Question

Are breathing & heartbeat visible movement?

Answer 1

Breathing is the spontaneous taking in and giving out of the air from the lungs. It takes place due to movements of the ribcage and abdomen, which are visible.

While beating of the heart isn't always visible normally. It can be seen through ultrasound in the fetus when it's faint. For adults, what we feel as a heartbeat is a pressure created on blood vessels because of pumping of the heart.
