Lymphatics Quiz - OpenStax A&P Ch 21

How does the lymphatic system contribute to maintaining fluid balance in the body on a daily basis?

• Returns 3 liters of excess interstitial fluid to the circulatory system.

• Generates 3 liters of lymph fluid daily.

• Absorbs 3 liters of nutrients from the digestive tract.

• Transports 3 liters of oxygen to tissues.

What role do lymph nodes play in the immune response?

• They produce red blood cells.

• They serve as staging areas for critical immune responses against pathogens.

• They transport dietary lipids.

• They block fluid accumulation.

How does the lymphatic system assist in lipid transport?

• It breaks down lipids in the liver.

• It carries dietary lipids and fat-soluble vitamins absorbed in the gut to the bloodstream.

• It stores lipids in lymph nodes.

• It converts lipids into proteins.

What is the function of immune cell transport in the lymphatic system?

• It provides pathways for immune cells to travel throughout the body to fight infection.

• It stores immune cells in the liver.

• It produces immune cells in the bone marrow.

• It converts immune cells into red blood cells.

What is the function of lymphatic capillaries in the lymphatic system?

• They transport oxygen to tissues.

• They are vessels where interstitial fluid enters the system.

• They produce red blood cells.

• They store nutrients for the body.

What gives lymphatic vessels their beaded appearance?

• The presence of lymph nodes.

• The three-tunic structure and one-way valves.

• The accumulation of lymphocytes.

• The presence of red blood cells.

How are lymphatic trunks formed?

• By the fusion of lymphatic capillaries.

• By the merging of superficial and deep lymphatics.

• By the division of lymphatic vessels.

• By the accumulation of lymph fluid.

Where do the right lymphatic duct and thoracic duct empty lymph?

• Into the heart.

• Into the liver.

• Into the bloodstream at the subclavian veins.

• Into the kidneys.

What is the structure of lymphatic capillaries?

• Two cell-thick layer of endothelial cells

• One cell-thick layer of endothelial cells with overlapping cells

• Three cell-thick layer of endothelial cells

• One cell-thick layer of smooth muscle cells

What is the function of collagen filaments in lymphatic capillaries?

• To prevent fluid entry

• To anchor capillaries to surrounding structures

• To transport dietary lipids

• To increase blood pressure
