Heart Sounds Explained 🫀

Описание: The “lub dub” sound of your heartbeat is the CLOSING of the valves, not the opening! 🫀✨

🔊 S1 = “Lub”
Happens when the atrioventricular (AV) valves close — that’s the tricuspid and mitral valves shutting after blood flows from the atria to the ventricles.

🔊 S2 = “Dub”
Occurs when the semilunar valves (aortic and pulmonic) close, right after the ventricles have pumped blood out to the body and lungs.

💡Lub = start of systole
💡Dub = start of diastole

A message from Kristine, founder of NurseInTheMaking📣
My name is Kristine and I survived nursing school…and you can too!
Nurse In The Making was inspired during my time in nursing school. I immediately struggled and decided to create my own study guides. These guides have helped me personally as well as many others make nursing school just a little more manageable.I hope you find comfort knowing that everyone struggles at times. Nursing school is emotionally and physically draining. I hope these informative, clean, and simple guides help you navigate through all the information because there is A LOT of it in nursing school.

Happy Studying Future Nurses. Don't forget to enjoy the journey!
