Lymphatic System DOL LESSON 1

What are the three main functions of the lymphatic system?

• Maintaining fluid balance, defending against disease, and transporting dietary fats.

• Filtering impurities from the lymph, providing a home for lymphocytes, and regulating healthy bacteria in the large intestine.

• Removing old and damaged red blood cells, developing T cells, and protecting the body from pathogens.

• Recognizing and destroying harmful pathogens, collecting and returning escaped fluid into the bloodstream, and filtering impurities from the lymph.

Which structures make up the lymphatic system?

• Lymphatic capillaries, vessels, trunks, nodes, and ducts.

• Spleen, thymus, MALT, tonsils, and Peyer's patches.

• Right lymphatic duct and thoracic duct.

• Collarbone, skeletal muscles, and lymphocytes.

How does the lymphatic system maintain fluid balance?

• By recognizing and destroying harmful pathogens.

• By collecting, filtering, and returning escaped fluid into the bloodstream.

• By removing old and damaged red blood cells.

• By transporting dietary fats from the digestive system to the rest of the body.

How does the lymphatic system contribute to the body's immune response?

• By filtering impurities from the lymph and providing a home for lymphocytes.

• By transporting dietary fats from the digestive system to the rest of the body.

• By collecting, filtering, and returning escaped fluid into the bloodstream.

• By removing old and damaged red blood cells and platelets.

What is the role of Mucosa-associated lymphoid tissue (MALT) in the lymphatic system?

• To filter the blood by removing old and damaged red blood cells and platelets.

• To develop and mature T cells responsible for destroying pathogens and cancer cells.

• To protect the body from pathogens that enter through areas like the nasal cavity, mouth, and lungs.

• To trap pathogens that enter through the mouth and nose.
