Hitology of The spleen
The splenic parenchyma consists of white and red pulp that is surrounded by capsule and there is trabeculae within the parenchyma.

Fucntion of The spleen
❑Filtration (Macrophages)
❑Immune Function(IgM Antibodies)
❑Storage
❑Hematopoiesis

Blood Supply
Arterial : The spleen is supplied by splenic artery arises from the coeliactrunk .
Venous drainage: The splenic vein runs behind the pancreas.
Nerve supply: Sympathetic nerve fibres.

Splenic Trauma :
• Either Blunt or Penetrating injuries.
• Penetrating Injuries Need urgent surgical Exploration.
• Blunt injuries treated according to The vital status of the injured patient.
• Vitally stable patients with Blunt abdominal injuries Treated conservatively.
• Vitally unstable patient with blunt abdominal injuries need urgent surgical intervention.

Investigations
1.blood test: Hb%, RBS, cross match, prepare blood
