aldosterone is secreted in response to

low Na in the blood and low blood pressue
the pancreas secretes glucagon when

blood is low in glugose
the parathyroid gland controls

the amount of calcium in the blood
the adrenal cortex secretes

DHEA
gastrin is secreted by the ___ in response to the ___.
- stomach
- presence of food
the upper chambers of the heart are termed ___ and contain ___
- atria
- pectinate muscle
what is associated with arteries but not veins

internal elastic membrane
the left ventricle is associated with which valves
- bicuspid, mitra, l. atrioventricular valve
- aortic semilunar valve
the right lymphatic duct drains lymph from

the right upper portion of the body
the secondary line of defense of the immune system involves

inflammatory chemicals tat kill everything in the infected area
what would resould of exporation of air out of the lungs
- relaxation of the diaphragm
- contracton of the internal intercostals
- reaxation of the external intercostals
air out of the lungs

alveolus - alveolar duct - bronchioles - tertiary bronchus - secondary bronchus - primary bronchus - carina - trachea
a sheet of connective tissue that lines the thoracic cavity

parietal pleura
pericardial membranes
- secrete pericardial fluid
- are used to decrease friction from the pumping action of the heart
the atrioventricular node is located in the

right atrium
the lymphatic system
- returns waste filled tissue fluid back to the blood
- is used to absorb fat from the digestive system
- filters tissue fluids to remove debris and dead cells
- works with the immune system to kill bacteria
- and does NOT remove co2 from the blood
the pulmonary arteries carry

blood high in co2 and low in 02
atrioventricular node is respnsible for

passing the action potential from the SA node to the AV bundle
if the pleural membrane is punctured

air rushes into the thorasic cavity, collapsing the lungs and causing difficulty in breathing
the hypothalamus

makes releasing and inhibiting hormones
the veins and arteries of the hypothalamus and pituitary gland

carry releasing and inhibiting hormones to the anterior pituitary
the posterior pituitary

makes and releases ACTH GH and PRL
the anterior pituitary

stores and releases oxytocin and ADH
layers of an artery in to out

enothelium - basement membrane - internal elastic lamina - tunica media - tunica externa
layers of the heart in to out

endocardium - myocardium - serous visceral pericardium - fibrous parietal pericardium
structures in the nasal cavity; passageways between em
lined with
- nasal conche; nasal meati
- pseudostratified ciliated columnar epithelium
mechanics of breathing
- diaphragm contracts
- external intercostals contract
- inhalation
- relaxation leads to exhalation
antidiuretic hormone

results in reabsorbtion of water
erythopoietin
- causes kidney to reabsorb water and sodium
- secreted when anemic to stimulate the bone marrow to make more rbc
parathyroid hormone

enhances calcium reabsortion of the kidney
FSH

causes estrogen secretion in females
LH

causes testosterone secretion males
PRL

causes milk to be manufactured
glucagon

increases blood glucose
r and l coronary arteries

carry 02 blood to the myocardium
r and l posterior communicating arteries

are part of the circle of willis
pulmonary veins

carry 02 blood to the left atrium
l internal carotid artery

carries 02 blood to the circle of willis
passageway a oxygen molecule would take

external nares - vestibule - nasal cavity- nasal conche and meatus - nasopharynx - oropharynx - laryngopharynx- epiglottis- larygngeal cartilage and vocal flods- rima glottis- cricothyoid ligament ad cricoid cartilage- trachea- carina- primary bronchus- seconday bronchus tertiary bronchus- bronchiole- alveolar duct- alveolus- simple squamous epithelium- basement membrane- simple squamous epi of capillary- capillary lumen
