mouth
pharynx
larynx
trachea
bronchi
bronchial network
what is the function of alveoli? answersallows for exchange of gas
the right lung has how many lobes? answers3
left lung has how many lobes? answers2
what is the function of pleural membrane? answersreduces friction when you breath
what are the respiratory muscles? answersdiaphragm
intercostal muscles
what are the functions of respiratory system? answers- supply O2 through body
- get rid of CO2
- filters air
- speech
- smell (think chemoreceptors)
- helps maintain homeostasis
Hyper or Hypoventilation: increases blood pH (acidosis) answersHyperventilation
Hyper or Hypoventilation: decreases blood pH (alkalosis) answersHypoventilation
Inhalation or Exhalation?
- diaphragm contracts, moves down, increasing chest cavity, pressure decreases
,- outside air is under more pressure than air inside lungs answersinhalation
Inhalation of exhalation?
- diaphragm/intercostals relax, chest cavity decreases
- controlled by medulla oblongata answersexhalation
_________________________________ monitors the level of CO2 in blood, signals
breathing rate when levels are too high answersmedulla oblongata
circulatory system consists of what 3 major parts? answers- blood
- blood vessels
- heart
___________, this system cleans up excess fluids and proteins, returning them to
circulatory system answerslymph vascular system
name the walls of blood vessels: answerstunica intima
tunica media
tunica adventitia
function of blood: answers- helps maintain internal environment by carrying raw
materials
- removes waste
- helps stabilize pH
- hold 5qts of blood
blood is composed of: answersRBC
WBC
platelets
plasma
function of red blood cells: answerstransports o2 to cells
how long can RBC live up to? answers4 months
where does RBC form? answersin bone marrow
function of WBC: answersdefend against infection
removes wastes
forms platelets for coagulation
name 5 types of WBC answersN.E.M.B.L
neutrophils
eosinophils
monocytes
basophils
, lymphocytes
heart is made of what tissue? answerscardiac muscle tissue
this tissue is "self-exciting" answerscardiac muscle tissue
what separates the atrium from ventricle? answersatrioventricular valve
___________________ prevent backflow answersvalves
the heart has how many chambers? answers4
what is the function of the sinoatrial node "cardiac pacemaker"? answers- generates
electrical signals through purkinje fibers, stimulating contraction to fill R ventricle with
blood
- SA node transmits signal to right ventricle through AV valve (tricuspid)
- R ventricle contracts
- AV valve closes, pulmonary semilunar valve opens
- blood pumped out of arteries to lungs
- blood from lungs fills left atrium
- mitral valve (bicuspid) opens, blood fills ventricle
- mitral valve closes and aortic semilunar valve opens
- left ventricle contracts, blood is pumped out of aorta and to rest of body
circulation: blood to heart answerscoronary
circulation: blood between heart and lungs answerspulmonary
circulation: blood to entire body answerssystemic
circulation:
flow of blood from digestive system to liver, then heart answersportal
circulation: flow of blood between heart and kidneys answersrenal
Name all the types of circulation systems: answerscoronary
pulmonary
systemic
portal
renal
arteries or arterioles: where adjustments are made in blood delivery answersarterioles
What are capillary beds? answersdiffusion sites for exchanges between blood and
interstitial fluid
