CHAPTER OUTLINE

2. 3.1 The circulatory system transports materials.
The heart, blood vessels, and blood of the circulatory system work together to transport materials from the digestive and respiratory systems to all cells.

heart
blood
red blood cell
blood vessels
The blood exerts pressure on the walls of the blood vessels and keeps the blood moving around the body.

9. The immune system defends the body.
3.2
The immune system defends the body.
The immune system defends the body from pathogens. White blood cells identify and attack pathogens that find their way inside the body.The immune system responds to attack with inflammation, fever, and development of immunity.

17. The integumentary system shields the body.
3.3
The integumentary system shields the body.
The skin protects the body from harmful materials in the environment, and allows you to sense temperature, pain, touch, and vibration.
integumentary system
In most cases the skin is able to heal itself after injury.
