LR267.3.3: Formative Levels of Organization

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.

Draggable item		Corresponding Item
muscle		covers the surfaces of the body
nervous		messages between the brain and the other parts of the body
connective		makes the body move
epithelial		provides the support for all the body's parts

Check for Understanding:

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:

Digestive System:  Breaks down food small enough to give to the cells and provides energy.

Circulatory System: Carries the food, water, and oxygen to the cells throughout the body and removes waste.

Respiratory System: Transports oxygen into and carbon dioxide out of the blood.

Nervous System: Sends messages throughout your body.

Excretory System: Removes waste from your body.

Muscular System: Helps your body move.

Skeletal System: Protects the soft tissue and organs in your body.

Endocrine System: Uses hormones to regulate growth and development.
