Rationales
Included
, Mechanics for breathing and muscles used Lung expansion - pleura: two thin, smooth layers of tissue with thin film of fluid in
between allow frictionless movement across one another.
Inhalation: Chest expands, creates negative pressure in thoracic cavity, parietal
pleura pulls the visceral, which pull the lungs.
Exhalation: Diagphragm/intercostals relax, thoracic cage contracts, pressure in
cavity rises, air is expelled. Normally passive. No energy required. Exhaled air
contains 16% o2.
Diaphragm: primary muscle for respiration. Usually involuntary but can be
controlled voluntarily. Esophagus and great vessels pass through the diaphragm.
Dome shaped until contraction during inhalation; moves down and expands the
size of the thoracic cavity.
Intercostal muscles.
Alveoli All airway structures serve to get air to this point. Only place where o2 and co2
are exchanged. Contact w/ pulmonary capillaries. Pulmonary capillaries diffuse
cabon dioxide from the body to the alveoli. Alveloi diffuse o2 from respiratory
system to the body. Surfactant is: a substance that helps keep the alveoli from
collapsing.
What each number in BP represent Systolic: the pressure exerted during contracted of the left ventricle.
Diastolic: the pressure between contractions. The resting phase. This is constant.
Characteristics and differences of types of muscle tissue Smooth: involuntary located within the blood vessels and digestive tract.
Skeletal: voluntary that attaches to the skeleton.
Cardiac: heart
Diaphragm and intercostals are involuntary but are can also be voluntary.
Locations/function of liver Think filter. Remember antifreeze OD and whiskey. RUQ. Helps break down fats,
filters toxins, prodcues cholesterol.
Location/function of spleen LUQ. Filters the blood and helps repair damaged blood platelets.
Location/function of pancreas Aids in digestion, produces insulin, helps regulate CBG levels. Epigastric region.
Location/function of esophagus Collapsible structure running from mouth to stomach. Posterior to the trachea.
Location/function of stomach Hollow LUQ. Receives food, begins breaking it down, sends it to small intestine.
Location/function of small intestine Hollow, both lower quadrants. Food from stomach is mixed w/ digestive enzymes
to digest fat. Most contents are absorbed out of the small intestine and
used/stored by the body.
Location/function of large intestine Occupies outer boarder of abd. Pulls most of the remaining liquid to form solid
stool.
Location/function of appendix Hollow, RLQ, can easily become obstructed, causing inflammation, rupture,
possible infection
Location/function of Kidneys Part of urinary system. Control fluid balance, filter waste, control pH balance.
