Where is the spleen located in the human body?

• Lower left quadrant of the abdomen

• Lower right quadrant of the abdomen

• Upper left quadrant of the abdomen

• Upper right quadrant of the abdomen

What is the function of the fibrous capsule surrounding the spleen?

• To form short extensions called trabeculi

• To produce lymphocytes

• To store red blood cells

• To connect the spleen to the stomach

Which surface of the spleen fits into the concavity of the left hemidiaphragm?

• Inferior border

• Lateral or diaphragmatic surface

• Visceral surface

• Medial surface

What is the primary blood supply to the spleen?

• Celiac trunk

• Splenic artery

• Renal artery

• Hepatic artery

Which ligament connects the spleen to the stomach's greater curvature?

• Lesser sac

• Frenococolic ligament

• Gastrosplenic ligament

• Spleno renal ligament

What are the two main tissue types found in the spleen?

• Trabeculi and hilum

• Cortex and medulla

• White pulp and red pulp

• Lymph nodes and follicles

What is the primary function of T lymphocytes in the spleen?

• To recognize specific antigens and coordinate immune responses

• To capture and present antigens

• To produce antibodies

• To store iron

What role does the spleen play in blood filtration?

• It filters lymphatic fluid

• It removes damaged or abnormal red blood cells

• It stores iron

• It produces white blood cells

How does the spleen respond to severe tissue injury?

• By increasing iron metabolism

• By storing more red blood cells

• By producing more lymphocytes

• By releasing monocytes to regulate inflammation

In what circumstance can the spleen resume its hematopoietic role?

• When bone marrow function is compromised

• In response to infection
