• Dorsum nasi


  The length of the nose
• The root


  The region of the nose located between the eyebrows
• Philtrum


  The concave surface that connects the apex of the nose to the upper lip
• ethmoid bone


  The nasal septum is formed posteriorly by the perpendicular plate of the
• Nasopharynx


  Flanked by the conchae of the nasal cavity and serves only as an airway
• fauces


  The opening at the connection between the oropharynx and the oral cavity
• Uvula


  A small bulbous, teardrop-shape structure
• epiglottis


  A very flexible piece of cartilage that covers the opening of the trachea
• type 1 alveolar cell


  Squamous epithelial cell of the alveoli, which makes up 97% of the surface area
• type 2 alveolar cell


  Secretes pulmonary surfactant
• High; low


  Gas moves from an area of high partial pressure to an area of low partial pressure
• internal respiration


  Gas exchange that occurs at the level of the tissue
• The partial pressure of oxygen in the tissues is low because
• Partial pressure of oxygen in the alveoli is 104mmHg, whereas its partial pressure in the blood is about 40mmHg

  This causes oxygen to rapidly cross the respiratory membrane from alveoli into the blood
• When oxygen binds to a hemoglobin molecule

  The affinity of the other hemoglobin molecules for oxygen increases
• Which of the following factors play a role in the oxygen-hemoglobin saturation dissociation curve?
• During the chloride shift

  Bicarbonate is removed from the erythrocyte
• small intestine


  The organ of digestive tract where most digestion and absorption occurs
• stomach


  The organ of the digestive tract where digestion of proteins is initiated
• large intestine


  The primary function is to finish the absorption of the water and nutrients
• mouth


  The organ of the digestive tract where digestion of starch is initiated
• incisors


  The teeth responsible for slicing through food
• molars


  The teeth responsible for grinding through food
• muscularis


  The layer of the alimentary canal responsible for moving food through the canal
• submucosa


  Includes blood and lymphatic vessels which transport absorbed nutrients
• liver


  Bile is produced by the
• cardiac sphincter


  Food passes from the esophagus to stomach at the
• pyloric sphincter


  Food passes from the stomach to the small intestine at the
• duodenum


  Secretions from the liver and pancreas enter the alimentary canal at the
• small intestine


  In the, chemical digestion occurs not only in lumen, but also on the luminal surfaces of mucosal cells
• parietal


  Cells of the gastric glands secrete HCL and intrinsic factor
• During the gastric phase, distention of the stomach activates stretch receptors

  Which inhibits secretion of gastric juices
• Pylorus


  Which holds about 30ml of chyme, acts as a filter, permitting only liquids and small food particles to pass to the small intestine
• Fundus AND Body


  Cells of the produce most gastric secretions
• lacteals


  Triglycerides in the lumen are absorbed by
• Lingual lipase is activated in the stomach by

  HCL
• The hormone, gastrin
• Villi


  Hairlike vascularized projections of the small intestine are called
• chief


  Cells of the gastric glands secrete pepsinogen
• hepatic flexure
