Upper respiratory tract consists of - nose
nasal cavity
mouth
pharynx
larynx
lower respiratory tract consists of - trachea
lungs
bronchial tree
airway consists of - nose
nasal cavity
mouth
pharynx
larynx
trachea
bronchi
bronchial network
what is the function of alveoli? - allows for exchange of gas
the right lung has how many lobes? - 3
left lung has how many lobes? - 2
what is the function of pleural membrane? - reduces friction when you breath
,what are the respiratory muscles? - diaphragm
intercostal muscles
what are the functions of respiratory system? - - supply O2 through body
- get rid of CO2
- filters air
- speech
- smell (think chemoreceptors)
- helps maintain homeostasis
Hyper or Hypoventilation: increases blood pH (acidosis) - Hyperventilation
Hyper or Hypoventilation: decreases blood pH (alkalosis) - Hypoventilation
Inhalation or Exhalation?
- diaphragm contracts, moves down, increasing chest cavity, pressure decreases
- outside air is under more pressure than air inside lungs - inhalation
Inhalation of exhalation?
- diaphragm/intercostals relax, chest cavity decreases
- controlled by medulla oblongata - exhalation
_________________________________ monitors the level of CO2 in blood, signals breathing rate when
levels are too high - medulla oblongata
circulatory system consists of what 3 major parts? - - blood
- blood vessels
- heart
,___________, this system cleans up excess fluids and proteins, returning them to circulatory system -
lymph vascular system
name the walls of blood vessels: - tunica intima
tunica media
tunica adventitia
function of blood: - - helps maintain internal environment by carrying raw materials
- removes waste
- helps stabilize pH
- hold 5qts of blood
blood is composed of: - RBC
WBC
platelets
plasma
function of red blood cells: - transports o2 to cells
how long can RBC live up to? - 4 months
where does RBC form? - in bone marrow
function of WBC: - defend against infection
removes wastes
forms platelets for coagulation
name 5 types of WBC - N.E.M.B.L
neutrophils
, eosinophils
monocytes
basophils
lymphocytes
heart is made of what tissue? - cardiac muscle tissue
this tissue is "self-exciting" - cardiac muscle tissue
what separates the atrium from ventricle? - atrioventricular valve
___________________ prevent backflow - valves
the heart has how many chambers? - 4
what is the function of the sinoatrial node "cardiac pacemaker"? - - 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 - coronary
circulation: blood between heart and lungs - pulmonary
