Circulation - the movement of blood through the body
Respiration - organs and tissues that help you breathe
Digestion - breaks down food into simple nutrients (carbohydrates, fats and proteins)
Organ System
A structure made of two or more tissue types that work together to carry out a particular function.
- Have anatomical boundaries and are visibly able to differentiate from close structures.
Organ
T or F. The large organs visible to the naked eye, often has smaller organs that you can only see with a microscope.
True
