Flashcards in other Deck (13):
1

circulation pattern (starting with pulmonary)

right side of heart > pulmonary arteries > lungs > pulmonary veins > left side of heart > systemic arteries > blood delivers oxygen to tissue then enters systemic veins

2

pulmonary arteries

travel to the lung to take up oxygen so pulmonary veins carry oxygen rich blood

3

pericardium function

prevent heart from bouncing in thoracic cavity, creates frictionless environment through production of serous fluid, prevents heart from overfilling with blood

4

pulmonary semilunar valve

between right ventricle and pulmonary trunk

5

aortic semilunar valve

between left ventricle and assending aorta

6

intercalated discs

cell-cell contacts that electrically and mechanically link cells together, permitting immediate passage of muscle impulse

7

purkinje fibres

fibres that extend through ventricle walls and allow rapid, immediate spread of impulse through ventricular myocardium.

8

cappilaries

have only tunic intima

9

blood pressure

highest in arteries close to heart and lowest in veins

10

sequence of systemic blood flow

left ventricle > aorta> elastic arteries > muscular arteries > arterioles > systemic capillaries >venules > veins > SVC or IVC

11

pumping of deoxygenated blood

right ventricle and atrium

12

ventricle contraction

AV valce closure

13

pulmonary veins

carry oxygenated blood from lungs to heart
