Which of the following sequences shows the pathway of lymph flow through the lymphatic system?*1 pointLymph node – lymphatic vessel – lymphatic capillary – lymphatic ductLymphatic capillary – lymphatic vessel – lymph node – lymphatic ductLymphatic capillary – lymph node – lymphatic vessel – lymphatic ductLymphatic capillary – lymph node –– lymphatic duct– lymphatic vessel
Solution
The correct sequence for the pathway of lymph flow through the lymphatic system is:
Lymphatic capillary – lymphatic vessel – lymph node – lymphatic duct
Here's why:
-
Lymphatic capillaries: These are the smallest, most peripheral parts of the lymphatic system. They are responsible for the initial collection of lymph, which is a fluid that contains white blood cells, proteins, and fats.
-
Lymphatic vessels: Once the lymph is collected, it is transported through progressively larger lymphatic vessels. These vessels have valves that prevent the backflow of lymph.
-
Lymph nodes: As the lymph travels through the lymphatic vessels, it passes through lymph nodes. These nodes contain immune cells that filter the lymph, removing and destroying any harmful substances.
-
Lymphatic ducts: Finally, the filtered lymph is returned to the bloodstream via the lymphatic ducts. There are two main lymphatic ducts in the body: the right lymphatic duct and the thoracic duct.

Following digestion in the small intestine, certain lipids are absorbed by intestinal epithelial cells and packaged into large droplets. These lipid droplets are released from intestinal epithelial cells and transported into the lymphatic system to ultimately drain into a large vein near the heart. Which series shows the order in which these lipid droplets are transported from the intestine to the bloodstream?A.Lymph capillaries → interstitial fluid → lymph vessels → lymph duct → veinB.Interstitial fluid → lymph vessels → lymph duct → lymph capillaries → veinC.Interstitial fluid → lymph capillaries → lymph vessels → lymph duct → veinD.Lymph capillaries → interstitial fluid → lymph duct → lymph vessels → vein
