**Understanding Heart Sounds: A Quick Guide**

Welcome to our channel! In this video, we’re diving into the fascinating world of **heart sounds**—the essential auditory clues your heart provides during its cycle. These sounds, heard through a stethoscope, give vital insights into heart health and function.

We’ll break down the four primary heart sounds:

- **S1 ("Lub")**: The first sound marks the closure of the mitral and tricuspid valves, signaling the start of ventricular contraction (systole).
- **S2 ("Dub")**: This higher-pitched sound occurs with the closure of the aortic and pulmonary valves, indicating the beginning of ventricular relaxation (diastole).
- **S3**: A softer sound sometimes heard in younger individuals. It results from rapid blood flow into the ventricles but can indicate heart issues in older adults.
- **S4**: Heard just before S1, this sound reflects atrial contraction against a stiff ventricle and may point to underlying heart problems.

We’ll also touch on abnormal heart sounds, like murmurs or clicks, which can signal valve defects or turbulent blood flow.
