Thank you for including the answers! 🤗

11/11, thanks to college anatomy. Good quiz!

R Yancey, The diaphragm is indeed an organ. Organs are defined as a collection of tissues that structurally form a functional unit specialized to perform a particular function. Without your diaphragm, you could not breath. The diaphragm is a muscle that helps you inhale and exhale. That means the diaphragm qualifies as an organ. It is as important as your heart and lungs are. You would die without it. The diaphragm is an organ.

Yes, diaphragm is NOT an organ, not even a piano!
