Study Notes
Human Heart
- Four-chambered
- Two atria (relatively small, upper chambers)
- Two ventricles (larger, lower chambers)
- Septum: solid wall of tissue separating chambers
Inter-atrial Septum
- Thin, muscular wall
- Separates right and left atria
Inter-ventricular Septum
- Thick-walled
- Separates right and left ventricles
Atrio-ventricular Septum
- Thick fibrous tissue
- Separates atria and ventricles of the same side
