cardiovasuclar system Flashcards
what are the 3 functions of the cardiovascular system
transporting
controlling blood temp
protecting
what are the 4 valves called and what side are they on
tricuspid left
bicuspid right
pulmonary valve
aortic valve
what is the function of the valves
prevent backflow of blood
where does the blood start and end 🚂🚂
right atrium
tricuspid valve
right ventricle
pulmonary valve
pulmonary artery
pulmanary vein left atrium bicuspid valve
left ventrical
aortic valve
aorta
vena cave
heart during excersie
what is stroke volume
and the average
amount of blood pumped out the left ventricle per beat
average 70ml
what is the cardiac output
amount of blood pumped out the left ventricle per minute
what happens during excersie to the heart
heart contracts powerfully
what happens to the heart if you do regular exercise
becomes bigger, stronger , stroke volume increases, lower resting heart rate
long term effects cardiovascular system
bigger stronger heart
lower resting heart rate
increased blood supply
short term effects cardiovascular system
increased heart rate
increased stroke volume
increased cardiac output
what are the 4 blood vessels
veins
arteries
capillaries
valves
what do veins do structure and function
carry blood back to the heart
thin layer of muscle
thin outer wall
wide lumen
what is the structure function of arteries?
carries blood away from the heart
thick outer wall
thin layer of muscle
narrow lumen
what is the function and structure of capillaries
one cell thick
transport blood
what is the function of blood
transports oxygen and nutrients
