Septa
Walls that divide the four chambers of the heart
All veins ____ blood toward the heart
Carry
All arteries carry blood ____ from the heart
Away
How does blood circulation go through the heart?
Right Atrium → Right Ventricle → Pulmonary Artery → Lungs → Left Atrium → Left Ventricle → Aorta → Rest of the body
Bicuspid Valve (or Mitral Valve)
The atrioventricular valve that connects the left atrium to the left ventricule
Tricuspid Valve
The atroventricular valve that connects the right atrium to the right ventricule
The atrium and ventricle of each side are connected by an ____
Atrioventricular valve (AV)
The Tricuspid Valve is named for it’s ____
Three cusps
What do the cusps in the Tricuspid Valve do?
