Lymphatic System Diagrams Review

Which organ shown in the left upper abdominal quadrant filters blood and helps mount immune responses?

• Cervical lymph nodes

• Appendix lower right abdomen

• Spleen left upper abdomen

• Tonsil in oropharynx

A swollen node behind the knee would most likely belong to which labeled group?

• Cervical lymph nodes in neck

• Inguinal lymph nodes at groin

• Popliteal lymph nodes behind knee

• Axillary lymph nodes in armpit

Which labeled structure forms the outer connective tissue covering of a lymph node as shown in the diagram?

• Sinus within the cortex

• Trabeculae projecting inward

• Germinal center region

• Capsule surrounding the node

Lymph first enters the lymph node through which labeled vessels on the diagram?

• Sinus near the germinal centers

• Trabeculae along the medulla

• Efferent vessels at the hilum

• Afferent vessels at the convex side

A blockage at the hilum would most directly impede which labeled vessels?

• Capsule along outer wall

• Efferent vessels exiting the node

• Afferent vessels entering cortex

• Sinus within the medulla

Lymph collected from most of the body returns to blood by entering which vessel indicated near the shoulder?

• Subclavian vein at venous angle

• Axillary lymph nodes cluster

• Cervical lymph nodes chain

• Popliteal lymph nodes group

Which labeled structure is part of gut-associated lymphoid tissue at the junction of the small and large intestines?

• Tonsil in oral cavity

• Thoracic duct midline

• Appendix near cecum area

• Spleen near left ribs

Which labeled structures extend inward from the capsule to subdivide the lymph node?

• Afferent vessels entering cortex

• Efferent vessels leaving the node

• Trabeculae forming internal partitions

• Germinal centers inside follicles

Which lymph node group is indicated near the groin on both sides of the diagram?

• Cervical lymph nodes in neck

• Inguinal lymph nodes in groin

• Popliteal lymph nodes at knee

• Axillary lymph nodes in axilla

Which structure labeled near the neck region drains lymph into the venous circulation at the shoulder area?

• Axillary lymph nodes in armpit

• Subclavian vein near the clavicle

• Cervical lymph nodes in neck

• Thoracic duct on left side of chest
