Details of upper respiratory tract. The upper respiratory tract can refer to the parts of the respiratory system lying above the vocal folds, or above the cricoid cartilage. [4] [5] The larynx is sometimes included in both the upper and lower airways. [6] The larynx is also called the voice box and has the associated cartilage that produces sound.
The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...
Upper respiratory system, with soft palate labeled near center. The soft palate (also known as the velum, palatal velum, or muscular palate) is, in mammals, the soft tissue constituting the back of the roof of the mouth. The soft palate is part of the palate of the mouth; the other part is the hard palate. The soft palate is distinguished from ...
The lungs as main part of respiratory tract. The lower respiratory tract is part of the respiratory system, and consists of the trachea and the structures below this including the lungs. [34] The trachea receives air from the pharynx and travels down to a place where it splits (the carina) into a right and left primary bronchus.
Upper respiratory system, with the nasopharynx, oropharynx and laryngopharynx labeled at left. The upper portion of the pharynx, the nasopharynx, extends from the base of the skull to the upper surface of the soft palate. [2] It includes the space between the internal nares and the soft palate and lies above the oral cavity.
The human nose is the first organ of the respiratory system. It is also the principal organ in the olfactory system. The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two. The nose has an important function in breathing.
t. e. Respiratory epithelium, or airway epithelium, [1] is a type of ciliated columnar epithelium found lining most of the respiratory tract as respiratory mucosa, [2] where it serves to moisten and protect the airways. It is not present in the vocal cords of the larynx, or the oropharynx and laryngopharynx, where instead the epithelium is ...
The epiglottis (pl.: epiglottises or epiglottides) is a leaf-shaped flap in the throat that prevents food and water from entering the trachea and the lungs. It stays open during breathing, allowing air into the larynx. During swallowing, it closes to prevent aspiration of food into the lungs, forcing the swallowed liquids or food to go along ...
