Question

What are the ten major organ systems in the body?

Answer 1

Circulatory
Respiratory
Excretory
Digestive
Immune
Reproductive
Nervous
Muscular
Skeletal
Hormonal
Integumentary

Explanation:

Some people consider the hormonal and the reproductive to be one system.
Some others do not consider the Integumantary to be a system but rather an organ.
So eleven different ones are written but they can become ten in two different ways.
