respiratory anatomy

• Alveolar macrophages are phagocytes that remove foreign material from the alveolar spaces that may not have been swept out by the cilia of the bronchial tree.
• Anatomy & Physiology Respiratory System describes the structure and functions of the nasal cavities and pharynx.
• Vocal folds, also known as "true vocal cords", are a pair of tissues that in the creation of sound CNX: they invade the muscles at a touch.
• Glotis, the slit-like passageway between the vocal folds, allows sound to pass through.
• Anatomy & Physiology Respiratory System describes the structure of the larrynx and explains the speaking mechanism.
• Anatomy & Physiology Respiratory System describes the structure and functions of the trachea and bronchi.
• Anatomy & Physiology Respiratory System describes the location of the pleural membranes, and explains the functions of serous fluid.
• Vestibular folds, also known as false vocal cords, are not involved in producing sound, it's their movement, along with the vocal folds, that regulates the flow of air into and out of the glottis.
• The larnyx, also known as the windpipe, is the main airway to enter the lungs.
• Obstruction is fatal.
• The larnyx is lined with cartilage and is covered with mucous membrane.
• Conducting zone functionals consist of tubes and tissues within the lungs where actual gas exchange occurs.
• Respiratory zone is a specialized organ at the entrance of the respiratory system NOSE.
• Respiratory zone is divided into an external portion and an internal portion.
• External portion of the respiratory zone is the portion visible on the face and consists of bone and cartilage covered with skin and lined with mucous membrane.
• Internal portion of the respiratory zone lies in and posts to the external nose and is continuous with the pharynx.
• Internal portion of the respiratory zone is also lined with mucous membrane.
• Anatomy & Physiology Respiratory System describes the structure of the alveolar volume and defines each.
• Anatomy & Physiology Respiratory System describes the importance of normal inhalation and exhalation, and forced exhalation.
• Alveolar ducts branch out from the respiratory bronchioles, are surrounded by numerous alveolar respiratory capillaries, and are surrounded by alveolar walls.
• Alveolar ducts are arranged in a specific structure known as the respiratory zone.
• Alveolar ducts, singular alveolus, are arranged in sacs with capillaries, and are surrounded by alveolar walls.
• Alveolar type I cells, or "pneumocytes", are the most abundant alveolar cells and are simple squamous epithelial cells that make up the walls of alveoli.
• Alveolar type I cells help form the main site for gas exchange in the respiratory membrane.
• Protection functions provide protection against some microorganisms by preventing their entry into the body and by removing them from respiratory surface structures such as the nose, pharynx, larynx, trachea, bronchi, bronchioles, and lungs.
• Structural divisions include the nose, nasal cavity, pharynx, and associated structures.
• Prepares the air for entry into the lower respiratory tract by trapping and filtering out microorganisms.
• Functional divisions include the larynx, trachea, bronchi, bronchioles, and associated structures.
• Functions as a filter, warmer, and moistener of air as it enters the lungs.
• Structural divisions include the lungs and associated structures.
• Functional divisions include the pleura, muscles of respiration, and associated structures.
• Anatomy & Physiology Respiratory System describes the normal inhalation and exhalation volumes and forced exhalation volumes.
• The esophagus is where food and drink enter the body, while the larynx is where air enters the body.
• The esophagus is often referred to as the "voice box".
• The esophagus connects the pharynx.
• The larynx is part of the larynx.
• The larynx contains the trachea.
• Most of the larynx is lined with cartilage.
• The larynx is commonly referred to as the "Adam's apple".
• The cricoid cartilage forms the inferior wall of the larynx.
