arteries can either ________ or _________ - ANSWER-vasodilation or vasoconstriction
Automaticity - ANSWER-heart pumps on its own
baroreceptors regulate what function - ANSWER-blood pressure with positional
changes
Beta 1 activity is where - ANSWER-heart related functions- such as increased heart rate
and strength of contraction
Beta 2 activity is where - ANSWER-pulmonary function of bronchiolar dilation (lungs)
Beta effect is what( two beta categories) - ANSWER-seen in bigger organs, heart and
lungs
blood vessels leading AWAY from the heart are - ANSWER-arteries
blood vessels leading TO the heart are - ANSWER-veins
bradycardia - ANSWER-less than 60
bronchi branch out and become - ANSWER-bronchioles and then alveoli
cardiac cycle - ANSWER-60-100 beats/minute
cardiac output - ANSWER-total amount of blood pumped by the left ventricle in one
minute
closure of the four valves prevents back flow. if valve is damaged then this will be a -
ANSWER-heart murmur or mitral valve prolapse
Dead Space - ANSWER--area where gas will not be exchanged
-extends from the pharynx to the bronchioles
-area is 150 cc of volume space
, diastolic phase is during what part of the blood flow - ANSWER-when the ventricles are
relaxed
diastolic pressure measures what - ANSWER-the pressure in the arteries during the
relaxation of the ventricles
does the AV node speeds up or slows down the impulse - ANSWER-slows down
ectopic pacemakers occur when - ANSWER-when the SA node fails- they will be
produced and take over as the pacemaker

of the tongue
facial artery supplies - ANSWER-the face- located behind mandible
Flow of Blood through the heart - ANSWER-1. right atrium fills with blood
2. contracts- tricuspid valve
3. right ventricle fills with blood
4. contracts- closes tricuspid valve/opens pulmonary valve
5. blood goes through pulmonary artery to the lungs
6. pulmonary veins returns blood to left atrium
7. contracts-mitral valve
8. left ventricle fills with blood
9. Contracts- forces blood through aortic valve into aorta and then the peripheral
circulation.
