- Photo title: SA Node and AV Node in the Heart
- Author: 7activestudio
- Cover photo description:
- The SA & x28;sinoatrial& x29; node generates an electrical signal that causes the upper heart chambers & x28;atria& x29; to contract. The signal then passes through the AV & x28;atrioventricular& x29; node to the lower heart chambers & x28;ventricles& x29;, causing them to contract, or pump. The SA node is considered the pacemaker of the heart.
