Encovers the glottis Back to Main Screen Upper or Lower? Pharnyx, larnyx, alveoli, bronchi, bronchioles, trachea Back to Main Screen Pharnyx-U laryx-L alveoli-L bronchi-L bronchioles-L trachea-L Describe Boyle’s Law Pressure and volume are inversely related Back to Main Screen Ciliated or simple squamous? Nasal cavityalveolibronchiolessuperior pharnyx- Nasal cavity- ciliated alveoli- simple sq. bronchioles- simple sq. superior pharnyx- ciliated Back to Main Screen Why are alveoli so efficient at gas exchange?(4 reasons) Diff. in partial pressure, gases are lipid soluble, large SA, close proximity of bl. to alveloi Back to Main Screen The main agonist for inhalation is… diaphragm Back to Main Screen Gas that is in highest concentration in expired air? nitrogen Back to Main Screen Compare surfactant and pleural fluid Surfactant- alveoli, reduces surface tension; pleural fluid- pleural cavity, reduces friction Back to Main Screen Explain how muscle contraction influences breathing - Inhalationincreases volume of thoracic cavity causes decrease in pressure Back to Main Screen List all the body cavities that the heart is found in Pericardial, mediastinum, thoracic, ventral Back to Main Screen When winking you mainly use Orbicularis oculi Back to Main Screen Muscles of mastication include Masseter, temporalis Back to Main Screen Extender of the forearm triceps Back to Main Screen Orgin of gluteus maximus Iliac crest Back to Main Screen Name 2 calf muscles starting with the most superficial Gastronemius soleus Back to Main Screen Name the 3 main muscles of hamstring group Semimembraneous, semitendinous, biceps femoris Back to Main Screen The innermost adductor muscle in the thigh gracilis Back to Main Screen Muscle involved in head rotation Sternocleidomastoid Back to Main Screen Major abductor of humerous deltoid Back to Main Screen List the abdominal muscle layers (staring with most superficial) External oblique, internal oblique, rectus abdominis, transverse abdominus Back to Main Screen Name the orgin and insertion for the following trapezius, rhomboids Trapeziusorigins-occipital bone, spinous process rhomboids- origin-spinous process insertion-scapula for both Back to Main Screen Bile digests fats Back to Main Screen List the layers of the digestive system (inner to outer) Mucosa, submucosa, muscular, serosa Back to Main Screen Name at least 3 muscles in “quad” rectus femoris vastus lateralis vastus intermedius vastus medialis Back to Main Screen 3 main functions of large intestine Adsorption of water, adsorption and production of vitamins, storage of feces Back to Main Screen Location of pyloric sphincter stomach Back to Main Screen Name the digestive organ that plays a role in the chemical digestion of all types of organic compounds pancreas Back to Main Screen Name the sections of the small intestine in the correct order. Duodenum, jejunem, ilium Back to Main Screen The location and function(s) of parietal cells Back to Main Screen StomachHCl and intrinsic factor Name the and give the # of each type of tooth Incisors-8 Cuspids-4 Bicuspids-8 Molar-12 Back to Main Screen
