FMA. 265130. Anatomical terminology. [ edit on Wikidata] The respiratory tract is the subdivision of the respiratory system involved with the process of conducting air to the alveoli for the purposes of gas exchange in mammals. [1] The respiratory tract is lined with respiratory epithelium as respiratory mucosa. [2]
The power series nose shape is generated by rotating the y = R(x/L)n curve about the x -axis for values of n less than 1. The factor n controls the bluntness of the shape. For values of n above about 0.7, the tip is fairly sharp. As n decreases towards zero, the power series nose shape becomes increasingly blunt.
93.93. MeSH. D012121. [ edit on Wikidata] Mouth-to-mouth resuscitation, a form of artificial ventilation, is the act of assisting or stimulating respiration in which a rescuer presses their mouth against that of the victim and blows air into the person's lungs.

Nasal cavity. The nasal cavity is a large, air-filled space above and behind the nose in the middle of the face. The nasal septum divides the cavity into two cavities, [1] also known as fossae. [2] Each cavity is the continuation of one of the two nostrils. The nasal cavity is the uppermost part of the respiratory system and provides the nasal ...
52745. Anatomical terms of bone. [ edit on Wikidata] The nasal bones are two small oblong bones, varying in size and form in different individuals; they are placed side by side at the middle and upper part of the face and by their junction, form the bridge of the upper one third of the nose . Each has two surfaces and four borders.
The nasal septum contains bone and hyaline cartilage. [3] It is normally about 2 mm thick. [4] The nasal septum is composed of four structures: Maxillary bone (the crest) Perpendicular plate of ethmoid bone. Septal nasal cartilage (ie, quandrangular cartilage) Vomer bone. The lowest part of the septum is a narrow strip of bone that projects ...
The aquiline nose was deemed a distinctive feature of some Native American tribes, members of which often took their names after their own characteristic physical attributes (i.e. The Hook Nose, or Chief Henry Roman Nose ). [5] In the depiction of Native Americans, for instance, an aquiline nose is one of the standard traits of the "noble ...
