Cardiovascular Flashcards
Parts of heart
What are the two circuits?
Pulmonary and Systemic
What does the Pulmonary circuit do?
sends deoxygenated blood to the lungs to get oxygen and release CO2
what does the systemic circuit do?
sends blood and nutrients to all body cells and removes waste
two layers of the pericardium
visceral and parietal
what does the epicardium do and where is it
outer later; reduces friction in heart
what layer is the visceral pericardium
inner most layer
what layer is the parietal pericardium
outer layer
wheres the myocardium and what does it do
middle; pumps blood
what does the endocardium do and where is it
inner; contains elastic fibers
What does the atrium do
receives blood returning to the heart
what does the ventricle do
forces blood out of the heart
what does the septum do
seperates the right and left side
Systole
contract
Diastole
Relax
blood pressure numbers
Systolic and diastolic
Spirometry:
measurement of air volumes in and out of the lungs
Respiratory cycle:
one inspiration plus the following expiration
Tidal Volume:
the volume of air that enters (or leaves) in one respiratory cycle
Residual volume:
remaining air in the lungs after expiration
Vital Capacity:
maximum amount of air a person can exhale after taking the deepest breath possible
Total lung capacity:
vital capacity + residual volume
Inspiration
inhalation
Expiration
exhalation
Erythrocytes
red blood cells
