Construct a scientific explanation (make a claim and use evidence to support your claim) to answer the questions, “What are the components and functions of the lymphoid system?” and “What defenses have evolved against foreign invaders?”

The key functions of the lymphatic system:

Drains excess fluids and profteins from tissues all around the body and returns them back into the bloodstream.

Removes waste products produced by cells.

Fights infections.

Absorbs fats and fat-soluble vitamins from the digestive system and transports these into the bloodstream.

Not only can certain viruses outwit your immune system's defenses, but genetic malfunctions can result in an ineffective immune system.

The Human Immunodeficiency Virus (HIV), infects the CD4+ T-cells, a type of lymphocyte, causing the cells to die. If enough cells are killed, the immune system no longer functions and the person becomes susceptible to many different diseases.

An example of a genetic disease of the immune system is lupus which causes your immune system to mistakenly attack your body’s healthy cells.
