Is the heart a muscle?

Question

The heart is made up of cardiac muscle tissue, so would that make the heart a muscle as well? Or is it just an organ, and the muscles inside it are just the muscles.

This is for a biology project, describing about the muscular system. The heart would be the only major structure of the cardiac muscle tissue in the muscular system?

Answer 1

Be careful when classifying parts of the body. The heart is an organ, as is the liver, lungs, etc. An organ is a group of tissues that function together for a main purpose. The heart's purpose is delivering nutrients to the body and returning wastes for removal. Muscle is considered a tissue, which is part of an organ.

Answer 2

The heart is a muscle, I'm pretty sure, because it's an involuntary muscle action, right?

My opinion.

Answer 5

the heart is an organ which consists of muscle tissue, nervous tissue , blood tissue and connective tissue and is surrounded by fat tissue .

Answer 6

yes the heart is a muscle that works like a pump.The heart of a vertebrate is composed of cardiac muscle, an involuntary muscle tissue which is found only within this organ. The average human heart beating at 72 BPM, will beat approximately 2.5 billion times during a lifetime spanning 66 years.

Answer 7

It's an organ, but it's composed of muscular tissue. Cardiac muscle is found only in the heart.
