LYMPHATIC SYSTEM PRACTICE QUESTIONS
WITH DETAILED EXPLANATIONS 2026
◉ Components of the Lymphatic System.
Answer: Includes lymph, lymphatic vessels, lymph nodes, spleen,
thymus, tonsils, and lymphoid tissues.
◉ Roles of Lymphatic Components.
Answer: Vessels transport lymph, nodes filter pathogens, spleen
filters blood, thymus matures T cells, and tonsils trap pathogens.
◉ Lymphatic vs Blood Vascular System.
Answer: The lymphatic system returns excess fluid and supports
immunity, while the blood vascular system circulates oxygen,
nutrients, and wastes.
◉ Formation of Lymph.
Answer: Lymph forms when interstitial fluid (leaked plasma) enters
lymphatic capillaries.
◉ Composition of Lymph.
Answer: Contains water, proteins, lipids, and immune cells such as
lymphocytes.
, ◉ Transport of Lymph.
Answer: Lymph moves through vessels via skeletal muscle
contraction, pressure changes, and one-way valves.
◉ Lymphatic Drainage Pathway.
Answer: Lymph flows from capillaries → vessels → lymph nodes →
trunks → ducts → subclavian veins.
◉ Right Lymphatic Duct Drainage.
Answer: Drains lymph from right upper body into right subclavian
vein.
◉ Thoracic Duct Drainage.
Answer: Drains lymph from the rest of the body into left subclavian
vein.
◉ Immunological Memory.
Answer: Allows faster and stronger immune responses upon
repeated exposure to a pathogen.
◉ Specificity in Immunity.
Answer: Immune cells recognize and respond to specific antigens.
