent ingested materials from entering the nasal cavity. The act of swallowing causes the pharynx and larynx to lift upward, allowing the pharynx to expand and the epiglottis of the larynx to swing downward, closing the opening to the trachea. As the bronchioles become smaller and smaller, and nearer the alveoli, the epithelium thins and is simple squamous epithelium in the alveoli. Epiglottis Capillaries located just beneath the nasal epithelium warm the air by convection. An alveolus is approximately 200 m in diameter with elastic walls that allow the alveolus to stretch during air intake, which greatly increases the surface area available for gas exchange. _diaphragm_ 2) Identify It then enters the trachea. Identify the highlighted structure. The simple squamous epithelium formed by type I alveolar cells is attached to a thin, elastic basement membrane. See Answer Show transcribed image text Expert Answer 100% (2 ratings) The highlighted structure is made of what type of cartilage? Alveoli are connected to their neighbors by alveolar pores, which help maintain equal air pressure throughout the alveoli and lung (Figure 22.1.10). The carina is a raised structure that contains specialized nervous tissue that induces violent coughing if a foreign body, such as food, is present. http://141.214.65.171/Histology/Basic%20Tissues/Epithelium%20and%20CT/040_HISTO_40X.svs/view.apml? Interestingly, cold air slows the movement of the cilia, resulting in accumulation of mucus that may in turn lead to a runny nose during cold weather. The thick cricoid cartilage forms a ring, with a wide posterior region and a thinner anterior region. The uvula is a small bulbous, teardrop-shaped structure located at the apex of the soft palate.

The highlighted structure (scrotum) contains a layer of smooth muscle that wrinkles the skin under cold conditions to help maintain the temperature of the testes. In many cases, the underlying cause of the condition is unknown. Licensed under CC BY 4.0. Portions of the respiratory system are also used for non-vital functions, such as sensing odors, speech production, and for straining, such as during childbirth or coughing (Figure 22.1.1). The highlighted structure is lined by what type of epithelium? The major entrance and exit for the respiratory system is through the nose. In addition, the mucous membrane traps debris and pathogens. Anteriorly, the laryngopharynx opens into the larynx, whereas posteriorly, it enters the esophagus. The nasal passages contain the conchae and meatuses that expand the surface area of the cavity, which helps to warm and humidify incoming air, while removing debris and pathogens. The Chemical Level of Organization 2.0 Introduction 2.1 Elements and Atoms: The Building Blocks of Matter 2.2 Chemical Bonds As a result, the person may have problems with food or drink entering the trachea, and possibly, the lungs.

An olfactory epithelium used to detect odors is found deeper in the nasal cavity. The pharynx has three major regions. A true vocal cord is one of the white, membranous folds attached by muscle to the thyroid and arytenoid cartilages of the larynx on their outer edges. The second region is the oropharynx, which is continuous with the nasopharynx and is connected to the oral cavity at the fauces. This moist epithelium functions to warm and humidify incoming air. Do the external intercostals increase or decrease diameter of the thoracic cavity? The external nose consists of the surface and skeletal structures that result in the outward appearance of the nose and contribute to its numerous functions (Figure 22.1.2). For young children or individuals who have difficulty using an inhaler, asthma medications can be administered via a nebulizer. (c) nonmathematical thinking. Air enters two openings, the external nares (nostrils; singular, naris), and passes into the vestibule and . Asthma is common condition that affects the lungs in both adults and children.

