Use models to recognize the organizational structure of humans as a multicellular organism (cell, tissue, organ, system, organism). The heart pumps blood throughout the body, while the lungs bring in oxygen. Together, these organs are part of the circulatory system. At which level of organization do the heart and lungs belong?

• The heart and lungs are at the tissue level because they are made of groups of similar cells.

• They are at the organ level because each has a specific job within a larger system.

• They belong to the cellular level because they are made of individual cells.

• They function at the system level because they work independently from other organs.

Which level of organization is made up of groups of tissues working together to perform a specific function?

• Cell

• Organ

• System

• Organism

Each body system has a specific job that helps keep you alive and healthy. Which of the following correctly matches a body system with its main function?

• The circulatory system carries oxygen and nutrients throughout the body.

• The digestive system controls how fast your heart beats.

• The skeletal system pumps blood to all parts of the body.

• The nervous system breaks down food into nutrients.

The nervous system is like the body’s command center. It sends messages to different parts of the body to make sure everything is working properly. Which of the following is an example of the nervous system in action?

• Your stomach breaks down food into nutrients after a meal.

• Your heart pumps blood to your lungs to get oxygen.

• You quickly pull your hand away after touching something hot.

• Your bones provide support to help you stand upright.

The digestive system and circulatory system work together to keep your body healthy. What is the main role of the digestive system in this teamwork?

• To deliver oxygen to the body’s cells

• To break down food into nutrients the body can use

• To send messages to the brain about hunger

• To help the body move and stay balanced
