Question

the human body is made up of many different systems that work together to carry out the functions needed for life. the following systems help the body get oxygen and remove carbon dioxide waste. apply what you learned about the heart to order these systems from the simplest to the most complex. simplest system smooth muscle tissue, which helps the lungs to expand and contract respiratory system, which brings oxygen to and removes carbon dioxide from the blood body, which is made up of multiple interacting organ systems smooth muscle cell, which helps to make up the walls of the lungs lungs, which take in oxygen from the air and release carbon dioxide into the air

Explanation:

Cell is the basic unit of life. Tissue is a group of similar cells working together. Organ is made up of different tissues. Organ - system is a group of organs working together. The body is the most complex as it contains multiple organ - systems. So, we order from the simplest (cell) to the most complex (body).

Answer:

1. smooth muscle cell, which helps to make up the walls of the lungs
2. smooth muscle tissue, which helps the lungs to expand and contract
3. lungs, which take in oxygen from the air and release carbon dioxide into the air
4. respiratory system, which brings oxygen to and removes carbon dioxide from the blood
5. body, which is made up of multiple interacting organ systems
