Your heart gets a lot of attention from poets, songwriters, and storytellers, but today Hank’s gonna tell you how it really works. The heart’s ventricles, atria, and valves create a pump that maintains both high and low pressure to circulate blood from the heart to the body through your arteries and bring it back to the heart through your veins. You’ll also learn what your blood pressure measurements mean when we talk about systolic and diastolic blood pressure.

So if our heart doesn't have feelings, then y do we feel loved in that particular area.
For example:
You see someone you like (❤️) and then you feel something nice around your heart.
Y does this happen

To all those saying that one more heartbreak can cause their death and it's proven well y'all better study and check the source. Potangina.
