Question

The human body is composed of organ systems. which list represents a system organized from least to most complex?

Answer 1

The human body is organized at different levels, starting with the cell. Cells are organized into tissues, and tissues form organs. Organs are organized into organ systems such as the skeletal and muscular systems

Answer 2

Answer:

The human body, from least to most complex, is composed by Hydrogen and Oxygen atoms in a Chemical Level, here all atoms bond to form molecules, which forms water molecules.

Then, we have the Cellular Level, here a group of molecules bond to from fluid and organelles of a cell.

The next level is the Tissue Level, a group of similar cells join to form tissue, which forms the smooth muscle tissue.

Then, two or more tissued group to form organs, this is the Organ Level. So, a group of organs form the Organ System Level, here two or more organs has specific function to maintain the body.

And the last stage is the Organismal Level which is formed by a group of systems that perform specific functions to maintain the whole body alive.

In resume, the levels are: chemical, cellular, tissue, organ and organismal. From least to most complex.
