Directions: ANSWER USING COMPLETE SENTENCES! Use the information you have been given to answer questions about: The Lymphatic System

Level#1: As blood moves through the body, some fluid leaks into body tissues. As much as three quarts of fluid can leak into body tissue per day. The lymphatic system collects this fluid and returns it to the circulatory system. This clear fluid, called lymph, contains special white blood cells. These white blood cells, called lymphocytes, fight disease.

1. What is the clear fluid called?






2. What does the clear fluid contain?






3. What are the white blood cells called and what do they do?








Level#2: As blood moves through the body, some fluid leaks into body tissues. As much as three quarts of fluid can leak into body tissue per day. The lymphatic system collects this fluid and returns it to the circulatory system. This clear fluid, called lymph, contains special white blood cells. These white blood cells, called lymphocytes, fight disease. Lymph moves through vessels and special organs, including the tonsils, thymus, spleen, and lymph nodes. Lymph is filtered by the lymph nodes and tonsils. When you have an infection, your lymph nodes or tonsils can become larger.

1. Where does lymph move through?






2. What is lymph filtered by?





3. What happens when you have an infection?










 Level#3: As blood moves through the body, some fluid leaks into body tissues. As much as three quarts of fluid can leak into body tissue per day. The lymphatic system collects this fluid and returns it to the circulatory system. This clear fluid, called lymph, contains special white blood cells. These white blood cells, called lymphocytes, fight disease. Lymph moves through vessels and special organs, including the tonsils, thymus, spleen, and lymph nodes. Lymph is filtered by the lymph nodes and tonsils. When you have an infection, your lymph nodes or tonsils can become larger. They become filled with a large number of white blood cells that are fighting bacteria or virus causing your infection. The thymus gland helps certain white blood cells to grow. The spleen destroys damaged red blood cells.

1. Explain what happens to your lymph nodes and tonsils when you have an infection.







2. Explain what the thymus gland does.






3. Explain what the spleen does.
