when a persons body becomes infected by a virus, white blood cells in the blood produce specialized immune cells that help fight the virus and protect the body from infections it can cause. the specialized immune cells, along with other cells, are circulated throughout the body so that the cells can reach the areas of the body that require an immune response.

1. which two body systems interact to protect an individual from a virus

1. blood found in the circulatory system transports many materials, including nutrients, gases, and wastes. which of the following body systems interacts with the circulatory system to get rid of wastes found throughout the body?

a) the digestive system
b) the excretory system
c) the nervous system
d) the muscular system

Explanation:

• For question 8:
• The circulatory system transports the specialized immune cells (as mentioned in the text: "the specialized immune cells... are circulated throughout the body"). So the circulatory system is involved.
• The immune system's role is to fight the virus (as the immune cells help fight the virus). So the immune system is involved.
• For question 9:
• The excretory system's function is to remove waste from the body. Blood (in the circulatory system) transports waste, and the excretory system (e.g., kidneys filtering waste from blood) interacts with the circulatory system to get rid of waste.

Answer:

1. D) Circulatory and Immune
2. B) The excretory system
