Answer 2

• A one-way valve separates each atrium from each ventricle.
• The tricuspid valve is located on the right side of the heart, whereas the mitral valve is located on the left.

• The regular closure of the heart valves as blood is pushed in and out of the chambers produces the distinctive 'lub-dub' sound of a heartbeat.

• The sinus node, a group of cells in the right atrium that regulates heart rate, is responsible for this.
• The atria contract initially, followed by an electrical impulse to the atrioventricular node, which is located between the atria and the ventricles.
• The ventricles constrict after a brief pause.
• heart beats 60 to 100 times per minute while you are at rest.
