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