Where is the pulmonary trunk?
|
the pulmonary trunk branches from the right ventricle
|
|
What is the function of the pulmonary trunk?
|
branches out into pulmonary arteries which take blood to the lungs
|
|
Where are atrioventricular valves?
|
between the atria and the ventricles
|
|
What do atrioventicular valves do when open?
|
blood flows to the ventricles from the atria b/c of greater blood pressure in the atria
|
|
What do atrioventicular valves do when closed?
|
the valves prevent blood from flowing from the ventricles to the atria
|
|
Where are the chordae tendineae found?
|
by the atrioventricular valves
|
|
What is the function of the chordae tendineae?
|
to insure atrioventricular valves don't invert during ventricle contractions
|
|
What are chordae tendineaes made of?
|
tendon like structures of protien
|
|
What are semi-lunar valves?
|
valves whose flaps resemble half moons
|
|
Where are semi-lunar valves?
|
between the r. ventricle and the pulmonary trunk
between the l. ventricle and the atora |
|
The pulmonary semilunar valve
Where it is: What it does: |
-lies between the r. ventricle and the pulmonary trunk
-blood flows out of the r. ventricle but not back into it |
|
The atoric semilunar valve
Where it is: What it does: |
-lies between the l. ventricle and the atora
-blood flow from the l. xentricle to the atora |
|
Where is the septum found?
|
