It is lunchtime at school. Juliana walks to the cafeteria, buys her lunch, sits down with her friends, and eats her lunch. These tasks may seem simple, but in fact, Juliana's body is working very hard. Each part of the human body performs a specific job, and the parts all work together to allow the body to function.
The smooth functioning of the human body is due in part to how it is organized. Below are the levels of organization in the human body.
Rearrange the words below to show the level of organization in the human body from least complex (on the top) to most complex (on the bottom)
organism
cell
organ
organ system
tissue
Drag the images to match the levels of organization.
Compare the levels of organization in a human body to those in a country. Match the terms to show which levels of organization in the human body represent the different parts of a country.

1. Each part of the human body performs a specific job. The smooth functioning of the body is due partially to how it is organized.
The cells, tissues, and organs in the human body each have a structure that is created for a specific function. The pictures below show how their structures relate to their functions.
Match each type of cell with its function.
Tissue is made up of a group of similar cells that have the same function. The body contains several types of tissue. The images below teach us about four of the main types of tissues and their functions.
The job of blood is to carry food and oxygen to, and waste from, all of the body's parts. Which type of tissue is blood tissue?
The stomach is made up of all four types of tissue: connective, nervous, epithelial, and muscle. How might the stomach be affected if the muscle tissue no longer worked correctly?

1. The cells, tissues, and organs in the human body each have structures that are created for a specific function.
2. The four main types of tissue in the human body are epithelial, connective, muscle, and nervous.
Organ Systems:
1. Digestive System: Breaks down food small enough to give to the cells and provides energy.
2. Circulatory System: Carries the food, water, and oxygen to the cells throughout the body and removes waste.
3. Respiratory System: Transports oxygen into and carbon dioxide out of the blood.
4. Nervous System: Sends messages throughout your body.
5. Excretory System: Removes waste from your body.
6. Muscular System: Helps your body move.
7. Skeletal System: Protects the soft tissue and organs in your body.
8. Endocrine System: Uses hormones to regulate growth and development.
Drag the names of the organ systems to the correct locations below.
