Heart chambers — roles?
Receive and pump blood through the heart.
Right Atrium — function?
Receives deoxygenated blood from body.
Heart valves — function?
Prevent backflow, ensure unidirectional flow.
Left Ventricle — role?
Pumps oxygen-rich blood into the aorta.
Coronary circulation — purpose?
Supplies oxygen to the heart muscle.
Interventricular Septum — separates?
Right and left ventricles.
Heart valves — purpose?
Prevent backflow, maintain unidirectional flow.
Tricuspid Valve — location?
Between right atrium and ventricle.
Aortic Valve — function?
Allows blood into systemic circulation.
Blood flow pathway — sequence?
Atrium → ventricle → arteries → lungs/body.
