volumes
The amount of air inhaled and exhaled with each breath
Tidal volume (VT)
(IC)
Inspiratory capacity the volume of air remaining in the lungs after normal exhaustion
blood regulates what
pH and osmosis
-major substance of RBCs
- accounts for the red color -primary function of O2 and CO2 transport
-has 4 heme groups - 4 amino acid groups
cough reflex?
-foreign matter in the trachea or large bronchi activates cough reflex
(IRV)
Inspiratory reserve volume: the amount of air that can be forcibly inhaled beyond the VT
Functional residual capacity (FRC)
the volume of air remaining in the lungs after a normal exhalation
blood maintains what
Body temp
WBC protects what
-Protects the body against invading microorganisms and remove dead cells and debris from the body
what effects does aging have on Elastic recoil and compliance of the lungs
Elastic recoil of the lungs decreases lung compliance increases
Expiratory reserve volume (ERV)
The amount of air that is forcibly exhaled after a normal VT
(TLC)
Total lung capacity: the maximum amount of air that the lungs can accommodate
blood protects against?
Foreign substances
Ventral respiratory groups (VRGs)
neurons are responsible for triggering what? and what happens when they are suppressed and by?
Inspiration
-Rate -depth - breathing rhythm
breathing stops when neurons are suppressed
- overdose of morphine , alcohol
what is a normal PH
7.35. 7.45
(RV)
Residual volume (RV) the amount of air still in the lungs after a forced ERV
arteries do what
carry blood away from the heart
blood forms?
CLOTS
Dorsal Respiratory groups (DRGs)
located and does what
-posterior region of the medulla oblongata near the root of cranial nerve IX
-Assimilate (take in) the various factors that influence breathing or a responsible for coordinating the rhythmicity of respiration
nose does what
-filters - humidifies - warms
Vital capacity
(VC) the maximum volume of air that can be exhaled after a maximal inspiration
carry blood back to the heart
blood transports?
Oxygen to tissue cells and carbon dioxide to the lungs for gas exchange
nutrients and waste products , processed molecules from one part of the body to another
Irritant Reflex is? and causes?
Anything that can cause coughing - airway trying to protect itself)
-increase ventilation -cough - sneeze - bronchoconstriction
Blood flow through the heart?
-superior and inferior vena cava - right atrium - tricuspid valve - right ventricle - pulmonary semilunar valve - pulmonary trunk through pulmonary arteries - lungs - left atrium - mitral valve/ Bicuspid - left ventricle - aortic valve - aorta out to the body
