LYMPHATIC SYSTEM HIGH-YIELD TOPICS
SUMMARY 2026
◉ 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.
◉ Self vs Non-Self Recognition.
Answer: Immune system distinguishes body cells from foreign
invaders to avoid attacking itself.
◉ Autoimmunity Definition.
Answer: Condition where the immune system attacks the body's
own tissues.
◉ Examples of Autoimmune Diseases.
Answer: Includes lupus, rheumatoid arthritis, and type 1 diabetes.
◉ B Cells Role.
Answer: B cells produce antibodies and carry out humoral immunity.
