Directions: ANSWER USING COMPLETE SENTENCES! Use the information you have been given to answer questions about: How the Body Fights Disease.

Level#1: Your body has many different ways too fight diseases. It tries to keep the pathogens from getting too far into your body. Different body parts have features that block or kill pathogens. One of the body's defenses is the skin. Layers of dead skin cells stop pathogens form entering the the body. Oil contained in the skin also helps to kill pathogens. The mouth has enzymes that kill pathogens. The stomach has acids that kill pathogens. The nose has mucus and hairs that help to trap pathogens so they cannot get further into the body.

1. What does the body do to fight diseases?





2. How do our different body parts keep us from getting diseases?






3. how does the skin help to protect the body against diseases?

The mouth has enzymes that kill pathogens. The stomach has acids that kill pathogens. The nose has mucus and hairs that help to trap pathogens so they cannot get further into the body. The respiratory system's airways and lungs are lined with cilia. Cilia are hair-like structures that are covered with mucus. They move back and forth in a sweeping motion. The mucus on the cilia catches dirt, dust, and germs. The cilia then pushes mucus up toward your throat. Then, you swallow the mucus or you spit it out. In this way the cilia and mucus work together to help keep dirt, dust, and germs out of your lungs. Sneezing is also a way of getting rid of dirt, dust, and pathogens.

White blood cells attack disease pathogens when they enter the body. When your skin is broken, such as when you get a cut, pathogens can enter the body through the cut. White blood cells travel through the blood vessels to the area of the cut. Then, they destroy harmful pathogens. Sometimes, a cut will ooze white or yellow liquid. This is pus. Pus is actually a pool of dead white blood cells and other tissues. If pus is present, it means the cut is infected.

1. Explain how the body tries to fight diseases and what different body parts do to assist in this process.







2. Explain how the skin protects the body against diseases.






3. Explain how the mouth, stomach, and nose protect the body against diseases.
