right and left VENTRICLES
|
|
|
what do the ventricles do?
|
they form the bulk of the heart and are the discharging chambers that push blood to various places in the body.
|
|
|
Interatrial or Interventricular septum

|
Deoxygenated blood comes TO the heart and is drained into the right atrium though one of two major vessels... what are they?
|
the superior vena cava and the inferior vena cava
|
|
|
superior vena cava
|
drains blood from the upper body (head, neck, and forelimbs)
|
|
|
inferior vena cava
|
drains blood from the trunk and lower body
|
|
|
Tricuspid Valve
|
a valve with three flaps found between the right and left atrium and ventricle.
|
|
|
Chordae Tendinae
|
fibrous strands that attach the tricuspid valves to the muscular wall of the right ventricle
|
|
|
Pulmonary Trunk
|
this divides into two pulmonary artieries that convey the blood to the lungs for gas exchange
|
|
|
semi-lunar valve
|
a valve between the right ventricle and the pulmonary trunk that prevents the backflow of blood.
|
|
|
how does oxygenated blood return to the heart?
|
through two pulmonary veins
|
|
|
Bicuspid valve, or the mitral valve
|
a valve with two flaps; between the left atrium and left ventricle, its a chamber to prevent the backflow of blood.
