Immune cells that patrol the connective tissue deep to the respiratory epithelium provide additional protection. A thin connective tissue called the renal capsule surrounds each kidney. Several bones that help form the walls of the nasal cavity have air-containing spaces called the paranasal sinuses, which serve to warm and humidify incoming air. Serous and mucus-producing cells also secrete the lysozyme enzyme and proteins called defensins, which have antibacterial properties. The cilia of the respiratory epithelium help remove the mucus and debris from the nasal cavity with a constant beating motion, sweeping materials towards the throat to be swallowed. Folds in males tend to be larger than those in females, which create a deeper voice. We review their content and use your feedback to keep the quality high. The uvula is a small bulbous, teardrop-shaped structure located at the apex of the soft palate. The thyroid cartilage is the largest piece of cartilage that makes up the larynx. The function of the pharyngeal tonsil is not well understood, but it contains a rich supply of lymphocytes and is covered with ciliated epithelium that traps and destroys invading pathogens that enter during inhalation.

Anteriorly, the laryngopharynx opens into the larynx, whereas posteriorly, it enters the esophagus. 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). Functionally, the respiratory system can be divided into a conducting zone and a respiratory zone. The sinuses produce mucus and lighten the weight of the skull. The Cellular Level of Organization, Chapter 4. As the nasopharynx becomes the oropharynx, the epithelium changes from pseudostratified ciliated columnar epithelium to stratified squamous epithelium. Q. 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. Each paranasal sinus is named for its associated bone: frontal sinus, maxillary sinus, sphenoidal sinus, and ethmoidal sinus.

When discussing the nose, it is helpful to divide it into two major sections: the external nose, and the nasal cavity or internal nose. The respiratory zone includes the structures of the lung that are directly involved in gas exchange: the terminal bronchioles and alveoli. Several structures within the conducting zone perform other functions as well. An ala is a cartilaginous structure that forms the lateral side of each naris (plural = nares), or nostril opening. The highlighted structure is anchored anteriorly to the thyroid cartilage and posteriorly to the _____________. The conchae and meatuses also conserve water and prevent dehydration of the nasal epithelium by trapping water during exhalation. The pharynx is divided into three major regions: the nasopharynx, the oropharynx, and the laryngopharynx (Figure 22.1.5). Rings of cartilage, similar to those of the trachea, support the structure of the bronchi and prevent their collapse. One bronchus enters each lung. (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. An alveolar sac is a cluster of many individual alveoli that are responsible for gas exchange. It then enters the trachea. The first region is the nasopharynx, which is connected to the posterior nasal cavity and functions as an airway. The thyroid cartilage consists of the laryngeal prominence, or Adams apple, which tends to be more prominent in males. 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. This is a blood-air barrier through which gas exchange occurs by simple diffusion. However, recent research has demonstrated that certain viruses, such as human rhinovirus C (HRVC), and the bacteria Mycoplasma pneumoniae and Chlamydia pneumoniae that are contracted in infancy or early childhood, may contribute to the development of many cases of asthma.

The gas exchange occurs in the respiratory zone. increases the concentration of carbon dioxide in the blood and decreases the blood's pH (a condition generally called acidosis). The organs of the urinary system are organs of excretionthey remove wastes and water from the body. 2003-2022 Chegg Inc. All rights reserved. The bridge is the part of the nose that connects the root to the rest of the nose. The alar cartilage consists of the apex of the nose; it surrounds the naris. The inner edges of the true vocal cords are free, allowing oscillation to produce sound. A link between chronic asthma and chronic infection. This muscular wall can change the size of the tubing to increase or decrease airflow through the tube. Alveoli are connected to their neighbors by alveolar pores, which help maintain equal air pressure throughout the alveoli and lung (Figure 22.1.10). Epiglottis Compare and contrast the conducting and respiratory zones. As a result, the person may have problems with food or drink entering the trachea, and possibly, the lungs. Air enters two openings, the external nares (nostrils; singular, naris), and passes into the vestibule and . Specifically, oxygen moves from the outside air into the body; and water vapor, carbon dioxide, and other waste gases move from inside the body into the outside air. The major entrance and exit for the respiratory system is through the nose.

The epididymis is found on the posterior surface of the testes, and sits along the entire length of the posterior testes. to explore the tissue sample in greater detail. Underneath the thin skin of the nose are its skeletal features (see Figure 22.1.2, lower illustration). The nasal septum is formed anteriorly by a portion of the septal cartilage (the flexible portion you can touch with your fingers) and posteriorly by the perpendicular plate of the ethmoid bone (a cranial bone located just posterior to the nasal bones) and the thin vomer bones (whose name refers to its plough shape). In addition, the mucous membrane traps debris and pathogens. The inferior conchae are separate bones, whereas the superior and middle conchae are portions of the ethmoid bone. http://141.214.65.171/Histology/Basic%20Tissues/Epithelium%20and%20CT/040_HISTO_40X.svs/view.apml?