The pharyngeal tonsils are large in children, but interestingly, tend to regress with age and may even disappear. ciliated pseudostratified columnar epithelium. By the end of this section, you will be able to: 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. breathing at an abnormally slow rate, resulting in an increased amount of carbon dioxide in the blood. The apex is the tip of the nose. If a persons epiglottis were injured, this mechanism would be impaired. Kumar V, Ramzi S, Robbins SL. Approximately 8.2 percent of adults (18.7 million) and 9.4 percent of children (7 million) in the United States suffer from asthma. An alveolar duct is a tube composed of smooth muscle and connective tissue, which opens into a cluster of alveoli. Anatomy and Physiology questions and answers. Chapter 1. Similar to the pharyngeal tonsil, the palatine and lingual tonsils are composed of lymphoid tissue, and trap and destroy pathogens entering the body through the oral or nasal cavities. This is a blood-air barrier through which gas exchange occurs by simple diffusion. This problem has been solved! Answer Alveolar sacs - They are the components of respiratory zone of the respiratory tract. 3. From a functional perspective, the respiratory system can be divided into two major areas: the conducting zone and the respiratory zone. If a person sustains an injury to the epiglottis, what would be the physiological result? The conducting zone consists of all of the structures that provide passageways for air to travel into and out of the lungs: the nasal cavity, pharynx, trachea, bronchi, and most bronchioles. http://erj.ersjournals.com/gca?submit=Go&gca=erj%3B37%2F5%2F1037&allch=, Creative Commons Attribution-ShareAlike 4.0 International License, List the structures that make up the respiratory system, Describe how the respiratory system processes oxygen and CO, Compare and contrast the functions of upper respiratory tract with the lower respiratory tract. Endocrine System Analysis The endocrine system is made up of glands, which are located throughout the body and secrete hormones into the blood (Herlihy, 2014). The nasal septum divides the nasal cavity into right and left sides. What happens to the length of the thoracic cavity when the diaphragm is relaxed? The epithelium of the nasal passages, for example, is essential to sensing odors, and the bronchial epithelium that lines the lungs can metabolize some airborne carcinogens. The highlighted structure gets its name because it leaves room for what organ? The conducting zone of the respiratory system includes the organs and structures that are not directly involved in gas exchange, but perform other duties such as providing a passageway for air, trapping and removing debris and pathogens, and warming and humidifying incoming air. On either side of the apex, the nostrils are formed by the alae (singular = ala). Identify the highlighted structure. A palatine tonsil is one of a pair of structures located laterally in the oropharynx in the area of the fauces. The laryngopharynx is connected to the oropharynx and the esophagus and trachea. Symptoms of a severe asthma attack that requires immediate medical attention would include difficulty breathing that results in blue (cyanotic) lips or face, confusion, drowsiness, a rapid pulse, sweating, and severe anxiety. The Chemical Level of Organization, Chapter 3. Prostate. At the top of the nasopharynx are the pharyngeal tonsils. The organs of the urinary system are organs of excretionthey remove wastes and water from the body. The larynx is a cartilaginous structure inferior to the laryngopharynx that connects the pharynx to the trachea and helps regulate the volume of air that enters and leaves the lungs (Figure 22.1.6). The oropharynx contains two distinct sets of tonsils, the palatine and lingual tonsils. Are the highlighted vessels carrying oxygenated or deoxygenated blood? The conchae and meatuses also conserve water and prevent dehydration of the nasal epithelium by trapping water during exhalation. Philadelphia (PA): Elsevier Ltd; 2005. Each paranasal sinus is named for its associated bone: frontal sinus, maxillary sinus, sphenoidal sinus, and ethmoidal sinus. The major respiratory structures span the nasal cavity to the diaphragm. Differences in surface water and deep water temperature can be utilized for power generation. The highlighted larynx is protected from food and liquid by what elastic cartilage structure?

In addition, excessive mucus secretion can occur, which further contributes to airway occlusion (Figure 22.1.11). Length of thoracic cavity and volume increase. Kidneys Filter Blood at the Top of the Urinary System. Portions of the respiratory system are also used for non-vital functions, such as sensing odors, speech production, and for straining, such as coughing. Similar to the nasal cavity and nasopharynx, this specialized epithelium produces mucus to trap debris and pathogens as they enter the trachea. The alveolar wall consists of three major cell types: type I alveolar cells, type II alveolar cells, and alveolar macrophages. The floor of the nasal cavity is composed of the palate. The nasal bone articulates superiorly with the frontal bone and laterally with the maxillary bones. increases the concentration of carbon dioxide in the blood and decreases the blood's pH (a condition generally called acidosis).

We review their content and use your feedback to keep the quality high. The laryngopharynx is inferior to the oropharynx and posterior to the larynx. Several structures within the conducting zone perform other functions as well. (black arrow), In pulmonary ventilation, air flows between the atmosphere and the alveoli of the lungs because of alternating pressure differences created by contraction and relaxation of respiratory muscles, Movement of oxygen from alveloiinto pulmonary capillaries and CO2 from pulmonary capillaries, movement of oxygen from capillaries into body cells and CO2 from body cells into capillaries, Abdominal Muscles and Internal Intercostal Muscles are used, amt. The fauces is the opening at the connection between the oral cavity and the oropharynx. Anatomy and Physiology: The Unity of Form and Function, Human Anatomy and Physiology (NASTA Edition). The highlighted structure separates the nasal cavity from which region of the pharynx? The trachea is lined with pseudostratified ciliated columnar epithelium, which is continuous with the larynx. Three smaller, paired cartilagesthe arytenoids, corniculates, and cuneiformsattach to the epiglottis and the vocal cords and muscle that help move the vocal cords to produce speech. Roaming around the alveolar wall is the alveolar macrophage, a phagocytic cell of the immune system that removes debris and pathogens that have reached the alveoli. The conducting zone of the respiratory system includes the organs and structures not directly involved in gas exchange. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Describe the three regions of the pharynx and their functions. 1.
