One of the two lower chambers of the heart; receives blood from the atria and pumps it into the systemic or pulmonary circulation.
|
Right and Left Ventricles
|
|
|
The muscular wall that separates the two ventricles and the two atria.

|
|
Collects oxygen-poor blood coming from the tissues in the head, chest, and arms.
|
Superior Vena Cava
|
|
|
Collects oxygen-poor blood coming from the tissues elsewhere in the body.
|
Inferior Vena Cava
