actions of the diaphragm during inhale/exhale
inhale - contracts & flattens
exhale - relaxes & moves upward
actions of the abdominal wall during inhale/exhale
inhale - relaxes & moves slightly outwards
exhale - contracts & pushes slightly inward
actions of the rib cage during inhale/exhale
inhale - moves upward & outward
exhale - moves downward & inward
what are the respective functions of the true & false vocal cords
True cords vibrate & produce sound
False cords protect true cords
what is the function of the nasal conchae/meati with respect to repiration?
enhance air turbulence, increase mucosal SA
function of soft palate during breathing
closes off nasal/airway passages during swallowing, lowers in breathing for air to pass in/out nose
function of epiglottis
switch btw larynx & esophagus to allow air to lungs/food to GI tract
lower esophageal (cardiac) sphinctor
relax for food to move into stomach
what is a pleural cavity
potential space btw vis/par pleura, filled with serous fluid
epithelia that lines the lungs, trachea, and pleural cavity
respiratory epithelium
pseudostratified ciliated columnar - squamous - non-ciliated
trace the passage of air in/out
- external nares
- nasal conchae
- internal nares
- pharynx (nasopharynx, oropharynx, laryngopharynx)
- glottis
- larynx
- epiglottis
- trachea
- primary bronchi
- secondary bronchi
- tertiary bronchi
- bronchioles
- terminal bronchioles
- alveolar ducts
- alveolar sacs
- alveoli
- alveoli walls
- bloodstream
then back
what structures do bile pass through
- R/L hepatic ducts
- common hepatic duct & cystic duct
- gallbladder
- common bile duct
- H-P sphincter
- duodenal papilla
- duodenum
what structures does pancreatic products pass thru
- pancreatic duct
- H-P sphincter
- duodenum
passage of food from lips to anus
- lips
- mouth
- pharynx
- esophagus
- cardiac sphincter
- stomach fundus/body
- pyloric sphincter
- duodenum
- jejunum
- ileum
- ileocecal valve
- cecum
- ascending colon
- transverse colon
- descending colon
- sigmoid colon
- rectum
- anal canal
- internal anal sphincter
- external anal sphincter
- anus
what are mesenteries
attach & support digestive organs by suspending them from posterior abdominal wall
mesentery proper - encloses jejunum/ileum
mesocolon - suspends transverse/sigmoid colon
three division of pharynx & location
- nasopharynx - space above soft palate
- oropharynx - space below soft palate to superior aspect of hyoid
- laryngopharynx - space below hyoid to glottis
three salivary glands and passage to mouth
- parotid - drain thru parotid duct to mouth
- submandibular - drain by mandibular duct to mouth
- sublingual - drain by sublingual duct to mouth
lip - location & affects of passage of food
surrounds the mouth
keeps food in oral cavity during chewing
soft palate - location & affects of passage of food
muscular flap posterior to hard palate
elevates & closes off nasal cavity during swallowing
epiglottis - location & affects of passage of food
on top of larynx, attached to thyroid cartilage
unattached portion moves & closes windpipe path
lower esophageal (cardiac) sphincter - location & affects of passage of food
inferior portion of esophagus
relaxes to allow bolus entry into stomach
pylorus - location & affects of passage of food
leftmost portion of stomach
prevents intestinal contents from reentering stomach when SI contracts
limits passage of large food particles/undigested material into intestine
ileocecal valve - location & affects of passage of food
btw small & large intestines
controls flow of chyme that enters cecum
anus - location & affects of passage of food
distal portion of the rectum
where food exits the body
structures/organs innervated by vagus nerve
pharynx, larynx, esophagus, stomach, heart, lungs, majority of GI tract
relationship btw vocal folds & vocal ligaments in larynx
vocal ligaments are elastic fibers that form the core/structural foundation of vocal folds
