Verified step by step guidance

Begin by understanding the hierarchy of biological organization in the human body, which progresses from the simplest to the most complex structures.

Recognize that cells are the fundamental building blocks of life, representing the smallest unit capable of performing life functions.

Identify that tissues are composed of groups of similar cells that work together to perform a specific function, such as muscle tissue or nervous tissue.

Understand that organs are structures made up of different types of tissues that work together to perform complex functions, like the heart or liver.

Finally, realize that organ systems consist of multiple organs that collaborate to carry out broader physiological functions, such as the digestive system or respiratory system.
